High Quality Content by WIKIPEDIA articles! Compute! (ISSN 0194-357X) was an American computer magazine that was published from 1979 to 1994, though it can trace its origin to 1978 in Len Lindsay`s PET Gazette, one of the first magazines for the Commodore PET computer. In its 1980s heyday Compute! covered all major platforms, and several single-platform spinoffs of the magazine were launched. The most successful of these was Compute!`s Gazette, catering to Commodore computer users.
