I have what i learned is an IBM clone of a 5160 turbo XT. I am having nothing but problems restoring the motherboard and would like to get a replacement on ebay as i am impatient and this PC has a goal to serve. I am not competent enough to identify what i have to find a replacement. i have included a pict below. So what is this motherboard? on ebay i find many original and clone 8088 XT boards with 640kb. Is that what i should be looking for? Or better yet does someone on this forum have a working replacement to sell me please?. I would also give away my clone board for free, Thank you very much.
