I remember the Research Machines 380Z and wouldn't mind getting one should
the opportunity arise. But I have no recollection of a "Special Control
Unit", so does anyone know what this is?

Some kind of peripheral maybe?

The PCBs and backplane in the last photo are not standard 380Z boards. The 380Z
doesn't use edge connectors like that, the boards just slot in guides and are joined
by a 50 way IDC cable (which also carries power (!)).
To me this looks like an RML case that somebody has put an S100 backplane and
a few boards in. I don't think it's an RML product (but would love to be proved
wrong).

That's interesting... the case is typical of an early machine (later,
black-cased systems were a bit more rugged), but I'm not aware of any 380Z
system using a solid PCB backplane - they all had ribbon cable for the
system bus.

As Jules and Tony have said, that's not 380Z internals so if that puts you
off I'll have a punt just for the power supply ;)

Be my guest, I am only interested in a 380Z really, and would prefer the
black enclosure I remember using anyway.

Very true. I've just looked at my 380Z and the PSU does look different.
However, unless bidding goes nuts it's worth it just to see what it actually
IS, and since it's Watford I can pick it up.

... Which also may well not be RML original. The 380Z has a regulated PSU,
S100 has separate regulators on each board and an unregulated PSU.

If you do collect it then let me know what you discover.
