Subject: Minimum configuration?

I just got given an issue 7 board, from which virtually ALL the components
have been stripped.

Has anyone any idea what the ABSOLUTE minimum chip set needed to get a running
system?

Obviosly I need a 6502, and I think I need a 6845 to do the memory refresh
(they left the RAM in, as its all soldered).

I can obviously live without the model B stuff, but do I need all of the 
model A chipset? Can I live without a Video ULA (If I don't want video -
though I probably do), a system 6522?(I don't want sound, and probably don't
want a keyboard - I'll install a serial ULA, and use my current machine as
a keyboard).

I do remember that they don't power up without a keyboard, but figured that
that was simply because the break key was on there (or some other simple fix).

The problem realy has wto parts to it, as I;m sure that most of the hardware
I'll be dependant on will only be required if I run the MOS - how much more
culd I get away with if I ditched that too (or patched it?).

I've a few ideas for things I could do with it - A second display would be
nice. Failing that I could use it for a Teletext server.

It's pretty unfortunate that both the Video and Serial ULA's are missing
as these will be hardest to get hold of. Anyone like to comment on my chances
of getting this thing going? (Anyone got a pile of spare parts they're willing
to part with?).
