Viatron's System 21 was the computer of the 1970s! ...At least that's what their marketing claimed. Started in 1967 Viatron was set to be one of the most exciting companies of the coming decade. They were offering a desktop sized computing machine, the System 21, that promised to break IBM's domination of the office. The System 21's heart, the so-called "micro-processor", was slated to be built from cutting edge LSI chips. It could automate data processing, replace bulky IBM hardware, and do away with the punch card. And this marvel could be yours for just $39 a month. Sounds like a good deal, right? Maybe too good. According to some Viatron was strait up stock fraud.
