Disk II
Posted by: bibilit on 2018-04-22 02:03:06
I am trying to repair two Disk II.

probably both have the same issue, so swapping cards or parts won't change the behavior.

The best of the two units will spin but won't read, from what i have gathered online, a faulty 74LS125 can be the cause of the problem...

The second unit will spin also, but the driving belt has a tendency to slip from the spinning drive ?
