It was one of the first mass-marketed, fully-assembled microcomputers and quickly became the best-selling personal computer.

Yet despite continued demand, Radio Shack discontinued the Model I on January 1, 1981, slightly less than three and a half years after it was first introduced. The culprit was not customer demand (which remained high) but new radio interference regulations from the United States Federal Communications Commission (FCC) which took effect on that date.]]> http://www.trs-80.org/why-was-the-model-i-discontinued/feed/ 3
