Dimension 68000 was deliberately a multi-processor machine: 68000, 8088,
6502, Z80?

and, of course, we hafta mention Dec Rainbow and Eagle machines with 8088
and Z80

Basis? (Apple ][ copy) had Z80 +6502
at one point, somebody at Apple estimated that 20% of all Apple]['s had
Z80 softcards

There were alternate processor cards for PC, including Z80, 6502, 68000,
80386, . . .
