PM8500 no signs of life
They come in about a million different variants. The DIP switches are not necessarily standard between them, so if you lost the manual, you'll be guessing. Post a picture and see if someone has a similar one.
Try reseating the processor card. If it's even a little up in the slot then the machine won't work.
Waiting now to get new processor card and some Vram to test the system further. Sadly tho my darn power switch has broke in two places. So need to find a new plastic case button or i wont be able to have the lid on the system
I'd try a unsharpened pencil. Any button you get will be brittle.
