My Amiga 1200 didn't let me down, I did. Replacing capacitors I didn't need to
Why has the sound become weird and crunchy on my A1200? Is it because all A1200's have failing capacitors? Well...
In this video we recap an Amiga 1200, and then find out what was really wrong.

My old tech - Laptop attacked by battery acid, our old Canon SLR
Intresting video, I found a T2100 in a skip a few years back and it did turn on but I just put it in a draw and forgot about it until today when I tried it today was dead.I took it apart and it started to work again. The battery is dead but works from mains. I do see 6 files when I type dir windows,office ext. The laptop only seems to boot to commandline should it boot straight to windows or do I need to type a command. I'd like to see it working although I have no real use for it.
I played hours upon hours of this as a kid! It should be running much better with a pentium. If you were running it from windows, that probably sapped a lot of performance.
Subbed! Great videos. They've been helpful so far for disassembling one I'm trying to fix. I think I may have a similar PSU issue and am trying to find the schematics to identify all the capacitors on the PSU and motherboard (or at least the PSU), can you point me to any resources online - so far I've only found forum discussions but no documents? For example what did you replace out on the PSU? I could start there. Thanks!
I've added my notes to the video description, the spreadsheet has a tab for PSU and motherboard capacitors, it's mostly complete for the PSU, and has some links to the replacements I chose. Though I don't know if those links will still work. However I think there may be more than one revision of the PSU so be careful, I just read all the values off the capacitors!
Thanks for the help. Looks like it is the PSU capacitors as disconnected from the motherboard it's still looping with a climbing high pitched sound. Will get them replaced and try again. Cheers
@@hamiga2570 Ah interesting, I think it does have a 'ready' signal from the motherboard, so it might still do that disconnected? Though I don't think mine did.
Most people might struggle to isolate & identify bad caps. So a complete recap is their best bet.
have you recapped your 1084s?
No the insides of CRTs give me the fear! I have the 1081, it's Amiga branded which I haven't seen so much.
the music is so loud I can barely hear you.
Good to know, I'll tweak it a bit in future
You say replacing capacitors you didn't need to but its a well documented problem and isn't is easier to replace them now before they leak causing problems? You did a good job with it and as you say that's it now done for many more years use.
It's definitely nice to have it done, always difficult to know with preventative maintenance if you 'needed' to do it yet!
These caps don't see much wear or high temperatures unless there's a 040 or higher accelerator and mechanical hdd in it. Still can't hurt if you don't damage pcb and bridge pins etc. My first thought was to check voltages with an oscilloscope. That would've pointed you towards psu issues. I suspected the opamp. Also consider getting low melt solder, it makes it much easier to get stuff out with large pin counts without damaging the pcb. All in all you did a good job!
Oh can you use low melt solder to help melt the existing solder to remove things?
Yeah, sadly changing capacitors has become an internet meme. Everybody is doing because everybody else is doing it and not because it needs to be done. It is partly understandable as there was a short period, the late 1990s to early 2000s, when capacitors were being made sub-par and bad cap syndrome was a thing. Your Amigas, and many of the early home computers, are from a period before this time and clearly have decent quality caps. I see too many TH-cam videos of people with very poor soldering skills replacing perfectly good capacitors with ones of dubious quality to end up with a computer of worse reliability than when it started. Capacitors do fail, dont misunderstand me, but this blanket change mentality is bad.
It's tough to know where the truth lies. I did have some sympathy for the idea that these marked the change from through hole to surface mount, and that might mean they were new and risky at the time.
I recapped my “spare” A1200 the other month. All went well except a THT lost a pad. Very annoying but I rescued it. Didn’t fix the underlying poor video though. And then I broke the clip holding the space bar’s bar on. Very annoyinng! I used two layers of aluminium tape and hot air to remove the SMTs near the keyboard connector; much easier IMO. For my “baby” (purchased in 1992 when I was about to start uni) I didn’t chance it and limited my surgery to fixing the non existent sound output. Turned out to be the quad opamp IC. Swapped it over and she sounds just like she did when new. Retrobrighted her too. Just went very very easy on the plucking the keys off this time. It’s great having her look great. I even found one of my newish Dell monitors does PAL and multisync, which is absolutely fantastic for workbench and games via WHDLoad. Hope you are keeping well!!!
Oh that is some good luck finding a monitor that works well! Doing alright thanks, now I can treat myself to opening up my new thrift store purchase.
Well, it seems like stretched drive belts on these Toshiba drives is a common issue. I have my Satellite T2110 in parts on my workbench (your previous video was very helpful here. Thanks) and I have the drive out. The belt is very loose just like yours. Can you perhaps tell me what size belt you used so I don't necessarily have to order all of them? Also, where did you order them from?...finally, did you consider trimming the belt down so it wasn't so wide? Cheers
I am not sure where I ordered from, but I just searched 'tape belt' on Amazon and there are plenty of options. I wasn't sure how to measure it well since it was stretched, so that's why I bought a variety. The reason mine had fitment problems is that the belt was 'square', so it's not that it's too wide, it's too deep / thick. I see some of the variety packs have both square and flat belts, I bet flat is what's needed. Maybe I should try again! Good luck.
Hello. I am wondering if you could help me or if you know someone who can. I have the same computer, except that when booted the screen does not work at all. Thank you so much!
Do you mean the screen works when you power on, but not later? Or not at all? It would be hard to troubleshoot, though the first step would be to check if the power supply to the screen is good. It's high voltage, so if you haven't used a multimeter before this probably isn't a good one to start with.
@@mattsqwrl The computer powers on normally, you hear the hard drive run, and the start up beeps but the screen is completely unresponsive, blank as if its powered off.
@@KazukiMatsuoka It's very tricky to troubleshoot this old stuff. It does have an external monitor connector, but you'd need some weird old monitor to use it. But that would let you see if the rest of the computer is doing anything, though a beep is a good sign. Checking the power to the screen with a multimeter would be the first step, it comes from a red molex connector iirc. But also it's 200v, scary stuff.
@mattsqwrl this is a project that myself and my Father are doing together. I was born in the late 90s so this is exciting for me, Dads an electrician so he can start with that monitor. We are looking into getting a CGA to VGA adapter. Thank you for the input!
lemmings always sounded like it was playing a tune when the floppy disk was been read
Do you know anyone who can repair a power supply for one of these?
I am afraid not, I have just been lucky so far and had working stuff, or they needed fairly simple fixes. I think some retro computer museums offer repair services, or might be able to point you in the right direction.
I can't believe your original hard drive works. That NEVER happens in these.
I actually have a few working 80s disks, I have a Portable 386 which is missing the (custom) RAM so it doesn't POST, but it works enough to show an error, and I took the disk out and that's good too! I also have an Amiga 500+ with a working drive. It's got a few bad sectors but it's stable for now, and I've used it for more than a hundred hours without issue. I checked out your video, lots of ideas in there for me, and sorry to hear it stopped working! I'll drop a note in the comments there too.
@@mattsqwrl Well thanks to your video I was inspired to pull the CP3 off the shelf and take another shot at it. I didn't have enough caps to replace them all but the ones I did were apparently enough to bring it back to life! I even came back to this video to reference the motherboard power connector pinout. So thank you!
@@PixelPipes That's great, they're such cool machines!
You got some potential right there keep it up you can make a great TH-cam career in the future.
Thanks, and a bunch of people like you make it a positive space to be in.
The Amstrad word processor is pretty cool. It's one of the very, very few CP/M machines with bitmapped graphics. There is a bunch of games for them.
I'm pretty sure Apple had monochrome LCDs past this time frame in the duo line. Frankly, I would take a good monochrome screen over a low end color one any day of the week. Early-mid 90s Dual Scan color screens are horrible. Even at the perfect viewing angle, they absolutely suck. Though, to be fair, this is not a good monochrome screen.
You could try one of the pre-dos operating systems like CP/M-86 on it.
It's the Thanatron!
In 1995, Apple introduced the PowerBook 5300 - latest-and-greatest PowerPC processor roughly the equivalent of a Pentium - with greyscale display. 5300cs (DSTN), 5300c (TFT) and 5300ce (800x600 TFT) colour versions were also available, but I suspect the 5300 was the last grayscale PowerBook (along with the 190 sibling; same form factor, with LC040 processor). It might have been on the market for longer than that Toshiba?
Good video! Most people just go straight for the nearest CompactFlash / SD adapter rather than even try to deal with spinning rust hard drives anymore. I do like that yours has a more era-appropriate amount of space on it! Most usually have a few GB's.
Hello and welcome. Please provide a link to purchase these spare rubber bands.
Otherwise. Are tape recorder belts suitable?
Where did you buy those spare rubber belts?
It was a couple of years ago on eBay, if you search for 'tape drive belts' you'll see a bunch of options.
I have Compaq’s last laptop with a monochrome (it’s a TFT) display, the LTE Elite 4/50E. It’s as rare as this Toshiba.
Some nice Compaq's on your channel! I have a Portable III and 386, but the 386 has no RAM in it and it's a weird type of RAM. I wonder if new ones could be made if an existing one was stripped and copied!
Are you a furry :(
This looks to be grayscale to me, not monochrome (1-bit).
Yeah it might be 8 bit grey or something like that, I went with what the adverts called it in the mag.
I played Wolfenstein 3D on a mono screen in the 90s.
I looked at your subscriber count and audibly gasped! You need more! This is awesome!
new subscriber :3
by '95, the only place people were still willing to tolerate a mono screen was on a Pocket PC. The question for a notebook was Dual Scan or TFT? I have a couple of Toshibas from the Pentium era and they both have TFT screens. For those who don't know, all modern displays use TFT (Thin Film Transistor) technology, whether they are VA, TN or IPS. Some major nostalgia here; I lived in the UK at the time. These days, a basic laptop might be desirable for a writer. Could use the floppy to transfer files to a modern PC via USB, although most of the external floppy drives are so old, they won't work with Windows 10 or up. Linux might support them. A better choice would be pretty much any slightly newer laptop with a USB port. There are modern Linux distros that are made to work on 20+ year old machines. I think an e-ink display would look and perform better, lol.
The high pitched whine should be coming from the LCD - there's a failing capacitor on the backlight inverter board. Search for UA0392P01 capacitor for more information and pictures. C3 is the one that needs replacing and it may have leaked so electrolyte & corrosion will also need to be cleaned up.
I had one of these! Prior I had Compaq Aero 4/25 and later on a few IBM Thinkpads.
If netbooks had come 10 years earlier, they likely would’ve been monochrome 386’s… in 1997
The Brother GeoBook NB60 from 1998 was the last monochrome laptop I remember seeing. It has an AMD 386 CPU and runs GEOS, but can also run DOS software.
That is a very strange computer, I kind of want one.
im my opinion, i would never replace a HDD if that is not Broken. Keet the Hardware as Original as Possible.
Same, this is actually the first retro machine I've had to do it. Old disks are more reliable than I would have guessed.
I think my mom had that thing as a 486 sx 25
Such an interesting computer! I’m actually jealous, never seen such a laptop in such good condition 💫
Thank you so much for this video. I have the 265 and the foam headband is toast. I can't find any replacements and your video showed up! What is this web link? Looks foreign I'm in the USA.
In those days there were many Toshiba laptops extremely cheap from second hand due locked BIOS, password not stored in CMOS on RTC battery like classic AT board. Doing shortcut in some LPT pins BIOS was restored to factory setup - profit 💰

It's ok because it's a halogen hob, so what's the worst that could happen!

It would be awesome to see how a period correct Linux distribution would have run on this. I didn’t get into Linux until 1997, when Pentiums were current, but I’m pretty certain a few people would have run Linux on machines like this. My first laptop was a Tecra, Pentium 75 IIRC. It was ex business stock and obsolete in 2000, when I got it. Bloody hated it and was so much happier when I switched to a, again ex business, Thinkpad. It’s the build quality on those Toshes which let(s) them down. Thanks for making this video and I hope you are doing well!
Yes same for me, a second hand Pentium 75. I still have it, it's the TI one falling to bits in this video! Doing ok but it's been a busy year. Any idea what a period correct Linux would be?
Ah yes that's giving me flashbacks to the first two times I tried to install Linux. Once I booted it from CD, and it told me I had no CD drive. The other time it claimed I had no hard disk.
