Was that Motorola? I thought it was Mostek or something like that. I
remember they did the 6500 series (6502 processor, 6522 versatile
interface adapter, 6551 (I think) programmable uart, etc.). Motorola did
the 6800 series. I used the MC6802, which was a 6800 with internal clock
(just add a crystal) an 128 bytes of RAM. I think they had some designers
in common. I think I recall the 6800 was first, then some people went off
to do the 6502. The big difference I remember was the 6502 had two index
registers, while the 6800 had just one. I think the 6502 had 8 bit index
registers, while the 6800 had a 16 bit index register. I think the 6800
had two accumulators and the 6502 had just one. The 6502 was used in the
Apple II, the VIC 20, Commodore 64, etc.
