CP/M was released in 1974 while VMS was around 1977.

you are right. still, i don't think cp/m was used so much until the very late 70s, simply because microcomputers were not used so much until then. and at that time vms was far more powerful. i remember the first time i used vms compared with cp/m on a z80 - no contest.

Not really, no.

It's not that they weren't used. It's that they didn't exist yet.

The first 8-bit microprocessor, the Intel 8008, was 1972. The first chip for which CP/M was developed was the 8080 in 1974. It took a few years for mass availability.

Given that you got your years badly wrong in your first comment, did you not think "hey I should check this" before commenting again?
