surely not - i used cp/m 1.x back in the late 1970s and by that time VMS was a well-developed and sophisticated OS, unlike cp/m which was something you could have knocked up in a week or so.
- InfamousRece 3y agoCP/M was released in 1974 while VMS was around 1977.
- zabzonk 3y agoyou 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.
- lproven 3y ago> simply because microcomputers were not used so much until then 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?
- atombender 3y agoAccording to Wikipedia, CP/M was released in 1974, and VAX/VMS was "announced" in 1977 (presumably means it was available a bit later than that).
- ewgoforth 3y agoI always thought DOS got the backslash from VAX/VMS, a question which this article seems to avoid asking.
