Apple II Split Screen Demo
This is a quick demo from the credits of
Talbot Fantasy 7
It uses "vapor lock" (the floating bus) plus careful cycle counting
to show text, lores, and hires graphics at the same time, plus
play mockingboard music if available.
More info later. For now you can get the disk image here:

The souce code can be found on github in the
https://github.com/deater/dos33fsprogs repository as "credits.s"
in the split_screen directory.
Video capture on my Apple IIe platinum. The capture card has some issues,
including some sound lag:
