If you like I can provide the CP/M Plus source code with support for the Dobbertin hard-disc.
Thanks. For now I will not need it, as if I ever do it, it wont be anytime soon

- Noted 2 persons are interested!
In the ROM-List of Web-Frontend, there are buttons "Remove" / "Upload".
Is it possible to add "Disable" / "Enable" and see the actual status of the Rom ("enabled")?
Sure.
You can already use |romset,romnum,0 to disable a rom and |romset,romnum,1 to re-enable it. Will add it to the web-interface when I give the rom part a needed overhaul anyway.
2 compatibility-questions:
- M4 + XMEM:
I can't get it together. I've tested:
Switch M4-Config-Site - switch off "Enabled".
XMEM: The ROM-Active-Jumper: Change it on every possible position.
(maybe interesting: without M4 and open jumper on the XMEM, the ROMS are partial loaded (Screen corrupt, but e.g.|maxam works)).
- Has anyone the M4-Card and ACMEDOS with a CF-Card in use?
I only can get them to function, if i use a DOM instead of a CF-Card.
Without M4 and with XMEM the CF-Card works
M4 + XMEMThe normal way, would be to disable romboard function of XMEM, using the the "Read ROM" jumper, setting it to no.
However if you have a CPC where you can replace ROM7 (ie. 464/464+/6128+), you can set M4 rom to 7 and make no other roms are uploaded (M4 will only drive roms that are uploaded and enabled).
Thus you could use the roms of the XMEM instead, which does not drive ROM7.
You can also move the M4 romboard start position to 32, so the roms come right after XMEM roms, but you will need the M4 to be initialized somehow to use mass storage (ROM7 would work if possible).
If you switch off enabled in "ROMS" setup of M4, that means M4 rom will not be enabled.
M4 + XMASSNot having an XMASS, I haven't done any tests, but the logical way to do it, would be:
M4 < XMASS < AMSDOS
Ie. M4 rom to 5
Xmass (acmedos) rom in 6
AMSDOS in rom 7
Now when you boot up, M4 will have the amsdos jump vectors (last initialized), if you do |disc, you theoretically should shift to XMASS. Use |SD to switch back to M4.
Hmm probably not what you asked, CF-card vs DOM, maybe a power consumption issue?
