A great find. Upload it please :)


I'd love to, but with Asimov basically unmaintained these days (stuff
doesn't seem to ever get out of the write-only "incoming" directory any
more), where should I send it?


Or send it to me!


Done!


Applesoft was created by Microsoft on request of Apple. Its a bit different
from
the other early Microsoft 6502 interpreters like the KIM-1 9 digit Basic or
the
PET Commodore or Ohio Scientific Basic versions. I assume on request of
Apple.


A bit different in that some more commands have been added. Some from
Integer and some new ones for Hires. But the code base is obviously the
same as that of Commodore BASIC, since it has the same obscure bug.

PRINT ""+-0

crashes them all.


Integer Basic versus Applesoft? Must have been users dropping Integer
Basic.


I was just wondering if Applesoft was maybe already in the works by the
time the original Apple II was introduced. Maybe it should've been
shipped in the A2 ROMs right from the start but didn't get done in time?
Or was it a somewhat later idea?


There's a pretty comprehensive explanation here

You'll need to read a fair bit or scroll down to the relevant part.

And, it's the initial 2.0 RAM Applesoft, as opposed to the very first version. Still rare and still worth collecting.
