I'll do you a swap... I have seven of the plastic-cased ones ;-)
I would like to get one of the metal ones sometime just to complete the
collection a little. I've never even seen one to be honest, just the
plastic variety. Even Bletchley don't have one, just a mammoth pile of
380Z's.

I'm not sure what this one has yet. It came with a mono monitor, but a
quick glance the other day shows some circuitry behind the BNC
connectors for the colour output too - but maybe they all had that
anyway. I'm going to have a closer look at it in a moment.

Nope. The COS Reference Manual says that a listing is available on
request, as you say. However, the 380Z Information File says that "A
complete specification of the Research Machines resident monitor program
used with the current disc systems is given in Research Machines'
Firmware Reference Manual"
That latter document might be useful and is on Paul's site -
http://vt100.net/rm/docs/pn10971.pdf
However, a) it's a web document, b) it's in PDF format and c) it's 30MB
so I'm not sure what your chances are of being able to get it and read
it! It's 190 pages or I'd print it out and post a copy if it looked like
it contained relevant stuff.
I just downloaded it but PDF rendering is slow as hell on this computer
so I'll look at it on a different machine tomorrow.
cheers
