Hope this is not too OT...
Just to let you know that in the long list of different modules for my
Linux Xscreensaver (on Mdk 10.1) there's one named APPLE2.
The description (from the docs) is:
Simulates an original Apple ][ Plus computer in all its 1979 glory. It
also reproduces the appearance of display on a color television set of
the period.
In "Text Mode", it displays the output of a command (e.g., "fortune".)
In "Slideshow Mode", it chooses a number of images from the image
source you configured into XScreenSaver and displays them within the
limitations of the Apple ][ display hardware. (Six available colors in
hi-res mode!)
In "Basic Programming Mode", a simulated user types in a BASIC program
and runs it.
