'MASH' cast and the IBM PS/2 (1987):
IBM didn't have Alda for this ad, so they compensated by jamming just about every other member of the 'MASH' cast into the picture.
The gang also did television commercials for the doomed IBM system, showing the characters bizarrely transported from an Army hospital in Korea to a generic American office building where they apparently all inexplicably decided to continue working together. In one, Radar bubbles excitedly about the PS/2's ability to put "256 colors on the screen at once!"Eventually, Alda's love of Atari PCs proved fickle. He showed up in another of the MASH-characters-as-cubicle-drones ads for IBM's machines.
