The Intertec SuperBrain was an all-in-one commercial microcomputer that was first sold by Intertec Data Systems Corporation 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 $5,880 in 2022).
There were several variants, including the SuperBrain II (released in 1982), SuperBrain II Jr., "QD" (quad density disk drives) and "SD" (super density) models.
Intertec also released a similar looking dumb terminal, the Intertube, and smart terminal, the Emulator.
The SuperBrain is notable for being at the user end of the first Kermit connection in 1981.
The machine was practical and useful in the office environment, but somewhat limited until the arrival of the first 5 MB hard drive in one of the floppy drive bays. This was soon replaced by the 10 MB hard drive.
Up to 255 CompuStar workstations could be daisy-chained together via DC-37 "Chaining Adaptor" parallel ports to share the "central disk system" (one of the three hard drive peripheral options below). Each computer, or VPU (Video Processing Unit), was assigned a unique number from 1 to 255 by setting an eight-position DIP switch.
