I found an 8-inch floppy disk labeled with "CP/M V2.0 9/4/79" which is crossed out and replaced below with "CP/M V2.1 7/13/80". I don't see mention of version 2.1 at http://www.cpm.z80.de. Do I have something unique? Who can I trust to image this and put the contents on the net?
DRI released several updates to 2.0 to OEMs. I think I still have the update bulletins somewhere. I don't know if I still have the code itself. It was a comparatively short period before 2.2 was released.
I don't recall if the result was 'officially" called 2.1 or not. --Chuck
