I wrote a system for VETS on this system under Mirage. A also wrote a virtual terminal system which allowed multiple sessions on each terminal (Much like ALT+Fn keys in linux). It worked well, but operating system support was a bit of a problem sometimes. I also wrote SCSI drivers for Mirage to allow for an external SCSI drive.

I worked at T.D.I in Bristol in the early 80''s and ported the UCSD p-system to this machine. It was my favorite machine at the time, beautiful spec, construction, but sadly we never made a multi-user version. The graphics chip was great fun to program for (did the Turtle Graphics for UCSD as well). Always sad that this one wasn''t a success ...
(but it couldn''t compete with the Stride/Pinnacle machines)

I remember the Mirage OS slightly. It had a very VAX/VMS-like user interface, not sure about the internals - and was used quite a bit for soft-realtime in process control industries in the UK.

It also appeared on a number of other 68k-based machines.
