Reliability in the toughest environment The 6020 PC microcontroller is a 386–powered Micro ™ PC computer with the essential I/O functions for embedded applications. It integrates serial ports, digital I/O, LPT1 and floppy drive (through LPT1) into a single card. The 6020 is ideal for applications in transporta- tion, security, military, communications, distributed con- trol, point–of–sale, ticketing machines, weighing equip- ment, and other similar applications.

It supports key- board, mouse, and other PC peripherals. The BIOS also has additional Octagon BIOS extensions for watchdog timer, serial EEPROM access, and user jumper. At power–on, the BIOS performs a Power–On–Self– Test (POST) and outputs the results via an LED.
