SVI-707 problems

You may well be right. I am using MSX-DOS boot image for SVI-728/SVI-707 and I believe it is MSX-DOS 1.

But in any case, I would like to use CP/M, not MSX-DOS...

This is what I do, I am not sure if it is right or not:

echo hello > /tmp/hello.txt
openmsx -machine Spectravideo_SVI-728

[PRESS F10]

set power off
diskmanipulator create /tmp/image.dsk 360
virtual_drive /tmp/image.dsk
diskmanipulator import virtual_drive /tmp/hello.txt

[PRESS F10]
Close OpenMSX emulator

To boot MSX-DOS:

openmsx -machine Spectravideo_SVI-728 -ext Spectravideo_SVI-707 -diska MSXDOS17.DMK

[PRESS F10]

diska eject
diska /tmp/image.dsk

[PRESS F10]
DIR

and end up with:

Disk error reading drive A
Abort, Retry, Ignore

With CP/M, the best result I have had is "NO FILE".

Man, I first tried:

openmsx -machine Spectravideo_SVI-728 -ext Spectravideo_SVI-707 -diska ../koe/4/MSXDOS17.DMK -ext Sony_HBD-F1

[PRESS F10]
diskb /tmp/image.dsk
[PRESS F10]

c:
dir
No file found! And before the "diskb" command I got Abort, Retry, Ignore!

But when I start openMSX with:

openmsx -machine Spectravideo_SVI-728 -ext Spectravideo_SVI-707 -diska ../koe/4/MSXDOS17.DMK -ext Sony_HBD-F1 -diskb /tmp/image.dsk
dir c:

shows HELLO.TXT is there! This works:

copy c:hello.txt a:

I will next copy all the WS.COM and related files. We're making some progress here now!

You can copy that CP/M boot disk DMK file and use it as a blank disk, after removing all files

Holy shit! I finally got the CP/M disk image for SVI MSX working after so much head banging! I cannot believe, I was a nervous wreck!

Here is the working diskdefs for SVI MSX. I will submit it to the cpmtools maintainer in case he wants to include it in the next release:

diskdef svi
seclen 256
tracks 40
sectrk 17
blocksize 2048
maxdir 64
skew 0
boottrk 3
os 2.2
end

And here is the shell script I used for testing alternatives:

dd if=/dev/zero of=/tmp/cpmfloppy${1} bs=1 count=$((170 * 1024))
mkfs.cpm -f svi /tmp/cpmfloppy${1}
cpmcp -f svi -t /tmp/cpmfloppy${1} /tmp/hello.txt 0:hello.txt
cpmls -f svi -d /tmp/cpmfloppy${1}
fsck.cpm -f svi /tmp/cpmfloppy${1}

Finally, you will need to compile this from openMSX git source tree:

openMSX/Contrib/dmk/svicpm2dmk.cc

On Linux, just this simple command will do it:

g++ -o /tmp/svicp2dmk svicpm2dmk.cc

openMSX requires the DMK conversion, but it works!

My next problem is that the Wordstar file set is too big for this 170KB floppy. I tried removing some files before copying them on the CP/M image, but I removed files that were needed. But the installer runs on CP/M, whoaaa!!!!
