IBM XT class 5160 computer motherboard
I have an IBM “XT” I believe, it’s model 5160 with a motherboard that is not working, will not boot at all. It is a 640 K motherboard fully populated with RAM, but has two bios chips only. My question here is, who in the group would be willing to help me work on it at the workshop? I can bring a power supply and the motherboard, video card and probably a speaker for diagnostics, but not the entire computer since the board is already been removed. I should have a working eight bit video card to diagnose with. I have no idea where to start exactly besides the power supply, which checks out fine. Please let me know who is capable of helping, and if he/she will be at the March workshop this month. Mike Sent from: My extremely complicated, hand held electronic device.
