I was working from scratch, and was finding debugging to be exceedingly
difficult. These days it would be somewhat easier as I have a good
logic analyzer I could hook up to the MC68010. (An in-circuit emulator
would be even better.)

Yes, and there is enough clearance (barely) to fit such a thing in,
though the MC68010 might have to be soldered in place as their might not
be enough clearance for socketed components on the daughterboard.
