Herb; ASM will take tdl mnemonics except for the non-8080 z80 instructions; (that's because tdl starts with the intel 8080 instruction set & adds more --in the same style-- to cover the extra instructions used by the z80). If you try assembling them, you will get an error message; If you really want to, you can then translate the z80 instructions into 8080 instructions. (there are macro's for doing this with the MAC assembler). Most software that doesn't explicitly require a z-80 to run use only the 8080 instruction set (which is also compatible with 8085's): So when these are disassembled to tdl mnemonics, the disassembly should contain only the intel mnemonic 8080 instructions. This means you won't have to do any z-80 translation. REZ runs on z-80's under cpm. I think Christiansen wrote it in 8080 assembler so it should run on 8080's and 8085's too. George
