I am having a problem with one of the disk drives in my KAYPRO II.
The alignment definitely seems to have slipped. I can format and
read a new disk but cannot read old ones. I have decided to try
to adjust the radial alignment. I have access to a DYSAN alignment
disk, PAT-1 tester, and scope. My problem is lack of documentation
on my disk drive. Can anyone tell me which test point provide
the index signal and the outputs of the read differential amplifier?
