Superbrain II QD

The Intertec Superbrain was an all-in-one commercial microcomputer first sold by Intertec 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 $2000.


There were several variants, including the Superbrain II, Superbrain II Jr., "QD" (quad density disk drives) and "SD" (super density) models.
