Question about Timex (TOS) CP/M 2.2
Bruno Florindo
disks and found out that one of them, with the title of 'Timex
Portugal CP/M 2.2' had been formatted and there was nothing that could
be recovered. I guess that at the time the user didn't think of how
important it would be now... This has made me want to find that
version of CP/M even more, but none of my fellow Portuguese friends
know anything about it. Can anyone shed some light on the subject or
give me a few suggestions on how to find this again? Thanks in advance.

All versions of CP/M 2.2 are identical, except for the load point.
Any system with a LOADCPM has a relocatable version. The only
differences are in the bios. See the CP/M documentation for its
requirements.

"identical"??? The command processor may be but don't forget that
some of the utilities may be customized! Example: Kaypro's program
for formatting disks was all menu driven and had customizations specific to
Kaypro hardware. Likewise Commodore's CP/M 3.0 FORMAT won't work on
other hardware.

I had the same problem and Yarek helped me, now I can help you :-)

Use CPCDiskXP to write to 3" diskette (and remember to set drive jumper
to "B").

I managed to read both disks using the technique I described in
<imo9hg...@seasip.demon.co.uk>, though the second one needed a different
entry in diskdefs (only two system tracks, and a different skew):

sectrk 16
blocksize 1024
maxdir 128

@John: Wow!!! Thank you so much!!! I'm going to share these news with
everyone who was helping me, and I'll credit you, of course. I know
it's just the beginning, but I really, really appreciate this!
@Zbigniew Niedzwiedz: Thanks! But is that the original TMX Portugal's
CP/M 2.22? Or is it Jarek's modified/expanded version?

I will include that entry in the diskdefs, but do you have any further
information on the system that uses that format? A SKEW OF 5??? That
is awful for a system as modern as 3", because it forbids faster disc
functions allowing a smaller physical skew.

genuine 2.2 version. I think the text display is Jarek's own. I may be
completely wrong. However, it should be 100% compatible with the Timex
version if it is differnt. I'd send Jarek an email and ask him. Tell
him I said hi!

One of them (terminal) is in TOS A.2 format, second one is in CP/M SSDD
(described above) format.
For TOS A.2 maybe format definitions from 22disk will be helpful:

On my diskette is:
Side A:
*** MONITOR EMULATOR for the TIMEX COMPUTER **
Version P1.1
* Copyright by TMX PORTUGAL *
( P/N 398-909465 )
Side B:
CP/M Version 2.2
Copyright by DIGITAL RESEARCH,INC.
Cbios Version A1.1 Copyright by TMX PORTUGAL
SERIAL NUMBER 5005-62028
You can delete KSIAZKI.* from side B - obviously it's not a part of
original CP/M system (means "books.*" in polish).

These things are way over my head. :)
So, is that disk available for download as .DSK? Is it the same you
mentioned two days ago? I would like to be able to use cpdwrite to put
back the original software on my 3" Timex cp/m disc.
@Michael: I'm not sure what the diskdefs. Do you need the complete
details of the Timex TOS too? John helped me figure out how to get
data from my disk images here:
Can Amstrad PCWs read Timex TOS disks?

The other format has a skew of 7:
diskdef fdd3000
seclen 256
tracks 40
sectrk 16
blocksize 1024
maxdir 128
boottrk 4
os 2.2
skew 7
end
The documentation referred to on the other thread in csa8 is:
<http://timex.comboios.info/tos.html>
where it describes several variants of the Timex format. The extension for
user area labels (first byte of dir entry = 0xFF) is one I haven't seen
before.

To handle other than standard TIMEX CP/M disk I had to set 2 things: DPB
and interleave (skew). In TOS (every version) it was 7, in CP/M 5.

Well, you may have an easier solution now.
Download TIMEX2P3 from <http://www.seasip.info/ZX/unix.html>. It ought to
convert .DSK files similar to the ones I've seen to a format that can be
read on a (real or emulated) Spectrum +3, or to 713k PCDOS format.
I've included a compiled version for PCDOS, and source for Unixy systems.
zxbruno
Justed wanted to thank you for the utility you created. It worked on
all my .DSK files.
caeta...@gmail.com
Can some one give me a working link for the "cpmtimex.zip" file or other .DSK images of the original 3" Timex floppy?
The "http://8bit.computer.lublin.pl/files/cpmtimex.zip" URL is not working.
Thanks,
José Silva
Zbigniew Niedzwiedz
should be OK.
