The company's first branded product, it was marketed as a training system to learn machine code and assembly language for the Zilog Z80 microprocessor.

In 1981 Multitech released the Micro-Professor MPF-I, a Zilog Z80 microprocessor development board enclosed in a vacuum formed plastic bookcase for storage on a bookshelf.

One is used to read the drive and the other is used to write data; on a conventional audio cassette deck the wires would be connected to the headphone and microphone ports.

PicoRAM 6116 is a 6116 SRAM emulator and SD card interface for the Microprofessor based on the Raspberry Pi Pico.
