Needing some help. I have a dead Tandy 2100 Model 10 and have been trying for some time to revive it. I purchased new power supply thinking that was the issue but it is not. When I plug P9 into the motherboard, the fan on the PS spins and the motherboard will beep, but when I plug the P8 either alone or with the P9 it does absolutely nothing. I have removed all cards and memory but to no avail. I removed the MB and visually I can not see any dark spots or rust, so I am asking to see if anyone here has a place I should start looking as far as voltage points or impedance tests I should perform. Thank you in advance to anyone with suggestions.
