An Apple ][+ computer simulation, in all its 1979 glory.  It also
reproduces the appearance of display on a color television set of the
period.

In "Basic Programming Mode", a simulated user types in a BASIC program
and runs it.  In "Text Mode", it displays the output of a program, or
the contents of a file or URL.  In "Slideshow Mode", it chooses random
images and displays them within the limitations of the Apple ][
display hardware.  (Six available colors in hi-res mode!)

On MacOS and Linux, this program is also a fully-functional VT100
emulator!  Run it as an application instead of as a screen saver and
you can use it as a terminal.
