Source: Compute! – Issue Number 18 – November 1981
Compute! was one of the better multi-format computer magazines of the 1980s (and early 1990s). In 1981, Compute! was focused on computers based on the 6502 CPU. At the time, this included the Commodore PET, Atari 8-bit and Apple II in addition to more obscure entries like the KIM and others. The November 1981 issue includes:
