Subject: Micropolis/Vector Disk

A friend is having problems with a Micropolis Disk System on a Vector
Graphic (S-100) system.  Does anyone have documentation for the
Micropolis DOS (MDOS) and/or source listings for the disk driver and
boot prom on the controller card (at F800-F8FF) and/or an MDOS disk
with the DIAG disk diagnostic program?

We only have CP/M disks for the thing, maybe an MDOS disk will boot where
a CP/M disk won't.  It seems to boot some sectors and then goes into a
loop of endlessly recalibrating and reseeking before the boot is complete.

Answers direct to me, please, as I am not on either of these mailing lists.
