C256 Foenix Project – What could have succeeded the C128?

I assume you mean the 6801/68xx family which is entirely different than the 16/32 bit 68000

>the reason the C-128 had CPM was they were afraid the Z80 would make a comeback.

Not really, I am the one that made the decision to build the Z80 into the C128 and it was due to multiple problems that could be solved by putting it on board. Namely the CPM cartridge would have meant that I had to build in over an Amp of excess capability into the power supply ("switcher" instead of "get warmer") and the cartridge that had problems on the C64 had even worse problems ion the C128.  It also meant we had apps to use the 80 coulumn on day one.

>The fact that the C-16 and other computers were given less memory meant that Commodore was going backwards instead of forwards.

That was a weird computer that was completed before we even knew about it as it was done in Tokyo. I think they were trying to use up TED chips to get their investment back out of it and the 16Kx4 DRAMs (64K total) made the 16K machine possible (Didn't exist in '82/'83)

"... the MOS Technology 6502

"... the MOS Technology 6502 was based on the Motorola 6800 CPU (released the same year as the 8080, and both chips initially sold for $360). In fact, many of the engineers behind the 6502 had worked on the 6800 at Motorola."


" (MOS Technology also made a 6501 CPU that could be used to replace the 6800 on a logic board, but Motorola filed suit against the upstart company, which agreed to withdraw the 6501 and pay Motorola $200,000.)"-IBID

It is mistake for adding an extra digit and confusing the two.
