[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 2.3.7nb1, Package name: z80-asm-2.3.7nb1, Maintainer: pkgsrc-users

z80-asm is a double pass compiler of the Z80 CPU assembly language.
It supports almost all of the Z80 opcodes and functionality that
commercial Z80 assemblers have. This package also contains an
interactive Z80 disassembler. This program suite was written by
BrainSoft.
