Watch me trying to repair a 1987 Amiga 500 board that was pretty much butchered by the previous owner. All socketed ICs were obviously ripped out with a screwdriver and the PLCC socket holding the FAT AGNUS was broken. Will I get this one working again?
Here's the follow-up video about the same board (some more issues with it): • "Butchered" Amiga 500 ...

Thanks for the video. It has helped me a lot, in bringing a Rev5/kick-1.2 machine back to life. I took notice on the fat agnus issue, and shure enough, one of the pins on mine had a thick layer of black corrotion. I moistoned it with IPA and scraped it off with a screwdriver that is as thin as the legs. Cleaned again and reseated. Then it sprung back to life with a glorious 1.2 boot screen. And then I used some 3 hours to clean rust from the plastic bottom-case. 50 percent was covered in rust from the shield. And some I had to scrape a thin layer off the case inside, as the rust had buried down into the plastic. 33 percent restored. Took 8 hours so far.

I am hoping that the PLCC mount in the A500 is the same one that houses the Super Buster chip for the A4000, I think it is. I followed the recommendation that if you are careful a screwdriver can work with this socket; however, I do not know how a screw driver would ever work with a PLCC socket, for I was careful and the brittle socket cracked instantly in the corner while trying to upgrade to a 1 meg 8372a chip, for I live in Canada with a revision 5 fat agnus and the 8370 and I wanted better Pal compatibility with the new ACA500 Plus. Anyway, I have ordered a new socket and the proper socket remover on its way from Europe...I just hope I can de-solder and replace the socket half as good as you have done. You have a tremendous touch with these very delicate and often stubborn components. Great video...I will be watching it again while removing my old PLCC socket, which hopefully will be soon. Hej då.

I'm tempted to just buy a broken Amiga now, after seeing you fix a bunch of them. I sort of want to spray paint the case of my Amiga, but I don't have the heart to modify the machine my dad got me back in perhaps 1993 or 94. If I got a second one that isn't working, I could simply fix the main board (ehm, "simply") and sell it, while keeping the case.

I actually also burnt out those 2 resistors on our Rev 5 board back in the day. I was trying to connect it to our old TRS-80 Model III using a null-modem serial cable that had all 25 wires connected. The Amiga 500 supplies +12V and -12V on pins 9 and 10 (of the DB25) respectively via those 47 ohm resistors. The TRS-80 serial port didn't use those pins, but unfortunately instead of leaving them floating, it actually grounded them. This meant 12V across those resistors, which is around 3W which is far greater than they could handle. I suspect the TRS-80 wasn't the only computer/device that grounded those pins, hence why you'll see those resistors burnt out on many Amigas.

Those two burnt resistors - what may have happened is that the previous owner mixed up the cables between the two data sockets on the back. I did this when I was a teenager and managed to connect one socket to the other - the machine was smoking, but fortunately my dad repaired TVs for a hobby and managed to fix it. Those resistors may have seen the same fate.

I always look for my old A500 rev 3 board I sold on ebay. Can't remember if it had a broken Agnus socket (I need to locate the photos I took for ebay)... But I do know the Crystal OSC had been removed... not sure if I put it in a socket and put it back or not... It also had jumper pads near the Agnus and the Trap door slot cut/soldered to complete a full 1mb of Chip RAM modification. I believe I sold the old board with an A501 expander (512k) which had its battery removed and an attempt to put a coin socket batter inside. I think I did damage my Agnus socket back in the early 1990s before I learned how to extract them better.... possible I put the old 512k one back in instead of the 1mb one. My A500 was set up to use the A501 expander, and one of the MegaChip's (DKB with the 8372b).... bringing it to 2mb CHIP RAM. I believe I put a M-Tec 68020 board in it (with 4mb of 32 bit RAM). I wanted to pair it with a M-Tec AT (IDE) Hard disk controller with 8mb of simms inside... But I couldn't understand the German instructions fully... I'd get the hard drive formatted but it would never show. So later I swapped it (from Software Hut or Devine.. or Grapevine... one of those mail order companies) with an Expansion Systems IDE/SCSI Combo and later added the 8mb RAM card. That brought the system to 14 MB total on an A500 with a 68020 ! Shame about the M-tec AT controller though... later I realized all I had to do was copy " Disk.info " to the partitions I had made and they would have shown up on the WB Screen... Sigh. A simple mistake. But it was still a good idea to pair up the two M-tec products together.. and THIS board is best to use a Megachip 500 on ! The other two, the rev 5a or 6? and the A500+ might be better to use a 2mb Agnus in the socket as long as you have 1mb of RAM in the trapdoor slot to finish the 2mb CHIP RAM limit. If that board above had damage to the Crystal OSC and there was any signs of the traces cut near the Agnus or the Trapdoor area... it could have very well been mine at one point. Although I don't recall the burned resistors ... Also, it looks like three more resistors are missing near the Paula and Gary... Which I know I didn't remove.

Great job! =D I had to do the same thing with my last 500 that I repaired. People ruin those PLCC sockets by levering out from the corners =( With those 2 resistors, you might find you've also got a faulty MC1488! In order to test that you would need to use the serial port with something - but they are hardly ever used anyway.
@JanBeta
@JanBeta 7 жыл бұрын
Thanks! :) This actually went way smoother than I expected considering what shape the board was in (I did quite some cleaning up on it before shooting this). Thanks for the tip with the serial port. I have to test it some day but I don't have anything to connect to it. Maybe I'll try recreating the serial loop cable that originally came with the Amiga Analyzer software and test it with that sometime. I kind of hope the previous owner "only" shorted the serial port power lines somehow. ;)
@GadgetUK164
@GadgetUK164 7 жыл бұрын
It's not uncommon that when something shorts out on the serial port that the MC1488s fail. I used to replace a lot of MC1488's on various types of equipment for that reason. Although as you say, it might just be the VCC pin shorted to ground. Although looking at schematics I only saw one resistor for the VCC rail, so why two resistors burned out if odd. Any idea where the each connected? I should look more at the schematics really :P
@JanBeta
@JanBeta 7 жыл бұрын
I probably should take a closer look at the schematics myself. All I read is there are +12 and -12V on the serial so I was guessing that the two resistors were for these two rails. I'll definitely have a closer look some time.

I am wondering what burned up those resistors?! They got SMOKING HOT to burn up like that. This means a lot of CURRENT flowed thru those parts. The Amiga 500 is my second favorite Amiga model, I have 6 of them in their original boxes and many loose ones. So, I am always happy to see another one repaired or saved from the trash. The Amiga 500 blows the fucking doors off the Amiga 600 and 1200 as far as quality and design. Also, the Amiga 500 is the most popular and number one selling Amiga model, followed by its big sister, the Amiga 2000.

There's quite some "juice" on the serial port (+/- 12V). My theory is that the resistors burn very quickly if you connect something wrong to the port so it would rather be a "user flaw" than a design flaw. ;) There's quite a few flaws with the earlier rev Amiga boards in other places, though.

If the power LED blinks in intervals, it might be an error code, otherwise it just means that the Amiga can't finish the Reset routine and is stuck in a loop. There's too many possible faults to list here I'm afraid... I would start by reseating socketed chips and cleaning contacts. I found that a lot of faults on A500s can be resolved that way. As for the drive, it might be a leaky/shorted capacitor on the drive PCB. It might also be the CIA chip closer to the drive that is faulty. You can swap the two CIA chips to check. If the drive starts working with the chips swapped, it's the CIA.

What happened to the power LED? It worked up until the rainbow arts logo then went out lol

+RefractionPCSX2 The power LED and the audio hi pass filter have the same address, so when the filter is toggled (many games do it), the LED is also dimmed (or in the case of the older red LED model A500 is turned off altogether). Kind of irritating but perfectly normal behavior. ;)

Jan Beta ahhhhh fair enough! I never noticed when I had my amiga, although it was a 1200 (I did have a 500+ but again never noticed) so I don't know if it was wired different or if I just never looked lol

+RefractionPCSX2 It's very subtle on the newer models but def. noticeable. I have an A1200 here, too. I think it's only the first gen A500s were it's completely turned off.

Must have been it! I could usually not tell if the light was on brightly or dimmed so it wouldn't have showed up :) But interesting quirk! Thanks for clarifying :) And great video of course! Got yourself a new Sub :)

I disagree Jan as the A500 was Great when launched to the market in 1987 so you repairing it have made it Great Again! LoL And keep doing the videos bud we love em !

Thanks! No question about the greatness of the Amiga. I was totally blown away by its capabilities when it came out! I was referring to the Donald Trump slogan I don't necessarily approve of. ;)

Who can resist? I bought one on a flea market for 2,50 euro. I dont have a need for more, but..... The machine has a common fault, the keyboard chip.

+mdftrasher That's a good price! :) Yeah, the IC on the keyboard PCB fails pretty frequently. There's also tantalum caps on some keyboards that can fail in naughty ways.
