Microprofessor III
From Wikipedia, the free encyclopedia
Microprofessor III (MPF III), introduced in 1983, was Acer's (then known as Multitech) third branded computer product and also one of the first Apple clones (an Apple IIe clone). Unlike the two earlier computers, its design was influenced by the IBM PC computer. Because of some additional functions in the ROM and different graphics routines, the MPF III was not totally compatible with the Apple IIe.
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. It permitted the computer to switch to the Z80 processor and run programs developed under the CP/M operating system.
