386 PC (Suntac-12 mainboard)

Released ~1991: My 386 PC seems like a very “general” assembled PC put together with different manufactures parts. Suntac-12 motherboard fitted into a casing labeled “Mega Silent”, and it actually is very silent . I found this PC in the electrical waste dumpster at my job. It was opened with the HDD removed and keyboard missing. I took it home and found the CMOS battery had leaked onto the main board and possibly made some trace damages.

Battery leak: I cleaned it up and measured only the one trace to the battery + and one trace to an port for external battery + was damaged. Fixed those with soldering in wires and had a new 3.6V chargeable barrel battery laying around which I connected to the ext. battery port in order to locate the battery away from the main board, so it would not leak and make a new damage (during the next 20 years or so). Now the computer remembers BIOS settings and date/time.

Missing keyboard: Soldered up an adapter for making a PS2 connector keyboard fit as well as I didn’t got any loose DIN-5 connector keyboard laying around.

Hard drive replacement: Had an IDE (PATA) – CF card adapter laying around and prepared a 4 GB CF memory card as HDD, setup as 504 MB (maximum size to be supported for PC’s at that time).
