The MPF-1 (MicroProfessor 1) was a computer system specifically designed by Multitech (now known as Acer!) as a learning tool for use in the teaching of microprocessor, microelectronics, and control technology. In the 80's it was sold as an Z80 CPU learning and initiation system, and believe it or not, it is still in production and sold by http://www.flite.co.uk/.

The capacities of the system were quite poor. The standard model could be programmed only in machine code through a small hexadecimal keyboard. When sold in it's original package it had the particularity to look like a book when closed.

There was an EPROM socket, which can be compared to a cartridge slot. A mini-Basic EPROM and some other utilities and languages were available as options.

There are in fact two models: MPF-1 (later called MPF-1A) and MPF-1B. The MPF-1(A) is machine code programmed only whereas the MPF-1B offers a really crude version of BASIC (one button = 1 command, as per the early TRS-80) in addition to the machine code capabilities.
