The "Trash-80" Personal Computer
1977

TRS-80
Affectionately known as the "Trash-80," this PC was introduced by Radio Shack in 1977. The TRS-80 had only four kilobytes of memory, however, and could not handle lowercase letters. What's more, it had just three error messages: "HOW?" whenever the user tried to perform an illegal function; "WHAT" when a syntax error occurred; and "SORRY" when the available memory ran out. Still, its price--$400--and its availability made it one of the most popular of the early personal computers. Some 55,000 machines were sold in its first year.
