In the early 1980s, Messina Electronics designed and manufactured a micro-computer, based on the eight bit Motorola µ6800 micro-processor. This micro-chip operated at either 1MHz or 2 Mhz clock.

The so called "Commander" micro-computer, was programmed using a Basic-like Process Control Language (PCL) developed in-house using the Motorola Assembler. PCL featured very specialised Real-Time functionality, targeted at software development for industrial applications.

The Commander peripherals included 10MB Pertec Cartridge Disk Drives, 8" flexible diskettes and a cassette tape.

The "Commander" conquered the South African market, competing against the (later giant) "Apple II" and was installed in industrial "Turnkey Process Control" applications at Mines, Breweries, Sugar Mills, Soap manufacturing factories, Truck engines production and in office type applications, like Accounting and Inventory Control.

Messina Electronics also manufactured "water level detectors" for the South African military industry. The innovative design of these units involved the manufacture of a hybrid circuit and some high quality encapsulation technique, within military standard enclosures.
