Tandy/Radio Shack Advert - August 1979
From Personal Computer World
"New low price for Level 1 BASIC 4K RAM"
The TRS-80 was one of the "1977 Trinity" - which also included the Commodore PET and the Apple II. Legend has it that Chuck Peddle (inventor of the 6502) approached Radio Shack (owner of the Tandy name) as a potential outlet for his PET machine, but that RS said they were uninterested, only to take the idea and produce a machine of their own. For a while it was the best-selling of the three, and came in several forms, including a keyboard-only version. This combo retailed for £431 - about £2,100 in 2011 prices, making it cheap compared to the PET and the Apple II.
