Hallo allemaal,

First, the CP/M disks for the CBMs can be found here:


Then FYI: except starting up a boot disk or a program I didn't do 
very much with CP/M on the C128. Therefore quite some lack of 
knowledge. Please, bear with it :)

Three question:
- I more or less always thought that C128 CP/M disks were a mix of 
Commodore's GCR format and one or another MFM format. But the first 
disk I tried to create an image of turned out fine. Second disk, a 
CP/M boot disk: fine as well. third disk, another boot disk: nope. 
But as D64 it turned out fine as well. The question: what is normal?

- Is there a quick way to find out whether I'm dealing with a D64 or 
a D71? I know tell the program to treat the disk as a D71. It first 
reads track 1 and then 36. If that goes wrong I know enough. But the 
time consuming part is Ctrl-C and resetting the ZF by removing and 
reinserting the USB plug.

- Opencbm provides the tools for displaying the directory. But not 
for CP/M disk AFAIk. Neither CbmXfer. Unless I overlooked something. 
I have run and still run in various CP/M disks were the text on the 
labels faded away. Is there a tool to see their director?

Many thanks in advance!

Kind regards / Met vriendelijke groet, Ruud Baltissen
