What features do you want or need in an 8080 disassebler that you haven't been able to find? I recently went looking for 8085 disassemblers for the monitor ROM in an HP 5036A microprocessor trainer. I didn't like much of what I found either and I ended up just writing my own. It really wasn't that difficult and had the benefit of being able to exactly control the listing format as I wanted. _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
