I've got my monitor ROM for the Quay 900 (MPS-90F) running well enough that
I can download programs into its RAM from the serial port, so I can start
debugging the floppy controller routines in the CP/M BIOS I'm writing for
it.
Quay reportedly provided a monitor ROM with the MPS-90F board, but my 900
came with a ROM that doesn't do anything but try to boot a double-density
floppy, and I don't have any boot disk for it.
I'm trying to get CP/M 2.2 running with standard single-density format
first, since that's suitabe for interchange.
