The disks are 'CP4 CPU Microcode' disks for a Wang Laboratories' VS-90
minicomputer system. Their only purpose is to load microcode or
diagnostic routines into the control memory on the CPU board.
Otherwise,the drive is almost certainly not a problem,
and you can
probably use an "industry standard" drive, such as a TM100-2.
But you will need a controller that can handle hard sectored diskettes.
Depending on the specs of the format (which you haven't tod us), it MIGHT
be readable with Northstar hardware, or it MIGHT be readable with Vector
Graphic hardware, etc.
I don't have, and cannot obtain, the specs of the format. What I do have
is a disassembly of the Z80 code from the EPROM. From what I have read
scanning old newsgroup postings, etc. today, I might be out of luck.
There's a dealer of old Wang equipment in Ohio that has one of these,
but they want a small fortune for it. I may have to abandon the idea of
reading these disks until I can locate hardware from somewhere else, or
the Wang dealer finally decides it's not worth keeping and scraps it
out.
