Those are similar tot he round mouse (Hawley) that
were used for the early
VAXstations. Those were not PC compatable. I've never seen
a mouse on a z80 system (most didn't ahve graphics).
At a local electronics trade school where I worked (as a programmer and
teaching digital briefly), we had a bunch of Televideo TS-803 Z-80 based
CP/M workstations; each had a mouse port, we bought only one mouse tho;
it was an early Mouse Systems unit, optical, but requiring the dedicated
optical mouse pad. Worked quite nicely, tho, and I wrote a rudimentary
drawing program for it to create graphic objects for the computer-based
simluation of our digital trainer/breadboard systems.
Graphics capability was 640 x 280, kinda thin vertically, but the ROMs
had line types, fill types, etc.
