Last time I checked there were few resources on CP/M-86 Assembly programming, not so much on x86 instructions but on the system itself and its access from Assembly. So I've bookmarked these manuals I've come across which I missed in the past or were posted recently.

Nemanja Trifunovic revisits the story of why IBM went with MS-DOS instead of CP/M and discusses one important detail: why the 8086 port of CP/M was late and how much this influenced what followed.

A Short History of CP/M-86

This 1982 interview with Gary Kildall is interesting because it focuses on CP/M-86 which is little known.
It made me notice a difference with MS-DOS I hadn't thought of before. Like Unix and unlike MS-DOS, CP/M-86 shipped with a complete software development environment with tools such as an assembler, which might have contributed to the higher price.

Joy another time-sink, another CP/M BASIC!And it's supposedly based off of TDL BASIC, one of the better non-ms BASICs.
The docs seem to be in German only so I might be able to resist (I can't read German 😢)
Special for @amoroso there's also a cpm86 version...
I once spent way too long getting an early version of TDL BASIC working under CPM and then never did anything with it.
