Zilog Z80 bites the dust

dougw

I just noticed this extinction event.

Littelfuse who own the Zilog Z80 IP announced the Z80 would cease production in June 2024.  (Semiconductor fab lines are not interested in running a 4 micron process)

Fortunately the eZ80 system-on-a-chip is still in production if you want to pursue this technology.

At one time I was ultra keen to obtain or build a Z80 microcomputer, but never managed to scrounge enough money until recently when I made a low cost emulator on an ESP32....

    A z80 system was the first one I built back in the late 70s (wire wrapped a board! with S100 bus connector! Had a working (well 40 minute maximum uptime) S-100 bus system!). So it's kind of sad, but like most old things, they pass away into the past (but at least I got me a PiDP-10 to recreate some other 70s memories :-).

    Anyway, for those looking to recreate some CP/M memories, this may be the last chance to grab a RC2014, IMSAI replica, or equivalent kit at least before they're redesigned for more available chips. Or build your own from scratch while they're still in stock at distributors.

       S-100 system, yup with a TDL Cpu and the IMSI Front Panel, had a whopping 64M in it. and I had a 100 amp Interdata power supply running the dam thing. but here is the best part I had a KSR35 with a tape reader/punch.. No cassette, plus 4 drives, (disks) It got retired when I picked up a single board
