Okay, I've got the schematics for the Explorer 88/PC (Netronics R&D, New
LItchfield, Conn), which uses an 8250 for async, has a separate keyboard
and cassette interface. No video as far as I can tell.
I also have an ISA card with 6 banks of 4164s and an Intual DUART on it.
And I recall the "Blue Seed" kits.
Lots of interest in the early PC, apparently.
