mpf1 00mpf1 01The Microprofessor I (MPF-1), introduced in 1981 by Multitech (which changed its name to Acer in 1987), was the first Multitech-branded computer and one of the longest-selling computers. The Microprofessor I consists of an electronic board based on the Zilog Z80 processor: it is designed to teach the fundamentals of machine language and assembly. The Microprofessor I does not have the appearance of a classic microcomputer: it is enclosed in a sealed book-shaped plastic casing that can contain the language manual, 2 cassettes and a learning manual. When closed, it has the appearance and dimensions of a book and can therefore be placed in a bookcase or carried with you comfortably.
