Basis was a European distributor for Apple until the company decided to set up its own sales operation on the continent. Basis’s response was to build and sell what it believed to be a better Apple II. The company set up a U.S. subsidiary in California in1982. The company headquarters appear to have moved to Hong Kong by the time it produced the oddly named Medfly system. Basis also made the Basis 203 CP/M systems and the Xenix-based Basis 216. The Basis 216 was unusual in that one of its processors was the seldom-used Zilog Z8001.
The dual-processor Basis 108 was hardware and software compatible with the Apple II and could also run CP/M applications. The 108 looked more like a typical CP/M machine than the Apple II, with a separate keyboard and an optional monitor in a retro-looking swivel frame. At least 25,000 Basis 108s were produced.
At the system level, the Medfly seems identical to the 108. A redesigned keyboard and ivory-color enclosure replaced the 108’s beige components.
