All these ISA boards everyone has -- are they 16 or 8 bit?  Doing the little
8-bit bus would be simpler.

I had this idea of doing a simple 16-bit 3051 I/O bus, with a daughterboard
that converted to ISA for those who want it.  The ISA cards would plug in
sideways.  Several computers do such a thing.  Getting a box with sideways
cutouts would then be the hard task!

Well, then you'll need to put IDE on the motherboard.

Yup, there goes the standard PC case, so anyone who wants to use their PC
components has to pay another $100 for a non-PC case.  This just sounds
outright dumb.  And knowing how reluctant some ISA cards have been to seat
themselves properly, I see lots of breakage on the edge connector between
the motherboard and the ISA card.  Lots and lots of breakage.
