This section covers the operation of the Master Controller (MC) and the other different units that comprises the LC-81 minicomputer.

Click to selectMaster Controller Console
The Console provides the very first mean for operating the LC-81 minicomputer. Using the Console, the operator can start and stop a program from given address, examine and modify memory and I/O content, allow or disallow Interrupt and DMA requests from peripherals and to monitor several CPU status signals.

Worth to mention, the Console operates based on hardwired logic independently from the microprocessor (that is, without software assistance) except for the START button functionality which utilizes a little program (seven bytes of machine code) contained into the MC EPROM.
