Keyboards
After the introduction of the IBM PC, Keytronic began manufacturing keyboards compatible with those computer system units.
Most of their keyboards are based on the 8048 microcontroller to communicate to the computer. Their early keyboards used an Intel 8048 MCU. However, as the company evolved, they began to use their own 8048-based and 83C51KB-based MCUs.
In 1978, Keytronic Corporation introduced keyboards with capacitive-based switches, one of the first keyboard technologies to not use self-contained switches.
