can it run crysis?

Looks like a great device!!!

Fun board. Always love me some blinkenlights!!

Amazing tool Rudy. Thanks for such a comprehensive video.

What a cool tool! Thanks Rudy!

Very cool device Rudy!

That is really neat Rudy

I was bracing myself for a long, arduous c64 repair after it was seemingly suffering heat damage back in like 2014, but powering it on last year, everything was perfect running on a modern PS replacement. Still, ome of those for c64 would be useful to diagnose my 3rd if I get into a repair spiral later on

Here something. Put a slot on the diag card outside the case so you can plug a card into it from outside the machine.

Love IT!!!! Well done.

Wow Rudy, this amazing!!! Excellent work my brother 🎉🎉🎉🎉💪💪💪

Late to the party here - about to do this myself so thank you for the video. By the way the video from the Apple II looks awesome. What is your video setup?

Thank you Rudy, this is a very comprehensive and informational video!

What about an adapter board that would allow the use of DDR1/DDR2 RAM modules.

What about a 65F02 which is a FPGA version of the 6502

I have got the kit to make. A very good way with the resistors, I will do the same, I got a cheap oscilloscope of Ebay a DSO-TC3 Oscilloscope. For me its ok I hope to use it not alot.

Really nice diag card, especially love the scope point too...... nice

That is indeed a pretty diag card, always love the blinkin' lights!

Neat diagnostic card! Looking forward to learning more about it.

Great job Rudy

I built a very similar board also I use for testing but not show or released it..... Awesome video Rudy!!!

Hello Rudy! Well, it's a "vexata quaestio", hard to answer 😀. I mean, if you receive an old computer as a donation vs buying it. I have one Vic 20, but with spares in case something goes wrong. C64, I own 4 and a spare board; one bought and the others donated. Commodore 128. ehr... 4, also an empty case and a spare motherboard. I think that until you doesn't try to get EVERY computer it can't be called hoarding 😛. Thanks for the video 🙂

Nice review! As always it seems Im late to the party......Out of Stock!!!!!

I love your Juki 6100!

I instead got an a2heaven VGA daughter card for my RAMWorksIII. Although like you I am also intending to get setup with HDMI-out. I picked up an OSSC off ebay and will be trying it out soon. I'm wanting it to also mix audio out from my Phasor card and hopefully I can get those to sync correctly with the right settings on the OSSC.

7:25 This card was pretty expensive back in the day. There is a review of the card in creative computing from Jan of 1984. This is taken from that review: "The Appli-Card presently lists at $375. It is also available, bundled with WordStar for $500 list--good value if WordStar is the word processing program you want. The RAM Extender is another $200 or so, depending on whether you get the 64K or 128K version. The 64K version is said to be upgradable to 128K by the addition of eight 150ns 4164 chips, at a cost of about $50. " For this 375-$500, you really still have to add an 80 column card. It can do a 70 column display without the card or a 255 character "scrolling" display (meaning the screen is a window to a much larger screen). If you want to do word processing well, you need the 80 column card. Though I think using it for a spreadsheet, it would be better to use the 255 column scrolling window. Plus it has a bunch of compatibility problems. To get it with single useful application for $500 is not affordable. Plus, this is 1984! The writing is on the wall for CP/M at this point.

5:00 According to the manual, it's a 300 baud modem. The first 14.4 modem came out in 1991. This thing cannot do anywhere near 19200. It may have a serial controller that can reach 19.2, but that is completely different.

Please don't ask these difficult questions LOL. I do have a solid double digits worth of Commodores, same for Atari, but only about 4 PCs

Three: One of mine (TI-99/4A) is practically new in box, another one is not but in okay shape, and the other one looks very rough. It turns out they all work, but I collected the two not new ones at the same time (one for backup) then found the NIB one later. CoCo 2 never been used NIB, stays that way since the CoCo 3 does all the 2 will do... I say you can never have enough spares LOL... Well, depending on the longevity and rareness of the machine.

If you use them then it's not hoarding. On the other hand if they are just cluttering your space then it is hoarding (by definition). I would probably fall under the category of hoarder because I have acquired more vintage computers than I have had time to repair or even verify properly. I do like restoring these systems and want to spend time learning each one but I do find it difficult to resist a good deal when I see one. Currently my vintage computer count is at 99 including several pocket computers. This count does not include all the peripherals nor my calculator collection. Out of the 99, I have 76 verified working systems and the rest is a mix of faulty or unverified systems. I have yet to resell any of my systems but once I am satisfied they are in good order I will probably thin down quite a lot. For example, I probably don't need any Tandy Coco 1 and Coco 2 when I have working Coco 3s.

Great question. For me, and I'm very tight for space, I'm just 1 and only machines that I have a strong attachment to (or as v small 😅). I think if a machine dies you can worry about it then, but not too much before.

I ended up with 4 VIC 20s, 3 of which were bought “not working” for the peripherals that were included with them in the auction. I intended to use the extra 3 broken ones for spares but all were really easy to fix (2 just needed deoxit in the power switch). I will sell/swap 2 of them, but I haven’t got round to it yet because I still have to renovate the tape drives that came with them.

To me its all about the intent. I have a large number of C64s from the Stone Collection but they are here to be revitalized and moved on to people who will enjoy them. One went out just yesterday.

Now that's a really great question. I have large enough collection myself at this stage (along with an Apple II, Thanks again Rudy) and I've wondered the same thing. The way I see it, it's the custom chips that you need more so than second units in very many cases. Take for example the C64, all of it's custom chips, The Vic 2, the SID and even the 6510 can be bought as new (through the use of FPGAs and the likes). So for a system like the C64 the question is, do I want all original parts or will modern replacements do me? If you're happy with modern stuff then one C64 is all that you need. All you need in stock for the Vic 20 is a working VIC chip (the only part that's not currently available) and the same applies to many old systems. Personally, I'd prefer a small stock of custom chips that are hard / expensive to find and repair the systems that I have if and when they go bad. At the minute I've got a sick TI99 4/a, an unwell Vic 20 and my MO5 has keyboard problems (so I'm trying my hand at PCB design). I'd say keep a small stock of what counts chip wise, save space and keep the collection smallish (I say with over 20 systems) that way you can give each and every one the love it needs. A great question well worth thinking about ;)

Such a problem to have Rudy LOL 2 of each is good

I think having at least two of each is not really hoarding, ten might be extreme. It’s always great to have a backup. Nothing takes the wind out of your sails more than wanting to do something on your retro machine and it suddenly doesn’t power up. Now you have to troubleshoot it and possibly order parts before you can get back to your original task. It’s also very useful for troubleshooting more failure prone machines like Commodore 64. Until I obtained two C64s troubleshooting was very difficult and time consuming. Sometimes you even reach the wrong conclusion and end up ordering an expensive part when it is not needed. With two machines, you can often swap out chips between them and narrow down the issue very quickly. There are also different features between models that you might like having. You could keep a NTSC and PAL C64. Maybe you have a IIGS with different ROM versions. This way you can run certain programs that are not compatible with the other variant, or even write code and ensure it works across both. The final thing is that we are all interested in preserving the hardware. We all love these systems so keeping them in our possession and out of the trash is a good excuse to have extras!

2 each is reasonable. It is also very useful for troubleshooting

Video audito cable for the ti-994/a is the same as for atari 8bit, vic20 - 5pin din. They are easy to make and/or available at 8bit classics

The only computers I kinda do this with is my Mac Plus, where I kept my childhood one and got an extra platinum one back in 2005 or so because it would seriously bum me out to not have access to a working one. I'd like to do the same with a color classic to help repair my first one from Japan. As for building a Weecee, I did 2 because it made more economic sense and I was able to keep a 2nd for future trade or gifting or backup for the 1st. Apart from that, time and space doesn't allow me to do this with the rest of my collection. One thing that'd make sense is your idea of 2 units, but do it with other people so that you're not forced to carry 2 units per person but rather spread it out with people local, or at least in the same country as you

In CP/M the PIP name stands for Peripheral Interchange Program. This program was used for copying files in CP/M. I used the CP/M operating system on a Heathkit H89 computer during the early 1980s. It is interesting to see that this very old and bare essentials operating system originally written for the Intel 8080 cpu is still in use and has not completely disappeared.

Hello Rudy, I have a kaypro II and no disks. But I have a gotek with flash floppy. I would like to use your file from GitHub for the CP/M and then copy them to a real floppy disk in drive B by using the gotek in the kaypro. Do you have also the right jumper settings for the gotek for me? Regards, Ben (From the Netherlands)

Is there anyone out there, who has a 6522-Card for the Apple ][? I built one -homebrewed- in 1983 with a 6522 and a Hyundai HY6116P-15 CMOS static RAM on it, but I can't find my documentation about this card... I know by sure, that I don't constructed and designed it by my self, I've copied the card from somewhere... The other TTL-Chips on this card are: a Bus-Transceiver LS245, and a LS74 FlipFlop and some other NAND, NOR-stuff... Best Regards Georg

I have this up and running, sort of. The video quality is still a little poor. Do you have a link to the rgb2hdmi settings you use? thanks!

Nice repair video. Thanks for sharing!

I also "race" my BASIC programs. I do it on emulators, not real hardware. PC-BASIC always wins, of course. I wish i had the skills to build something like this.

Nice video. Pleased my PET ROM/RAM, PET Diagnostics and SD2PET were useful. One note, although the 2001-8 cannot normally support BASIC 4 (as it does not have enough ROM sockets), you can use BASIC 4 with the PET ROM/RAM and it runs fine on the 2001 board.

Rudy are the STL files for those 2 items you added available? The gotek mount and the drawer insert?

Great work Rudy! Always love seeing you work on these. And I wouldn't mind if the video was 4 hours!

Lol that smile at the beginning

Great job Rudy your pet is super once more
