The Intertec SuperBrain was an all-in-one commercial microcomputer that was first sold by Intertec Data Systems Corp. of Columbia, South Carolina, USA in 1979. The machine ran the operating system CP/M and was somewhat unusual in that it used dual Z80 CPUs, the second being used as a disk controller. In 1983, the basic machine sold for about US$2,000 (equivalent to $5,440 in 2021). There were several variants, including the SuperBrain II (released in 1982), SuperBrain II Jr., "QD" (quad density disk drives) and "SD" (super density) models.
