Hi there, I would like to kindly ask for some help regarding identification of this 486 board so I could get some kind of manual. There is no serial, no code nor revision on it printed anywhere. There's only a sticker on the lowest ISA slot that says Gericom and a number 93617467 which does not lead me anywhere. This is my first attempt to recreate a 486 and I need to make sure I do not miss anything. This board came with this particular CPU so it should be set correctly, but who knows. I don't want to blow up anything. There are also bits and pieces of help (switch positions) printed on it but not all is covered.
So far I have managed to remove its old leaked battery, clean the corrosion with white vinegar and IPA, then solder on a new barrel battery I just purchased. I would later later like to replace the existing CPU DX40 with an DX266. I'm still afraid to try to run the board since I have no idea if that PSU I have for it is healthy (I'm not very good with multimeter) 😀 Thanks in advance.
