I think I saw a picture of it once (8bs?). A header
board with at least an extra socket for a plain 6502
to switch between that and the 65C12 (and, no doubt,
to make all the extra Master hardware invisible and/or
relocate it as appropriate in the memory map.
Recreating that could have practical uses even now. ;-)
