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.
