I think I read somewhere than the inspiration for the CP/M commands was
RT-11, not TOPS-10. But, anyway, the RT-11 commands _are_ inspired by
TOPS-10, which. by the way, sound a little bit like OS/8... :)

I haven't read the article (yet), however I'm pretty sure I've seen in the past that CP/M was indeed inspired by TOPS-10, and nothing else.

God knows if I can dig up any sources of that, though...


The wikipedia is not a 100% reliable source, but...

"CP/M's command line interface was patterned after the operating systems from Digital Equipment, such as RT-11 for the PDP-11and OS/8 for the PDP-8."

Yeah, in this case I'd take Wikipedia with a large grain of salt...

Actually, also, if you look further down the Wikipedia article on CP/M, you'll find this:

"Various aspects of CP/M were influenced by the TOPS-10 operating system of the DECsystem-10 mainframe computer, which Kildall had used as a development environment."

Isn't it wonderful how you'll find contradictory information even within the same article. This latter quote however, provides references...
