When the TRS‑80 Model I was introduced on August 3, 1977, it came with Level I BASIC, a 4K BASIC interpreter, in ROM. Level I BASIC was created by Steve Leininger, the designer of the TRS‑80, who based it on the public domain “Palo Alto Tiny BASIC” that Dr. Li-Chen Wang wrote in 1976.

But Radio Shack’s plan was always to upgrade to a more advanced Model I BASIC later. The very first TRS‑80 brochure said that “planned expansion includes an extended Radio Shack Level II BASIC.”
