Sony Corp. of America (Park Ridge, N.J.)

Sony invented the 3.5-inch floppy disk drive, and its first computer, the  SMC-70, was the first to use them. In fact, the SMC-70 might have been the only CP/M system to use the smaller storage devices as standard equipment. Other small form-factor drives were produced at the time, but Sony’s design was eventually accepted as standard. Sony also offered the SMC-70G, which had enhanced graphics/imaging capability and was designed to work with video editing systems.

Sony Filer was an operating system compatible with CP/M 1.4. The SMC-777 was the last non-MSX home computer Sony produced. Units with enhanced color graphics capability were designated the SMC-777C.

The company produced many MSX models, all with the nickname “HiTBiT,” which comes from the Japanese word for “people,” hitobito. Sony offered the HiTBiT in several color choices. The HB-55P and HB-75P seem to be the most common examples today. The “P” designation refers to a model sold internationally.
