Hey guys,
my A3000 stopped working one day. Now, the reason probably is battery leaking. Funny thing is that I removed the battery a long time ago, and I'm sure I cleaned the spill. I guess in the end if wasn't sufficient, because I found corrosion damage that was more extensive when I opened it up afterwards.
Anyhow, so now it turns on and I get a green screen and after a few seconds it seems to "rebooot" and the same thing repeats. The custom chips that I could plug into an A500 seem to be ok (this includes Paula, Denise and Mrs. Agnus). I also tried piggy-backing good DRAM over the low 1MB of CHIP RAM, and no changes
Now what seemed interesting as I was mearusing voltages and checking out the motherboard is that the following chips get quite warm, tending towards hot (within 1-3minutes). I can still touch'em without pain or scorching my fingers, but they feel hotter than normal:
U252, U202 (what are they? PALs?)
U714, U701 (what are they? PALs?)
U253, U255, U257 and the ones parallel to these (what are they?)
The whole other side of the motherboard (where the CPU, kickstars etc are located) seem much cooler.
Can anyone with an A3000 verify how the chips should behave?
Much appreciated, as I don't have another A3000 and I don't know where else to start...
PS. Keyboard is completely dead. Ctrl-Amiga-Amiga does nothing, and the LED on the CapsLock doesn't light at all when pressed.
