Subject: Help with lost CP/M boot disks
Date: Fri, 15 Nov 2013 06:51:12 -0200
Firstly, I don't remember if I had already posted it here. If already,
shame on me :o)
I have a brazilian machine called Itautec i7000 (not the i7000PCxt).
This is a CP/M machine which uses a ROM cartridge and disks. I was able to
get its disk interface (and extract the BIOS) but what is said, is that this
machine uses a specially tailored version of CP/M called SIM/M. It uses the
NSC800 processor and has 64K of RAM. Can anyone help to find a disk that
boots this machine? Or direct me in how can I educate myself about what is
needed? I know nothing about CPM, and this is a pretty rare brazilian
computer (even here in Brazil), so it would be great if I could at least
boot this beast

Thanks

As I recall the NSC800 was a Z80 on the inside but a 8085
on the outside.
I would guess that all but the low level disk could be regular CP/M
or Z80 improved CP/M. There are several books on CP/M that
will help you figure how to build a boot disc. I don't recall the
name of the book I used to build a boot disk, years ago.
