The Applevision program was actually written in 6502 machine language.
However, back then it was very common to embed machine language programs
in Integer Basic program files, and Applevision was one of them.
One thing that I've always wondered about the AppleVision program, was
how the "HOME SWEET HOME" text was placed in the middle of the HIRES
screen. If I remember correctly, the only way to quit AppleVision was
to hit the RESET key, which dumped you out of HIRES mode. But when
you did that, the "HOME SWEET HOME" text was still there. As far as
I know the only way to mix HIRES and text was at the bottom of the
screen.
Anybody know how that particular piece of magic was accomplished?
