This is the CP/M 2.2 assembler ASM. It has been disassembled, and presented in both 8080, and Z80, mnemonics. /ASMREAD.ME This file contains a fully commented disassembly of the Digital Research ASM assembler. I've provided it in two forms: 1) asm.asm -> using Intel 8080 ops. It can be assembled with the MAC or ASM assemblers. 2) asm.z80 -> using Zilog Z80 ops. It can be assembled with the Z80MR or compatible assembler. I would welcome your comments or suggestions. Larry A. Greene greenela@clear.lakes.com
