I think that you are Australian? I have never heard about the Sord M23
in France. This must have been one Japanese micros. This would explain
that you heard about it, since Australia is nearer from Japan than
Europe. I made a quick search: the problem is that there seems to have
been several "M23" models and I don't know, of course, which one was
running CP/M (the other versions seems to have run a proprietary
system). Maybe you could ask one New Zelander who published an advert
to sell one Sord M23 the 3 August 2008?

Well then, the Sord M23 is a rather rare machine, damn near as scarce
as my Microbee, but not quite, though it is more fun to play with in
my humble opinion.
Comes with:
Sord M23 ( of course ) in the box, very tidy though with some
yellowing, working very well. Has disk controller cart.
Sord colour monitor
Sord dual external floppy drives
a number of disks and manuals including Sord PIPS software.
It's a nice set up, it all works well and there are even some games
amongst the software.
Location: Dunedin, Otago

There are two ways to go about it. Find another SORD user, I think
some appeared her ein the USA.
The other is more intensive. You would need enough info about the
SORD to implement the BIOS portion of CP/M which is the machine
specific part. The rest of CP/M is portable to most any 8080/8085/z80
based (for CP/M86 any intel 8088-x86). You can then use any flavor of
existing CP/M for the components you need to assemble (port) to yours.
I assume the SORD has soem form of mass storage like floppy or hard
disk.

No idea what the CPU chip is. If it is a z80, 64180, z180 you can
use DOSPLUS 2.5, which is available on my page. Access:
<http://cbfalconer.home.att.net/download/cpm/>
If you don't know run DDTZ (also available there). It will tell
you what chip it found. Source for everything is there, except the
PascalP system, which got lost in a combination disk crashes, theft
of floppies, etc. The object code for Pascalp (pcode version) is
available.

Try the download section.
AFAIK, Sord M23 Mark II and Mark III are both Z80 based.
I am not sure the first version is also Z80 based, but why not ?
The Z80 was better not only "opcode-wise", also if you have to design a
new system, the needed additional 12volt for the 8080 was very annoying.
If an old Z80 based system has only (max) 64K RAM, I would also
recommend DOSPlus (or at least, QPM).

It works fine with the 64180 (or Z180) also.
Hi Chuck,
I'll definitely give DOSPlus a try once i have a way of formating the
floppy disks to SORD format.
Many Thanks.

Hi Peter,
I'm pretty sure the CPU in the machine is a Z80 (same as marl ii &
iii). Once i have a way of formatting disks i'll give DOSPlus a try.
Many Thanks,
Nik
Yes, I believe this. But that's a different question, because nowadays
how and where can you still buy a HD64180 or Zilog 180 ?
And that's not the original status of the machine, if he just enjoy to
see his old system running, "tuning" the Sord has no importance.

Peter
The difference between the various 'mk's of M23 was storage.
M23 mk I had dual 3.5" floppies
M23 mk III had dual 5.25" 100tpi 320k floppies
M23 mk 41 had dual 5.25" HD 1M floppies
M23 mk V had dual 8" floppies
M23 mk X had hard disk (5 or 10 MB)
All had a Z80 CPU, 128MB memory (except the cut down M23B which I
think was Japan only) and an option for an Am9511 coprocessor.
I'd also be keen to track down any other M23 (or M68) software! I own
two M23's, an M23EX and an M68.
The floppy format on the mk III is 320k 100tpi single sided, variously
called DD or QD - DD disks usually work fine. HD disks do not work,
and the format is physically imcompatible with any PC format.
