Interesting - that's basically what happened with the two Atoms I was working
on, except that they came with a System 3 rather than a 4 (also missing the
Econet board, sadly).
The System 3 cleaned up nicely and after replacing around 40% of the ICs due
to corrosion (seriously) and fixing umpteen dry joints on the keyboard it was
back in good health again - unfortunately I never got the time to work on the
Atoms, other than giving them a good spring clean.
Sure - although a lot of Atoms out there don't seem to have the expansion
connector fitted (IIRC there are typically a couple of ICs that they need
too). The Atom Disc Pack (as you probably know) was just a drive and a
System-era FDC in a single case, plugged into the Atom's expansion port).
I merely meant that it was the first time I'd actually come across anyone
who'd used a System board (other than a Disc Pack) with the Atom; it doesn't
seem like it was a popular thing for people to do at the time.

No, most of my Atoms, including this one, came from Reading University. I
also got the System 4 that was used as the Econet file server. Ooh - you
don't see many Atoms using the expansion bus for System cards (with
the exception of the Disc Pack).
I think one of my other Atoms has one of the lab
I/O cards mounted
inside, connected to the system bus. the bench just
before I left for the US; both with lab interface boards
mounted in the bottom of the case. It's the first time I'd seen that actually
done, although I believe that somewhere Acorn do mention as a feature the
possibility of stuffing a System board in there...
The bus pinout is identical, all you need is a length of ribbon cable
with the right connectors on the end.
