The Mostek Z80 development systems I worked with ran M/OS which was sort of like Cromemco's CDOS which was sort of like CP/M. https://en.wikipedia.org/wiki/Cromemco_DOS While the Z80 had some new tricks Intel had a copyright on the 8080 assembler mnemonics so Zilog had to come up with their own. Yeah, I wasn't happy about IBM's choices but at least it was the end of the Wild West era.
