Amiga 600 recap woes
« on: August 10, 2020, 08:27:00 PM »
Hi all, just need some guidance here to see if anyone can help point out whats needed, so i can see if it's within my capabilities or more likely... not...  ;D

So, A600 recap'd. Liquid polymer caps. infinite life etc. woohoo!
Corrosion spotted around the audio area and cleaned up. yay!
IDE port replaced as old one had broken pins - big big plus. machine not useable without bootable large media.
Boots up off floppy like a champ!
All awesome so far, except.
can't detect anything off the IDE port. not so good
PCMCIA detects something on insertion/removal - but "card corrupt" also not good.
one of the audio channels is just low volume digital noises.

putting an accelerator on the CPU (ACA630 or Vampire2) suddenly we can kinda of detect drives, and read drive definitions - with added character corruption. can't write anything back like save the RDB or partitions without crashing.
Also with accelerator, able to ... kinda read pcmcia cards. it's like half the name is missing or similar to IDE definition character corruption. like Netgear becomes NeTge, n0T0e0r
I'm guessing the accelerators do some buffering of some kind that the plain ol' 68k just doesn't have - which means we can get some data out of the noise?

i've tested all the pins on the IDE, and everything buzzes out correctly. have i got a cap not making a good connection somewhere or is something more going on?

i dunno. i suspect it needs a more insightful mind than mine, and better tools, to figure this out.
Thanks for your time  8)

haha, fair enough, i guess it was a bit much to ask without some hands on time with the board :)

so, who can we recommend can help poke it with a soldering iron? I really would like to get her rolling again.

many thanks for your time

Can you test with DiagROM?
