What Happened on August 3rd

Radio Shack announces its TRS-80 Model I, the company's first personal computer. Equipped with 4KB of RAM, cassette-tape storage, and a built-in BASIC interpreter, the TRS-80 was one of the first mass-marketed personal computers (along with the Commodore PET and Apple II). At a time when most microcomputers came in kit form and appealed to hobbyists, these three computers addressed the average person and were very popular in schools.
