There are probably copies in the warehouse. If you need help looking for them during the Workshop, let me know.

Hello all, If anyone has a CP/M master disk or any other Commodore CP/M disks for the Commodore 128 I'd like to try preserving them with the Applesauce in the museum. I am bringing a bunch of GCR and MFM disks to test the latest version for other computer models. Thanks, Eric

I'll do a quick look in my own collection before I leave for the workshop today, and bring it if I find it. However, if we have at least one boxed C128 in the warehouse, odds are that it contains a C128 CP/M disk.

Didn't Dean send one to Bil Herd recently? Maybe he has another that he can bring this weekend.

Be advised that I think there were tweaked improved versions produced.

Very interesting. I wonder if someone has tracked all the versions and differences.

If someone has, I would like to know. I have a (vintage) CP/M program that works fine on one version of the C-128 CP/M disk and doesn't work on another and I've hesitated sharing it until I see more evidence of reliability. In particular, there's a BDOS call to get a menu prompt from the user and on an Altair emulator and CP/M 1.4 it works fine. On the C-128 with CP/M Plus, I had one disk image where it worked and one where it froze. It's a really basic call to read a single char from the console device. It _should_ just work. I was not successful in tracking down the source to that call to see how it was implemented on the C-128. I would love to see some sort of list of what was out there so I can get a handle on the scope for further testing. -ethan P.S. - it's related to the theme for the upcoming VCF East so I'd like to get this working.
