In the documentation for YAZE-AG it mentions making changes to enable CP/M 3.1 to be run but actually ships with ZPM3N10, a free replacement. Looking through the network of CP/M related pages including JGH's CP/M page on mdfs.net and The Unofficial CP/M Web site, I can find no other mention of it.
I do find CP/M+ mentioned, aka. CP/M 3 but looking at the Digital Research source from The Unofficial CP/M Web site that appears to be version 3.0.
Does anyone know anything more about it? Is it published anywhere? Was it every widely used? What are the differences from 3.0?
And, while we're at it, was any version of 3 widely used or much software written for it?
Talk about non-Acorn classic computers/hardware/software here (including retro consoles)
