I got a crazy and crazy cheap set of an Amiga 2000 and 500 with an insane amount of accessories and software. The 500 has a faulty PSU that I'll put way to the side for the moment.
The 2000 worked okay until I tried to swap out the HD. Then it progressively had trouble booting until it would just either freeze at a black screen or freeze at certain points booting from the Workbench 2.0 Install disk (when it asks you if you want to do a keymap or something).
I reseated all the chips but I accidentally damaged Fat Lady. I used a knife; I've used knives every time I've done this but this thing was wedged in there and I didn't realize what I was doing until it was way way too late. So there are two issues. 1) I pulled a pin out of Fat Lady [*a second one fell out...]. I can't figure out how to solder it back on (there's nothing protruding, really); put that to the side for a minute. 2) I did some damage to the socket itself - mostly broke bits of the plastic dividers off and pushed the metal pins toward the sides (i.e. contact issues, maybe).
I've spent a fair amount of time pulling the metal pins forward and I've replaced Fat Lady (minus a pin) with Fat Agnus from the 500, which I believe should be compatible - they are both 8370s and I have not found any notations to differences - but feel free to jump in.
Now I get a green screen. I had washed the board so I'm going to give it a few days - or at least until tomorrow - before I try again. I have some issues here, though. 1) I need a new Fat Lady and they seem to be a little hard to find, and I'm cheap. 2) Regardless, what are my options on the socket pins? 3) I don't have a good picture of where those pins are going - do they just descend and sit (but are not soldered) to contacts on the board - i.e. can I just pull them (not break them per se) out or is that also disconnecting them... 4) And then can I insert little pins or something or is that insane?
This was such a good afternoon that turned into such a total disaster. On the other hand I can also just sell the machines and try to get a very barebones 2000. [I have a VGA card, SCSI card with 8mb of RAM, VR Glove, extra floppy drive - internal/external. I've been waiting almost 20 years to try an Amiga... sadly short-lived.]
After reading this, [http://www.amiga.org/forums/showthread.php?t=68417&highlight=Green+Screen] let me note that my machine turns on and flickers between green and like interlaced gray lines 10 times, then gets stuck on green. So it's not hitting a reset sequence - unless/and idk what the 10x screen switch stuff is. But this is clearly not purely a display issue. It doesn't get near kickstart/the boot cycle.
