Someone else beat me to it with the idea of simulating the simulator :-)

My approach is generally:

1) Fix the original if time permits
2) Simulate the original using what of the original is available - but
without making mods to the original equipment such that 1) is out of the
question at a later date.
3) Simulate the original on completely modern hardware (ala xmess etc.)

Note that I don't particularly like step 3 at all, and that there should
really be a step 0.5 which is "realise that I don't have enough time to
do any of it" :-)

Yep, I always places like that. I'm not sure why the parallel doesn't
happen for computer collections (I mean, sure, we get an awful lot of
broken donations, but even so)

Actually on that front it's not so bad as it was when you were there -
I've been having a good sort-out of the office, D Block etc. so it's
much easier to find what you want when needed than it was when I first
started going there! We've sort-of got an arrangement on travel expenses
now (after much arguing!) which is certainly a bonus.

Cambridge uni kindly threw a couple of rack-mount PC servers my way last
week with a whole pile of RAID storage, so I should at least have a
decent platform to keep disk / rom images, electronic documentation etc.
on now. I could do with rustling up a DLT drive from somewhere soonish
though for tape backup.

There's not much fixing of hardware going on at present, but then of the
exhibits in the museum room itself nearly everything's operational so
sorting out the stores and the like seemed a more sensible thing to do!

Components expenses I haven't figured out yet - but then I keep on
unearthing piles of components over in D Block so if I can get organised
over there we probably have replacement ICs and the like in a lot of
