Using TASM - RC2014Z80/RC2014 GitHub Wiki

The Telemark Assembler (TASM) is a table driven cross assembler for the MS-DOS and LINUX environments. Assembly source code, written in the appropriate dialect (generally very close to the manufacturers assembly language), can be assembled with TASM, and the resulting object code transferred to the target microprocessor system via PROM or other mechanisms. It supports both Z80 and Z180 op codes.

The TASM User Manual describes how to use it.

TASM v3.2 is used by RomWBW on 32 bit Windows. TASM v3.1 can be used in a 16 bit DOSBOX on Linux environments. There is no relevant functional differences between these two build versions.
