#JanBeta #Commodore #C16 - วิทยาศาสตร์และเทคโนโลยี
... do we want to watch something on Netflix? .... NO, let's watch Jan Beta! :-) Greetings, Doktor64!
Yes Jan Beta, look better than boring movie,
i don't get Commodore, and i never use it, but i like it when i read that book:
archive.org/details/How_to_Program_Commodore_64_BASIC_for_Beginners
Lovely to see some sad old machines get brought back to life!
Thanks! Doing my best to preserve the machines of the past. :)
The C16, first computer I ever had which my dad got from the tip and he soon realised was a power supply issue which from memory he ended up swapping out for an Amstrad 30yrs ago. Nostalgic watching you take these apart.
You are a perfect example of "knowledge is power". I could spend the rest of my life trying to guess what's wrong. Congratulations!
I love my Commodore 16. Recently I upgraded it to 64k memory, so now it can run all the Plus/4 games and demos.
I have two, both 64er now!
Nice! I much prefer the keyboard of the C16 over the Plus/4. Probably because I've been a C64 user since 1983 and like that keyboard a lot :-)
Totally agree, upgraded to 64k in one of my C16 machines so I could run the Plus/4 stuff but get the benefit of the superior keyboard of the C16
@@StuartCowan I want to do mine. Yes much better than the Plus/4, keyboard, easier to find a replacement PSU etc... and besides if you have a Plus/4 it's a good idea to pull the built in useless software chips (runs cooler I think) so might as well have an upgraded C16 😀
Friend, how could you upgrade and where did you get the necessary parts?
Any link where to buy the pieces and how to do that?
Thank you
It's great to see another video from you, Jan!
As for the key "stem" you may use a Lego axle, It's a perfect fit (some glue might be needed) Credits to Perifractic
Yes, saw that. :D
Thank You for continue making those videos Jan! I realy love them. :)
Thank you! More to come. :)
Cheers Jan, always enjoy watching your vids!
Thanks Rob! :)
Crazy Commodore! I just figured out that the PSU of the 16 is center neg, and the one of the 116 is center pos!
Große Klasse Jan! Dankeschön!
Nostalgia Mode ON. I have years ago C-116 and C-16. I wish I could get one once again.
Definitely get one if you get the chance! :)
Thank you so much Jan! I received the package today :D
Will give it a restore to its former glory together with the kids.
That’s great news! May it continue to live for a long time and bring you joy. (Don’t forget to put heatsinks in!) ;)
@@JanBeta I wonder what kills the processors in theese machines? Think its heat or bad power?
I will try to cool down CPU and TED. Would you do any other chips?
DomedagsPoeten I did CPU, TED and PLA in mine. The rest doesn’t get as warm. I think they got the manufacturing process wrong for the main ICs so they degrade more than necessary especially with heat cycling.
well done Jan
A C16 or Plus/4 is on my wanted list of old Commodore computers as well as a VIC-20. I do have a 64 and I love it so much! I was born just a little too late so I missed these machines' glory days, but thankfully it is not that hard to get software from the internet to work on the original hardware so even I who got very late into the C64 can enjoy it. Since I sometimes stream from my C64 I gotta check out that website you mentioned. Sounds cool to hang out with other Commodore streamers :) Nice video once again Jan!
Oh, you can also become a part of commodore streamers.net if you like. Always open for new people. Do you have a Twitch channel?
@@JanBeta Yes I have. It's under the same name as my TH-cam name :) But soon I'm going to try to beat all the games in the Sega Mega Drive Mini on stream so that's going to take alot of my time for a few months. That's why I'm hesitating a bit to join the site right now as I will not have so much time to stream C64 when the Mega Drive Mini gets released this september.
Check for oxidation in the chip sockets and also the pins.Try to polish them using fiber glass brush.Check electrolytic capacitors,despite the fact that are small values may cause serious malfunctions,or first try to heat motherboard with a heat gun to see if something start to work after the applied temperature.Some zeners,pcb track oxidation,some voltage regulators of transistors,but to have problem in the chipset ic's it is a bit difficult.These machines never stretched or work on continous basis,so the failures are more corrosion than destructive.

That's what I always think to myself while enjoying a pint of IPA
India Pale Ale? :-D
Great stuff Jan!!! So many bad CPUs =/ VSS = ground btw (Voltage Source Source)!
Ah, VSS is source source. Makes sense, thanks! :D
Well done Jan! I've recently gone through the same thing with a few 16's and Plus4's, geat machines! I'm back onto Vic20's here at the moment after picking a couple up at a bargain price, even one with a PET keyboard :-) Keep up the awesome work buddy!
This was so cool to watch. It really makes me remember my very first computer, a commodore VIC-20. Damn thing cost me nearly half a months salary at the time...
Thank you! I have a Vic 20 to fix, too. There's eventually going to be another video about that, too. :)
@Jan Beta That will be so great, can’t wait! Just recently came across your channel and I’m really enjoying it! I’m actually going back and watching your older posts, thank you for your time! Buddy
To reverse polarity, you can get small adaptors to go on the end of the plug. Only a couple of quid, and saves re-soldering wires, etc. Quite useful for using modern PSUs on retro equipment.
It would be safer in the long run to modify the unit to add polarity protection. Just put a small bridge rectifier between the DC in jack and the motherboard. It could be accomplished in a couple of ways, either cutting traces on the motherboard or removing the DC in jack and making a small PCB with the bridge rectifier on it.
This would allow you to use a power supply of either polarity, and even AC power supplies. It'd basically make the unit idiot proof.
You could go further and implement a crowbar circuit for over voltage protection, which would protect it from faulty power supplies. Old unregulated linear wall warts have a tenancy to drift upwards in voltage over time from the windings shorting together due to the insulating varnish deteriorating or migrating from heat and vibration.
Nice! Another great video, keep up the good work!
Thank you! :)
Sweet repairs Jan. Never knew you had a website, cool. Will check it out.
Thanks! Not much on the website yet but I have plans. ;)
My Dear and First Computer :) :) :)
What a wonderful video. Really clear and explanatory. Exactly what i wanted. Website is a pure dream as well. Off to the bench I go with my black screen C16 under my arm.
Hope you manage to fix it! Statistically, it’s got to be the CPU. ;)
Great video. Learned so much!
Glad you liked it. Thank you! :)
@@JanBeta Of course i like it. I really like your channel. The plus/4 was my first computer and recently i did a software project for this machine. Watch my humble videos.:)
A tip is to power the machine from a lab power supply when testing. Makes it a lot easier to see if it draws too much current and also to set safe current limits to prevent any further damage in case of a short.
Yes, good idea. Didn't think of that in this case.
I have not looked at the bread-bin type C16 case to see of the repair kits will work. I do have one though so I will have a look. I recently found out that the early VIC20 cases have different bottom PCB standoffs, they are lower and have a smaller hole than the later cases.
I'll have a look, too. The hinges look similar to the C64 cases I think.
My first computer :)
I highly recommend using a hot air gun after desoldering and before pulling out the ICs. Since I do this, no problems at all any more when desoldering any ICs.
Yes, I do that in case the ICs don't come out easily. Desoldering went pretty well with these C16 chips though. No need for hot air.
The terrilbe 8501... I have four Commodore 16s in the attic with a broken CPU. Two of them were broken when I bought them, from the other two I removed the CPU in order to repair Plus/4s with broken CPUs. As the Plus/4 is the much nicer machine, it makes sense to have the Plus/4s in working condition over the C16. FPGA replacements for the 8501 exist, but the high investment for what are not the best retro computers makes me reluctant to do it.
Yes, I love the Plus/4, too. I luckily have a working one (it still has it's original CPU in it, too). If I can find more spare parts for cheap I'm definitely going to try to resurrect the remaining C16s, too.
That's my Wednesday morning break extended. I have good coffee and some cookie dough tart and Jan Beta.
On the first one, did you try cleaning the socket and re-seating the CPU before replacing it?
No, but I tried the CPUs in a good machine and determined they are gone.
You master commodore
We've just bought one too! Although its very much an underdog of a machine, I love it! Its useless really for games, but I still love it. Perhaps its the colour of the case?! :)
Yay! First to another Jan Beta Video! I wish I had a Commodore 16...
Did you know that Commodore originally intended to install huge, ugly looking single-sided PCBs inside the C16 to save a few dollars on product costs? I was really amused when I saw such a board for the first time (and so was Bil Herd, as he stated himself).
I use a Y adapter on my C64, that uses an NES and PSP power supplies, the funny part is though the NES actually has a built in rectifier but the power supply was actually AC
6:00 One should note that the original NES plug (in the US at least, i dunno about other releases) was an AC adapter and not a DC one so it can potentially fry other things that don't convert AC to DC internally after the plug if you use a NES plug in another device.
Yes, good point! Should probably have mentioned that. The European NES adapter I have is AC, too.
I had one, then I got a Plus 4 when I was a teenager. Then I created my own version of Geo's and databases and a game called Cliff Golf when I was like 11. With my Plus 4 I did most of that really only got into building databases with the Plus 4. By that I mean I built my own databases I didn't use the 3+1 I wrote them from scratch I did them in basic. The Basic was so much better than the c64's version. Eventually I got a 128D I never programmed in C64 only the 128 basic it was really good for somebody coming from a c16 style of programming.
maybe I'm stupid for wanting one. I don't think I am. Watching the various TH-cam videos most of them yours I saw some of the proper 64K games that weren't handicapped to run on the C16
Hey if you can hook me up I'll pay appropriately, I'll even take a Plus 4. I just remember getting a 1571 opened up a new world.
If anybody reading this has one and a 5.25 Drive I just wish, I can send money.
These things so valuable, especially their joysticks I used to break all the time with their custom connectors.
Maybe it's the processor, maybe it's the PLA, maybe for me it's the being Friday and the Bourbon.
I had Amigas, even the C128 was awesome. but I love the C16 and also the plus 4. I'll update the C16 to 64K so I don't want to ruin a pristine original machine - just a good one with all the keys and retrobrited keys ok. I hate to ask what a disk drive costs and the cassette why not.
but brennocks@gmail.com I'll throw a few hundred your way. I just want it for me, not for a museum piece or to resell for money.
As a young man I loved having the new model 1541, I think from memory it was a 1571 but maybe it was the 1541 II it was the new looking case on it.
I'm happy to buy one I'll do the 64KB mod I just wish
When I got mg C16 as a child it came with 2 games Xzap and Punchy which was basically a rip off of Hatchback. Good memories. 😎
I love Xzap, simple but really fun. Great sound effects too!
I love your video's, I'd never have the guts to attempt what you do but it's great watching you repair and salvage these classic systems.
I have a Commodore Plus 4 and would love to have a modern power solution for it, I ordered a C64/C64/Vic20 modern psu from Poland but I'd love to have a modern one for my Plus 4. Someone developed a USB power solution for the 8bit Atari systems and that's fantastic, it's a pity someone couldn't do similar for the Plus4. Any ideas?
Jan,can i ask what size "Chip sockets" you have used where you removed the original chips from the board please.Thinking of doing this myself to my C16 for the 64k RAM upgrade.Thanks ever so much :)
Fantastic video, I spent so much time when I was young on Commodore. Now Unfortunately on the display of my C16 after switch on there is only "COMMODORE BASIC V3.5" and nothing else apart the blinking cursor on the left top.. Any suggestion my friends
I had a C16. Also a Plus 4. But didnt do much with them. They got black screen disease, when in storage
Yeah, I think the manufacturing process of the chips was flawed so they degrade over time even without using them.
Hi, I saw your video and I have a question for you. The Diag264 EEPROM you had used on last C16 in video is bought or have you programmed it yourself from the binary file of the author? If was this case, what programmer have you used and what EEPROM? I have my first C16 with blank screen issue and now you have switch on the light of my hope to resurrect it. :-)
If you ever want to buy a new 9v 1.5-2A Center negative supply so you can have one that's of good quality that's not hacked together, There are a few models of Dymo label maker AC adapters that are 9v center negative at 1.5A or 2A.
Oh, interesting. Good to know, thanks!
welches kontakspray verwendest du?
One tip, don't leave those OK-tapes stuck to the case for more than a couple of weeks or you'll be sorry. Stick them to the bottom of the case if you really need them. The glue may make permanent damage.
Oh, they are not going to stay on there for long. No worries. Thanks for the reminder!
i never cut the cable to reverse polarity you can just open the power pack and switch the wires over, much neater and safer
Depends on the power pack. Plenty of them are glued shut
I'd cut the wire, reverse and leave a loop out on one wire for a current clamp meter hookup.
I actually planned on soldering on a new plug when I cut the cable but I didn't find one in my parts bin so I ended up doing it the messy way (as usual...). ;)
@@jaycee1980 i use a Dremel to cut them open when glued and re glue them after, i also install on off switches to while im at it.
@@JanBeta yeah that's another good way, but i tend to put a on off switch on the power pack at the same time so its easier that way
go to the computer museum in Zwolle in the Netherlands.amazing!!!!!!!!!!! i have 2 working cbm 64 comps with datarec and 2 power cartridges.not for sale.
I bet you could make a 'board washer' with a plastic tub and some creative use of cheap parts from China. Like maybe a few peristaltic pumps...
I know this kind of goes against the 'preservation' aspect of your channel, but I think if you would look into maybe documenting the 'hacks' that people used to do to these things, like the ram-expansion switch... That would be cool to see. I read about these hacks, but nobody has good video/explanation on them. It could be part of a series maybe?
I'm definitely going to look into the 64K expansion thing. There's going to be a video about that, too.
Wondering what good a C16? Never saw one till the internets came out. How many games were made for the c16?
LOL , ich geb dir mal nen tip benutze nicht das Teure IPA zum waschen sondern das günstige Brennspiritus welches zu 94% aus Ethanol besteht und ein paar vergälungsmitteln aber weitaus günstiger ist um es SO zu benutzen :) , und es tut den gleichen Job wie das teure IPA . Gute Arbeit und gutes Video by the way , weiter so ich schau die Videos immer noch gerne :) grüsse ausm Saarland
Vielen Dank! Spiritus hätte ich benutzt, hätte ich welchen gehabt. Der Alkohol kam aus dem Chemie-Großhandel, war zumindest nicht überteuer. ;)
That last issue looks like a PLA issue, mine did simular after being left on for a while.
Ah, I’ll have a look at that.
My north american C16's didn't come with the 64 style supply but more of the usual wall plug dc supply rated 9v 1amp which at least on mine so far hasn't been a problem. The +4 I have does have a supply similar to the 64 type but with a different square looking connector. The 64k upgrade is actually quite easy to do for anybody familiar with soldering. There is / was a 32k ram cartridge made available via commodore16.com a few years ago but haven't checked if its still available.
EDIT: the 4464 chips you used in that 1 C16 are part of the 64k upgrade so your not far off having the ram upgrade ready as you saw from the other 16 you had troubles with.
Yes, I want to do the 64K RAM upgrade soon. Interesting about the different PSUs. The one the German version has was pretty similar to the C64 (except it doesn't provide AC). Transformer and linear 9V regulator. Very prone to overheating because the regulator they used was slightly underrated for the machine. The Plus4 PSU is basically the same as the C64 PSU except for the plug. They actually made some Plus 4s with the round connector and sold them with C64 supplies here.
I have heard of other variations among commodores. What regulator did they use in those 64 style psu's over there? On the +4 what they did there using the 64 style connection actually makes more sense since over here the connector used was only used on the +4 so only place to get a replacement was from a dead psu.
Quick question, why do you try the chips on the unknown machine? Isn’t it better to try the unknown chips in a known working machine first? I heard it somewhere, what is your recommendation? Thanks
Hi Jan, the original Commodore 16 Power Supplies were, in my opinion, far better designed and more reliable than the C64 bricks especially as the C16 supplies had air vents :)
Good point. I think they are about the same design as the C64 ones electrically though. I'll have a look as soon as I find the one I have (somewhere).
Some versions of Plus/4 had similar shitty power supplies as C64 (with twin voltages, 9V AC and 5V DC), altough with square-style connector as C128. They are not compatible though. Modern power supplies are more reliable though.
Great job Jan 3 out of 4 is not bad at all. Were the cpu cheap versions or was it a design fault?
Thanks! I think the layers were too thin in the CPUs or something. There are better versions from the late 80s/early nineties which are unobtainium unfortunately.
The 1st game i ever played was scramble on the C16
Oh, don't know that one. :)
Center negative is still the standard these days for music/instrument gear like guitar pedals and effects and what not
Yes, I’m actually using the same power supply for my BOSS tuner sometimes. :)
is it possible to fix to a commodore 16 that you got the polarity wrong on
In a best case scenario you probably just have a broken 7805 regulator, worst case many of the ICs have died. I would measure the voltages on the chips and see if they are good and go from there.
Ironischer Weise hat der TED wesentlich bessere Grafikfähigkeiten, dad Nichtvorhandensein von Hardware Sprites waren ein Problem. Wenn die 246 Reihe dann noch einen dem Sid vergleichbaren Soundchip und durchgehend mindestens 64kb RAM gehabt hätten... Der plus/4 wäre wohl mein lieblings 8bitter 😁 (der schönste ist er imho ja schon 😅)
Ja, der TED ist ein sehr gut konstruierter Chip. Nur eben nicht auf Spiele ausgelegt wie der VIC-II. Es wäre vermutlich relativ einfach gewesen, die 264er "aufzubohren" und sie dem C64 weit überlegen zu machen, aber das war ja nicht der Plan der Ingenieure. Leider hat das Management das nicht so richtig verstanden... ;)
@@JanBeta japp, wie so einige merkwürdige Entscheidungen in der Firma. Z.B. der C16(übrigens der aller erste Computer an dem ich saß und spielte) und der C116(der viel teurer verkauft wurde als von Tramiel geplant) waren für den Plus/4 durch den geringen Speicher-Ausbau ein Hemmschuh oder die gut gemeinte C64 compatiblität des C128 war unten auch auch eher hinderlich. Beide Rechner Krankten daran, das die Software macht lieber Software für die kleineren Modelle schrieben weil diese ja dann auf beiden Rechnern läuft...
Die Amiga 600 und 3000 hätten imho schon so etwas wie AGA haben müssen, mehr chipram, eine Paula Nachfolgerin war wohl auch schon angedacht gewesen...
23:35 Isopropyl alcohol does have a strong smell, but there are definitely worse smells.
Yes, I actually like the smell really. In this case it was a bit much. Not much air circulation in my little lab. ;)
It was the C16 which killed the 264 series for Commodore. Nice work as always. I forgot the reason why Center Negative is used by some companies. It's not my favorite connection configuration but there is a reason for it and its bugging me I can't remember the reason why its used. I have a tablet which has a center negative connection I used it as a GPS and finding a supply adapter for my car was a challenge but I found one where you can switch between center negative and center positive and it scared the hell out of me each time I used it because switches can get changed so I was always checking it before using it just to make sure it was set right.
I think the reason for centre negative had something to do with connectors acting as switches. Can't remember the details but Dave EEVBlog mentioned it in a video.
@@JanBeta Actually pretty easy to find replacement centre negative PSUs for the C16 as they have the same power requirements as the ZX Spectrum 16/48k, Plus, 128k (Toastrack) & +2 Grey
Commodore C16, Sega Master System, Sega Mega Drive mk1
👍
If you have a failed PLA in the fourth one I made a video a while back on how to replace the PLA with an EPROM. It can be found here: th-cam.com/video/sG1e_b0julM/w-d-xo.html
PS: it was a Plus 4 but they are the same as the C16.
If you need the files sent to you I can do that as I currently don't have a way of hosting them.
You can fix the standoffs easily with Loctite.
Well, the c16 power supply has got 14 v. And the jucks of Commodore nobody told that this machine works with center negative. But one said something overheats the chips inside.
Ok, i must buy only a new power supply!
And then its done!
I think this was one of the reason the C 16 would lose on the market.
Play Squirm "it is a better version than the C64 version" I say better! it is just a nostalgic version to me.. My Brother had a C16 when I was a little kid and that game I liked and played a lot. You are lucky Jan having these Commodore 16's, I have been looking for a reasonable priced one for years as this was the first home computer we had before the Commodore 128.
Oh, good idea!
Hello! My older brother handed me his Commodore 16 in the hopes I could get it up and running again. I have no extremely ltd understanding of electronics. Is it safe to use the original PSU with our modern sockets (United Kingdom), or will some changes be required?
The original PSU is utter crap unfortunately (and they can destroy the system if they break) but you can use an off the shelf 9V DC PSU as a replacement. I’d recommend going with at least a 2A model. Just make sure that you get one with a center negative plug!
@@JanBeta Thank you very much for the reply Jan. Great video!
I have some 6502s (I need to test for 'goodness') in case you don't find a fitting CPU, it's probably a pain to adapt but hey, it wouldn't be the same video as Adrian's ; )
Oh, I have some spare 6502s here as well. Would be more difficult to adapt them I guess but I'll look into that. Good idea. ;)
@@JanBeta Huh, after some casual research ... it turns out this may be very difficult if not impossible. It's not just mixed up pins but missing lines...
So ein Teil hatte ich auch mal bei Quelle gekauft Nach 3 Tagen habe ich es wieder zurück geschickt .
Haha, ich vermute, so ist es damals vielen gegangen. Erwartet wurde ein besserer, eventuell kompatibler C64 und bekommen hat man eine komplett andere Plattform.
@@JanBeta Erwartet habe ich den besten 8 bit Computer und den habe ich auch bekommen.
Mit dem Floppy 1551 Disk Drive kann es der C64 nicht aufnehmen.
it's not 'the commodore 64 keyboard in gray'. the matrix is laid out differently. other 'simularities' between all cbm lines keyboards are just due to the fact that they're all based on switches and keycaps designs of a certain manufacturer that was popular at the time. and this is just an integrated all in one plastic version of such a pcb. (you'll find the exact same layout and key caps and all that in different colors on various other, more obscure, 70s and 80s terminals and microcomputers. just with switches, as they did not make a million of em ;) but it's quite clear that they're all just based on a pcb with switches in a metal frame type and are just a cheap mass produced drop in replacement for those. also not even made by cbm themselves but usually outsourced to other manufacturers. (where you therefore damn well could potentially place an order to make a few million more.. as they did not go out of business and probably still have the molds ;)
You are correct, it’s wired completely differently. I just wanted to point out that they went with the C64 form factor mostly. I doubt that Mitsumi (who made most C64/C16 keyboards still has the molds or data for the assembly). Although that would be a nice thought! :D
Yay, finally some more commodore stuff! btw: did you hear about the release of "The Commodore 64"?
Yes, I heard about it. Not of that much interest to me though. Might check one out anyway once it gets discounted a bit. ;)
Well i think they should give you one to test it. Who else should have the expertise to do such a test but you - beside the few usual suspects of course...
@@madmartigan1498 I wouldn't mind that at all. Maybe they will, didn't hear from them yet though.
We heard.... It came out in 1982, your a little late. Lol
Excellent work! Maybe I should send you my Plus 4 to look at? Never turned it on, but somebody butchered it before I got it. see TH-camr Adrian Black, he did some interesting C16/Plus 4 repairs including using a 6510 as a 7501 replacement and a PAL/NTSC Kernel ROM Switcher.
Thanks! Yes, I followed Adrians videos, very nice work. :)
4 x 16 ... you almost had a 64 there.
You're right! If I fix the last one it is going to become another computer. :D
Just put 4 × 16 into crafting table and boom! A 64!
53:20, Where did you touch Ted? :D It's no wonder he's going a bit funny! haha
Just watched this again after putting a C64-type power connector on a Plus 4 - worked great for five minutes but now failing with black screen (painful experience that was!). Unfortunately I don't have multiple machines but the TED chips are cheap, I have a modern PLA from a C64 that can be set to 264 mode (tested with this, still black screen) and I've ordered a 6510-to-7501 adapter for the CPU. If it does turn out to be the CPU I think I'll be either getting a new 6510 or adapting a 6502 to work on this - no way am I paying ebay scalper money for another 7501 that looks as if they (almost literally from this experience!) fail if you look at them funny!
If course in my case it's bound to be a bad solder joint or RAM failure - sod's law! Don't think there's a dead test for these is there?
My childhood computer! Nice job getting some working machines from that lot Jan. I had same common problem, faulty CPU and it actually went faulty in front of me lol. I got a second machine that had issues taking a chance that the CPU was OK and replaced mine with it, so nice working machine for me. BTW did you notice the factory mod on one of your boards, I think it was the one with the RAM mod? I have the same thing on my "donor" board, at first i thought it was a bodge job: th-cam.com/video/KB4ed1YeX3Q/w-d-xo.html
Still convinced you are Jurgen Klopp's brother.
Or maybe even Klopp himself. Maybe you could restore Adam Lallana to his former self.
Shhh, don't tell anybody!
Commodore 16/Plus4 were quite underrated. I never understood why Commodore decided to give it such crappy sound in comparison to the C64, a total lack of sprites and hardware scrolling. They did give it a color palette of 128 colors and a proper Basic, which is odd.
It was designed to be a budget business machine so they didn’t put in "gaming" features like sprites and proper sound. Still an amazing machine.
Yeah, they are still amazing machines.
Weiss jemand wie man die gebrochenen Leertastenclips für C16 repariert? Ich meine die Dinge wo der Metallbügel unten einrastet.
Wenn du das abgebrochene Teil noch hast, kannst du versuchen, es mit einem Modellbaukleber (ich benutze UHU Plast Special) wieder anzukleben. Ansonsten ist eine Möglichkeit, es mit Sekundenkleber und Backpulver/Backnatron zu rekonstruieren (da gibt es einige Videos unter dem Suchbegriff Superglue and Baking Soda).
@@JanBeta Danke ich versuche es und berichte wie es ging.
Die Reparatur lohnt sich nicht wirklich. Da ich den c16 sowieso nicht brauchte (habe einen c64) habe ich ihn einfach so weitergegeben.
Round holes are better for round pins
=====> O
Amazing how many of the CPUs are failing on these machines. Did CBM deliberately overclock the things past their tolerance in order to make the machine's performance bearable against the competition?
What is being written is that in 1983 and 1984, Commodore were using too much boron in the production process and this causes the dies to self-corrode. There is nothing you can do about it except keeping the chips at low temperature. This is also the cause of the high failures in Commodore 64 PLAs. PLA form the bad years die in fleets, the ones with good production dates are reliable.
00:59 - the colour of those keys...YUCK!!!
Can you put a C64 in that case? I like that case better!!
I think the PCB fits but you have to slightly change the cutouts for the connectors in the back.
Wait, is it... a Commodore machine that knows other colors besides the shades of blue and green??
15:20 They are called single wipe sockets. And yeah they are garbage.
Ah, yes! Didn't remember the correct term, thanks!
Jan don't forget to heat sink the Ted CPU and PLA as this will prolong the life of these valuable ICs mate .....and I have a CPU mate 😁😁😁 DM me on twitter if you are still looking for a CPU mate. Great vlog Jan 😁😁😁 Kim 😁😁😁
Kim, thanks! I put heatsinks on the main ICs in the C16 I want to use as my daily driver. Also going to do a 64K mod sometime. I'll send you a DM later, still looking for a spare. Would be great! :D
Hm. Let’s see, which Games I remember.
BigMac
Auriga
Winter games
Paperboy
Mercenary - you need 64k for that. Come on, do those puppies a favor.
Winter Games on the C16 was superior to the C64 Version, no kidding. Loading from tape was pain though.
I'm quite partial to Xzap and Timeslip
Nice, I'm going to check those out. A 64K hack is on my to-do list as well. :)
You have 4 x Commodore 16.......or one C64 :P
My favourite games on the C16 were "Ghost Town" and "Tom" from the german developer Kingsoft. Other games by Kingsoft were also very sophisticated. I always was stunned how many colours the C16 was capable of displaying. - BTW: The worst game that I ever bought for the C16 was "Ghosts'n Goblins". It was so bad that you absolutely must have seen it. It is easily the worst arcade port of the millennium.
Haha, I have to try the good ones and am also going to take a look at Ghost'n'Goblins... :D I'm a huge fan of the stuff Kingsoft did for the Amiga, too. Definitely going to check them out on the C16.
Some people avoid cheap or old ....................................
**JAN** what became of the modded c64?
The Thundercats themed one? I use it for streaming on my Twitch channel occasionally. Still going strong. :)
But what a bad luck !! all these computers is nobody who has the same problem as me. I have to search again.
Oh, sorry to hear that. What is the problem on yours?
@@JanBeta On the screen I see vertical craete lines with the "@" character and at the bottom some interference that seems to flash at the same frequency as the cursor. Unfortunately I have a broken plus4 and its components even if put in the C16 didn't work.
tutti frutti - its fun to play, honest!
Guten Tag, Jan Beta du kommst doch aus Deutschland oder ? Machst du Reparaturen für Kunden ? Könnte ich dir mein C64 zusänden mit Bar Geld darin ? Ich glaube das der PLA Chip hinüber ist. Der C64 hat ein Schwarzes Bild beim einschalten. MfG
Instead of marking broken processors with an X, put them in the bin.
s/bin/display
I don't have a dishwasher, she left years ago. Lol
I'm my own dishwasher. ;)
@46:38 Nooooooooo, don't pry up the chip ! you can cut tracks & tear up pads. Wiggle it back & forth with the plane of the board using your thumbs, sort of like this -> [ ]
