Hi there. New on the forums.
I just got hold of a IBM PS/2 Model 30 (it has some kind of 386sx update, I think).
Of course it had the 161 and 163 error at bootup, because of no battery for BIOS.
I took the DS1287 chip out, and modded it to a 3V battery, like several guides show online.
The mod looked ok. But when I inserted it back, I accidently flipped it 180 degrees, and turned the PC on. Nothing came on screen at bootup, no beep. I discovered my error, and flipped it back. Booted up, and again blank screen, nothing. I waited a bit, and touched the DS1287 chip, and it got hot quickly. I quickly turned off the PC again, and tried 2 mins. later, with same issue. I tried disconnecting my new 3V battery mod, and tried again. Same issue. Nothing.
What concerns me is that the DS1287 kinda gets how within 30 sec. when booting.
Question:
1. Could I have fried the chip like this by flipping it 180 degrees making the pins align wrong on my first try? Did I do that? My 3V battery mod was installed when doing that first try.
2. Could I have accidentaly ruined the whole motherboard, making this PS2 unusable forever?
3. Should I just order a new DS1287 and try again?
4. Shouldn't the IBM boot even though there isn't a clock in there? That's why I´m thinking I may have fried the whole motherboard?
