IBM PS/2 Model 50Z


 

This one was in the same car as the PS/2 model 30 but I didn't actually get it until about a week later. I was not so fortunate with this one as it will not go at the moment . It gives an error on start up indicating a voltage supply error to the disk drives. The unfortunate thing about these old PS/2's is that parts are not so interchangeable as they are on newer computers, so it is not easy to swap parts about to diagnose the problem. The PS/2's that I have got at the moment all have differences, even so I haven't given up hope of getting it going again.
