Two interesting pages about the Olivetti M20 – one of the few computer which have a Z8000 and can run CP/M-8000

Full with additional links and infos, more than just a vintage computer museum entry:

To get an impression from what I’m talking – here’s an image from an M20 machine,
running CP/M-8000:

The machine was selled in 1982 with PCOS (that’s an operating system with cryptic commands, even more cryptic than CP/M was)…
There was an additonal 8086 card available to run MS-DOS, but that’s another story.
The cpu was – to document it more accurately – a Zilog 8001, the cpu family is named ‚Z8000‘.
Still one of the most „rich“ web pages about the Olivetti M20 can be found at

  1. I’m interested in CP/M 8000. I checked the Web links in your blog entry, I did not see any of them mention CP/M 8000. The M20 was sold with a custom OS from Olivetti. What’s the details on the M20 you show with a CP/M 8000 display message?

  2. To be able to run CP/M-8000, you didn’t need anything else than a M20 machine.
    Look at:
    http://www.cpm.z80.de/source.html (search for ‚8000‘ on the page)
    http://www.cpm.z80.de/binary.html (search again for ‚8000‘ on the page)
    There is the source and the binary for it.
    If you just like to get both (bin and src) immediately, try to download
    http://www.cpm.z80.de/download/cpm8k11.zip
    If you look just for a manual, take that:
