I put one of those in.
First and only SCO *UNIX* (as opposed to SCO Xenix) box I ever
installed.
But before we turned it into a server, we put DOS and Doom on it, very
briefly. The built in UPS could power a VGA monitor and we had a bit
of fun pushing each other along a corridor, one pushing the AVX/FT and
one a wheelie chair, while running Doom on a PC that wasn't connected
to mains power. The world's biggest "laptop".
That must have been quite a workout as I have heard they weighed almost as much as a
refrigerator. The built in UPS seemed to be a unique Apricot feature. Even after
Mitsubishi bought them out they kept including the built in UPS. Which makes total sense
for a standalone server back in the day before racks became common. I have looked for one
here in the US but haven't even seen a glimmer of the machines.
