No one ever doubted it could be done -- physical access to the system unit
gives opportunities to crack root that the best modem connection can't
offer. That's why serious business systems are kept in physically secure
areas. To enter the machine room where I work I have to exchange the
card-key that gives me access to the building for one that gives me access
to that room -- and I have to trade back if I want to go outside to smoke
a cigarette.

Look in the /dev directory and see what devices are listed containing
strings such mt, rmt etc. Hell, mail me a 'ls -l' of /dev and I can
probably tell you -- some vendor device drivers gave things funny names.

Computone is best known for multi-port serial boards. These are probably
8-port boards to connect to terminals. What do the connectors on these
boards look like?

Yes, 'SPA' probably stands for 'serial port adapter'.

Is the mechanism a full-size Quarter-inch drive or one of those little
Irwin/CMS type drives?

Don't try putting a Soundblaster compatible sound card in that box
without careful setting of jumpers. Then again, Xenix of that era
probably won't support it anyway.

All of that looks pretty normal.

So what utilities are on the machine? Does it have the Software
Development package? (type 'cc' to check). Does it have the Text
Processing package?
