Demon Attack (Imagic) on the IBM PCjr

A quick demo of Demon Attack running on an IBM PCjr ...
Imagic ported Demon Attack to the PCjr in late 1983 or early 1984. It is a basic "shoot any alien that moves" type of game with pretty decent graphics and excellent sound. This demo shows the cartridge version of the game which works on any PCjr including those without a diskette drive. Space on the cartridge is in short supply so Imagic could not put a title screen up before the game starts!
The game looks much better on a real RGB monitor. This capture was taken from the composite port on the back of the machine which is better than shooting a camera at the screen but not as good as the RGB signal.
