Well i seem to of found the issue with writing to disks with my DISK II drive. The Transistor in the CA3146E chip that drives the Q2 right/Write Transistor is shot. all the others on the chip test ok, but pin 8 is dead..
Seems like this is now a discontinued part. I have 3 Ebay ones coming from China, with an ETA of Oct/Nov. Anyone have a better source? Digikey/newark/etc all fail to find it.. I am not interested in paying as much shipping as the cost of a DISK II drive to get it here (Canada)..
