It's still active as a mask for a more complex system on a single die. Even the support chips are available. The Juno project, orbiting Jupiter, had a Z80 compatible core for the radar signal processing.
replyThe cpu possibly, but I had a hard time trying to find the support chips (ctc, sio/pio, etc)...
replyMany applications didn't even use those peripherals so I suppose production ended earlier.
replyThe Z80 could even refresh the RAM by itself. It was not like the 8080 which required two support chips only to function.
Do you have an actual use for them? I might have a few tubes of Z80-CTC & SIO in the basement if I haven't given them all away yet.
