Hi,
I just got a new to me IBM Model 25, and it shows nothing at boot, no beeps, nothing. Power supply is outputting the correct voltage.
I pulled it completely apart today and found one of the 10uf 16v tantalums with no top. There are 7 total of these, and three 22uf 25v ones. They all have 3 legs.
Does anyone have a schematic or parts list for the model 25, or can someone 100% sure tell me if the polarity is (- + -) or (+ - +) ?
I'm just going to replace them all since at least one other is shorted.
Thanks!
