Hello Liam, hello Tom,
And according to the mainstream account (?), CP/M-86 would not be released until late 1981. QDOS was released earlier, in mid-1980 (https://archive.org/stream/byte-magazine-1980-08/1980_08_BYTE_05-08_The_Forth_Language#page/n173/mode/2up).
QDOS's system call interface (`call 5') was in fact based on that of the _8O8O_ version of CP/M, while CP/M-86 decided instead to implement a different syscall interface (`int 0xe0').
I misspoke a bit here: `call 5' was just one of QDOS's system call interfaces (the other syscall interface supported by QDOS would be the `int 0x21' that MS-DOS programmers are familiar with).
