  • AVOCET SYSTEMS Z80 ASSEMBLER

    From Nathanael@cjeculver@gmail.com to comp.os.cpm on Wed Dec 13 02:34:36 2023

    Over at Github, erkyrath has recently put up the source code of the Infocom game interpreters for many systems, including CP/M. The cpm80 source code is accompanied by a .PRN which reads "AVOCET SYSTEMS Z80 ASSEMBLER - VERSION 1.03C."

    Does anyone know of a source for this assembler?

    Thanks to Steven Hirsch for putting me onto the 2500AD assembler/linker, which is essentially the Avocet assembler. I only ran into a single issue, which involved a change at line 4041 from DB $27, $22 to DB 027H, 022H. A binary compare on the output with an existing .COM file found it basically byte-identical.
    This is Version C of the Infocom interpreter. I'm wondering if source for the previous two versions could be reconstructed from this.
