Hi Dave There is quite a bit of stuff on line. If it uses the
360 drive ( rated at 320 forthe M20 ). We can transfer a lot of software to it from
archives.We have many manuals, some in Italian but most have English versions.We have a
schamatic that is mostly correct.Do a search and you see it all.Dwight
The olivetti M20 has a CPM for it. I'm told
it was based on the 68K
CPM that was mostly C code.
If any one is interested, there is an M20 on ebay. Too bad it is missing the
monitor. It was said to use different scan rates and is difficult to find a
replacement. I'm told that the M24 monitor can be made to work.
One can also use the boot sequence to us an external RS232.
I wonder what memory confiuration it has. Most were 224K but
it can use up to 512K.
There is a PASCAL for it as well but that takes +300K to run.
Anyway it is a cool Z8000 machine. I'd love to see someone in
our group get it.
I'll see if I can grab it. I've done a bunch with Z8000s (both chips
and systems built around them) and I like them. I'll see if I can bring
it back to life somehow.
