Subject: Re: RESOURCE and REZ...

Herb;
       It is my understanding that the commands for using rez and resource
are (for the most part) identical; rez was, as I recall, developed by modifying
resource. Try the rez doc's instructions. 
       If all else fails, use rez and one of the public-domain z80 assemblers;
chances are that what you are disassembling only uses the 8080 subset of z80
instructions anyway, and zilog mnemonics are easy to learn. One version of
rez (or is it an option rez offers -- I can't recall) produces TDL mnemonics,
which are intel 8080 mnemonics with intel-like extensions to cover z80
instructions.
