The Sharp PC-1211 is the first pocket computer ever released, marketed by Sharp Corporation in March 1980. The computer was powered by two 4-bit CPUs laid out in power-saving CMOS circuitry. One acted as the main CPU, the other dealt with the input/output and display interface. Users could write computer programs in BASIC.
A badge-engineered version of the PC-1211, the TRS-80 Pocket Computer (model PC-1), was marketed by Radio Shack in July 1980 as the first iteration of the TRS-80 Pocket Computer with just a marginally different look (outer plastic parts in black, not brown, gray display frame)
