I still have on my shelves -

Intel 8080/8085 assembly language programming, Intel Corp, 1977
William Barden "The Z-80 microcomputer handbook". Indianapolis, Howard
W Sams, 1978.
Willian Barden "TRS-80 assembly language programming", Fort Worth,
Radio Shack, 1979.

I bought a TRS-80 in 1978 which had 4k of RAM which I upgraded to 16k
and it also had 16k of ROM which had all of it's software. Mostly a
Basic interpreter..
