CLOAD was a magazine on cassette for the TRS-80 Model I computer, and was a forerunner of the later concept of disk magazines. It began publishing in March, 1978, by founding publisher Ralph McElroy and editor Dick Fuller. Its name was from the command used in TRS-80 BASIC to load a program from a cassette. David Lagerquist became editor-in-chief of CLOAD Magazine in July 1980. It continued publishing until at least 1984, and was joined by sister publication Chromasette, for the TRS-80 Color Computer. In October 1982 it was made available on floppy disk as well, making it a true disk magazine.
