For anything more sophisticated than your coffee pot the RP2040 from
Raspberry Pie is a fantastic little chip, dual core 133 MHz Cortex M0+
with 8 PIO engines, 264K of RAM, ADC, UART, SPI, I2C all for under a
dollar. I designed a fully functional RP2040 with 16 Mb flash for under
$2.00. In large enough quantities that's encroaching on 8 bit PIC
territory at over 1000 times the memory and CPU power.

Who still uses the Z80 line for new projects?
Wouldn’t it be easier
and cheaper to just use an Arduino or Raspberry Pi?
I dissected a dead coffee maker last week that has a current-design
8051 clone running the control board.
Well-known instruction sets and "Nobody cares if I clone this" make
powerful arguments
