Softalk Nov 1981 writes Tank Command was first revealed at the West Coast Computer Faire held on March 1980 in San Francisco. The brothers were in full gear in time for the 1980 West Coast Computer Faire. They took a microbooth to display their three TRS-80 programs in the Saga series, as well as a [Apple II] lo-res Tank Command written by their brother Don.

In the Internet Archive emulator, type "R" "K" to run the title.

The original game has a briefer copyright notice.
