PET Support #9

Would PET support be possible? BASIC would have all the same IEEE routines, but they're at different locations.

If it were possible, I have an MTU graphics board and could do a kiiller analog clock for the PET! But I need floating point :-)

Random trivia: Bill and Paul thought the floating point was going to be really hard, and they were talking about it at lunch in their dorm cafeteria. One of their friends scoffed that it'd be easy, he'd done it before!

His name was Monte Davidoff, and Bill and Paul called his bluff and hired him to write the floating point routines for BASIC (8080 originally). I got to chat with him a while back when I was researching the history of the floating point code. Long story short, it mostly comes from what he learned looking at a FOCAL interpreter.

As far as I know, Ric Weiland did the 6502 port.

Sure, why not - someone would have to port it :)
