Invasion Force

Invasion Force (catalog number 26-1906) was one of the first action games Radio Shack published for the TRS‑80 Model I. It was written by Robert Arnstein and introduced in 1979 on cassette for a price of $14.95. There never was a disk version of Invasion Force.

Invasion Force was very similar to Trek-80, a game for the Sol-20 computer that was probably also written by Robert Arnstein.

Talking Eliza

Eliza (catalog number 26-1908), also known as Talking Eliza, was a TRS‑80 Model I and Model III implementation of Dr. Joseph Weizenbaum’s famous ELIZA program. It was introduced by Radio Shack in 1979 for a price of $14.95. Eliza was written by Robert A. Arnstein and was licensed to Radio Shack through his company, Device Oriented Games. One unusual feature of the program was its ability to speak its responses using Radio Shack’s TRS‑80 Voice Synthesizer, hence the name Talking Eliza.
