COMPUTE!’s Telecomputing on the Commodore 64 is a 1985 COMPUTE! Publications guide that introduces Commodore 64 users to telecommunications with a modem, covering the basic concepts, terminology, hardware, software, and online services needed to communicate with other computers over phone lines. It explains modems, ASCII, RS-232, data transmission, bulletin board systems, commercial information services, uploading, downloading, and file transfers, while also discussing broader topics like telecommuting and online research. The book includes practical terminal software for the Commodore 64—TeleTerm 64, Termulator, and Plus/Term—along with appendices for online services, typing in programs, the Automatic Proofreader, and MLX, making it both a beginner’s telecomputing primer and a hands-on software guide.
