Unlike the two earlier computers, its design was influenced by the IBM personal computer. Because of some additional functions in the ROM and different graphics routines, the MPF III was not totally compatible with the original Apple IIe computer.<ref name=":0" />
One key feature of the MPF III in some models was its Chinese BASIC, a version of Chinese-localized BASIC based on Applesoft BASIC.
The MPF III included an optional Z80 CP/M emulator card.<ref name=":1" /> It permitted the computer to switch to the Z80 processor and run programs developed under the CP/M operating system.
In 1984 the machine had a retail price of $699 in Australia.<ref name=":1" />
The different models in the MPF-III brand were the Multitech MPF-III/311 in NTSC countries (mainly in the United States and Canada) and the MPF-III/312 in PAL countries (mainly in Australia, Sweden, Spain, Finland, Italy and Singapore). It was also sold in Latin America as the Latindata MPF-III.<ref name=":1" />
