Which reminds me, does anybody else remember those
machines that had
multiple CPUs in them? Or the option of plugging different ones in?
Seems to me real early on there were some mfrs trying to find as much
compatibility as they could with pursuing options like that. I remember
one Taiwanese-made clone of an Apple II that had a Z80 on the main board,
and of course the c128 has that similar setup (though the way the hardware
was structured the z80 effectively ran at something like 2.5MHz). I
remember some other system where you could literally plug in different
processors for different uses, but the brand name isn't coming to mind at
the moment.
Extremely common in the S-100 world (think Godbout/Compupro,
Cromemco, etc.). Bill Godbout may have offered the widest range of
processor boards from a single manufacturer. Early on, there were
6502 S-100 boards, but not very popular.
There were other non S-100 vendors of optional CPU configurations.
Didn't The Digital Group offer a choice in their boxes?
Cheers,
