Who still uses the Z80 line for new projects? Wouldn’t it be easier and cheaper

I dissected a dead coffee maker last week that has a current-design 8051
clone running the control board.

True, but the Z80 is 5 volt logic. St
Good point but i’m not an trained EE, just a hobbyist so i’m just curious. I
buy Z80’s and other’s for repair projects but …

One more reason to use the 8080 subset when writing CP/M programs.
Aren't there already some licensed second sources?
Harris also made an all-CMOS plug-compatible Z-80.
