Great news!
The question now is, does this also work with the SVI-738 which also can run CP/M, but using a 1DD 3.5" disk type.

Otherwise you should perhaps have called it diskdef svi707 to distinguish between the two..
Yeah, I was thinking about the proper naming, and indeed thought of svi707! But I already submitted the patch using name "svi"...Damn! I am not an expert, but probably this disk definition is specific to SVI-707.
The older non-MSX SVI 3x8 system could also run CP/M, perhaps the SVI707 disk format is compatible with it. I know openMSX has some support for emulating these older 3x8 systems, but not sure about the disk drive support for it.
The PTC had licensed Wordstar Calcstar Reportstar and Mailmerge in their programs for MSX2 even to convert it to Homeoffice and vice versa.

Okay. I actually have a real, physical Spectravideo SVI-328, but I have never tried it. I know it is a very important machine historically, because it served as a basis for the MSX1 standard.
I just tried SVI-328 emulation with:
openmsx -machine Spectravideo_SVI-328 -ext Spectravideo_SVI-707 -diska CP224R13.dmk
It beeped and booted to BASIC, not to CP/M. I used svi-3x8_v111.rom.

I see. Perhaps there is no Wordstar suitable for MSX1 machines. I don't know, but I guess I will find other CP/M programs that will run on SVI-728/SVI-707. If I cannot run Worstar, surely there is something else.
openmsx -machine Spectravideo_SVI-328 -ext Spectravideo_SVI-707 -diska CP224R13.dmk
It beeped and booted to BASIC, not to CP/M. I used svi-3x8_v111.rom.
Maybe SVI-328 needs SVI-902 floppy drive. But I guess that one is not emulated by openMSX.
On a 728 with 707 +727 booting CP/M gives 80 colums.
Then starting with wordstar on disks of an svi 605a should work.
An nice setup.
I will try this evening.
openmsx -machine Spectravideo_SVI-328 -ext Spectravideo_SVI-707 -diska CP224R13.dmk

Indeed, the SVI-707 is definitely not going to work with a SVI-3x8. You need something like the SVI-902 or the Super Expander I think.
There is an expanded 328 machine config in openMSX with diskdrive included.
The 328 plus an SVI 605 has the option to start SV extended Disk basic or CP/M
The 601 has this option too.
