Hello,
I have had my grandfather's IBM PCXT for quite a while now, but I've never gotten it to boot. It doesn't even post or spin up the hard drive normally. I have found out from this web page that the power supply will not provide power if it detects a short. So, to check this, I simply unplugged the power to the motherboard and so the power supply is only connected to the hard drive. In this case, the hard drive spins up. From this observation, I am pretty sure the issue is caused by a short somewhere on the board. (Also I have tried the board with no expansions on it at all) What I'm wondering is if there is any better way to try and find said short than removing each capacitor one by one and testing them? I'd rather not be taking that much stuff off the board for fear I won't re-solder it in right. If there is no better way, would there be any indications as to where I should start looking first? (IE where maybe this happens more often?) I'd really love to get this machine running, so thanks in advance for any help I can get!
