1)  Blackout.  Turned the screen colors to Black, black, black.  Turned
sound to zero, boot disk to ROMdisk (I think!).  Installed in block
zero of boot disk.  System 6 made it impossible for it to install itself.

2)  Lode Runner

3)  CyberAIDS

4)  Festering Hate

Blackout is the only one which intrigued me; it's very similar to some
of the early programs I wrote.  Very simple, yet damning.  I did write
a simple (BASIC) program long ago (DOS 3.3) which would zap all screen
output upon bootup, but I never learned enough to play with 1) reset
vectors, and 2) Ctrl-C (ONERR) handling.

The virus reminds me of someone who got too much information too soon
and decided to fiddle.
