I took more pictures of the unit after removing the chassis. They can be

The cpu main board is definitely the large L-shaped one that Roy Tellason
mentioned. Just eyeballing it, but what kind of backplane connectors are
those? They look larger than ISA connectors and appear to be 86 pin.
It seems to be quite clean inside and out. Not that I've had much time for
classic computers lately, but this one may be interesting for a while :)
