Hello,
Finally found a good Commodore 128 for yours truly there. Is there in our
midst a person who might have the cp/m boot disk for one? Or point me in
the right direction?
I have an original C-128 CP/M boot disk in a box somewhere. How would I
go about making an image with it? I've never had a working C-128, nor
have I ever run CP/M from a Commodore (Kaypros, mostly), so I don't know
what the low-level format of the disk is. If it's a standard format,
something like 22DISK should be able to digest it, yes?
Is there already a copy of this on funet?

No, it's a farked-up GCR format, IIRC. Commodore had multiple CP/M GCR
formats, the C64's v2.2 1541 type and the C128's types. 1571 drives can
read all of these and many CP/M MFM formats besides, which makes it
essential for a C128 if you want to use CP/M Plus on it. I personally
think that C128 CP/M+ 3.0 is the best version of CP/M out there.

Hello Ethan
On 24-Aug-00, you wrote:
The book saays that Commodore cp/m 3.0 supports several formats:
Commodore SS GCR (the standard C=64 format)
C-128 cp/m plus format (single sided)
Commodore DS GCR format
MFM disk formats:
Epson QX10, IBM-8 SS, IBM-8 DS, KayPor II,KayPro IV, and Osborne DD
I am not sure of which format is used for the system disk. I presume it is
commodre SS GCR, so it is compatible with any drive. Nothing further is
mentioned in my Programmers Reference Guide.

No, actually, I think it's the DS GCR format because you need a 1571 to
boot C128 CP/M. I don't think it can be booted from a 1541, which can only
read the SS format.
