Microbee PC85 computer and circuit board

Object No. 2013/94/1

The Microbee PC85, despite its unassuming appearance, represents a zenith in the success of computing in Australia in the 1980s. The PC85 was designed and manufactured by the Microbee Systems company, which just half a decade earlier, was a shop front in suburban northern Sydney selling electronics supplies to hobbyists. The PC85 was developed to directly compete with Apple computers, Commodore computers, and other US giants such as IBM, and considering the vast differences in financial backing, Microbee were quite successful. The PC85 had a user friendly, full colour interface and included nine programs as standard - MicroWord BASIC, Help ROM, Wordbee, Telcom, Self Test Program, Calculator, Machine Code Monitor, and PC85 Menue Program. It was also designed to be a multi-purpose computer - used for study, business and gaming. In the mid 1980s, Microbee was a smart and successful Australian enterprise, publishing computing literature, and expanding into the northern European, Asian and Russian markets. The company Applied Technology, once the entrepreneurial and technical talents of Owen Hill and Matthew Starr in particular flourished, quickly evolved into a large and progressive business which was designing and manufacturing affordable computer technology, with a philosophy of engaging the client after sale. Owen Hill secured contracts to supply the Department of Education with Microbee computers, and further, contracts with Swedish, Asian and Russian schools. Microbee Systems, as the company called itself from the early 1980s, was a victim, along with the majority of computer manufacturers world wide, of the IBM clone computer, and Microsoft establishing widely accepted compatibility with its software. Once again though, the Microbee has become the interest of hobbyists interested in vintage computers and software. Damian McDonald Curator September 2013

PRODUCTION

Notes

This computer was designed and manufactured by Microbee Systems, formerly Applied Technology, in Gosford, New South Wales, Australia, in 1985. This particular unit was the last Microbee PC85 to have been produced.

HISTORY

Notes

This Microbee PC85 was kept by Owen Hill, who in 1978 began work at an electronics supplier - Applied Technology - and built a computer he had designed. The kit computers Mr Hill designed were popular with hobbyists, but at the same time Apple, Commodore and several other US companies were selling complete computer systems, which negated specialist computer knowledge, and thus were selling to a much wider market. In 1982, fully assembled Microbees were on the market, and, with the assistance of Department of Education contracts, the company expanded greatly. A factory was opened at Gosford in New South Wales to manufacture Microbee computers, and the company continued to expand. Mr Hill kept this particular PC85 because it was the very last Microbee PC85 to be manufactured.
