> Commodore had the largest warehouse of these in North America by 1984

That sounds like a story, have any more details?

sys_64738 is referring to Commodore running a tradein program for $100 off a C64 with any computer or videogame console. People purchased the Timex Sinclair for $45 solely to trade in (https://dfarq.homeip.net/wp-content/uploads/2020/08/timex-co... supposedly, Commodore used them as doorstops.

The C128 from 1985 had a Z80 built into it. Where did those come from I wonder?

Bil Herd claims he took the Z80 used in the prototype C128 from one of the ZX81 doorstops.

Great point. I just had a look in my C128 and they are just regular branded Zilog Z80s. I sure there's a story there too...

Thanks! I had no idea.
