This is driving me nuts. I am certain I have a downloaded scan of the source code to the 6502 ML monitor Woz wrote, but pre-dating Apple's use of the monitor. I even remember there was some text like "a 6502 monitor you can use for your projects" or something to that effect. It was published somewhere - maybe in Popular Electronics, or in a Homebrew newsletter, or a really early computer magazine... But I'm drawing a total blank, and googling for '6502 and Woz and Monitor' isn't helping me at all.

Note, I am not referring to the code printed in the Red Book or subsequent Apple documentation.

Can anyone cite where the code for his 6502 ML monitor was first published?

Ok, I found the image I had formed in my mind - it was from Dr. Dobbs Journal, Volume 1, Number 8, 1976. - But my memory was wrong about pre-dating Apple. The article is actually titled "A 6502 Disassembler from Apple by Steve Wozniak and Allen Baum".

    The apple floating point routines are in the previous issue.

  • I think I may have that in a box somewhere in the garage. I'm pretty sure that it was in Dr. Dobb's Journal of Computer Calisthenics & Orthodontia (the full name at the time: computerhistory.org/collections/catalog/102660981). The motto was Running Light without Over Byte or something like that
