The PROFI-5 family of microcomputers includes different versions of a single-board computer that came onto the market in 1981 and was further developed later. It is mainly used in training and inter-company training. It is available in the variants PROFI-50, PROFI-5, PROFI-50E and PROFI-5E.

The MICO-80 microcomputer system is functionally compatible with the Profi5E, but equipped with a Zilog Z80 microprocessor .

history

The PROFI-5 was developed by the Kammerer engineering office in 1981 and marketed as the successor to the EZ80-DIT learning computer .

PROFI-5E microcomputer in plastic frame

From 1994 to 2011 the successor device PROFI-5E was sold by IED Kammerer GmbH, Germany. Depending on the version, this single-board computer is based on the 8-bit microprocessor Intel 8080 (PROFI-5 / PROFI-50) or on the Intel 8085 (PROFI-5E / PROFI-50E). The size of the main memory in the basic configuration is 2K - 8K byte ROM and 1K - 4K byte RAM, expandable up to a total of 22 Kbytes. The interfaces are single-bit programmable input / output lines ( Intel 8255 ), a parallel Centronics interface (PROFI-5E / -50E), a serial V.24 interface and, for extensions, an SMP bus (PROFI-5E / - 50E) available. A tape interface is built in for the analog storage of programs and data.

The systems of the PROFI-5 microcomputer family have a monitor program in the ROM . This enables program and data to be entered in hexadecimal code , processing in single-step and automatic mode, display and editing of the register contents. It is operated using nine function keys, and data is entered in the hexadecimal system using 16 keys labeled with the numbers 0..9 and A..F. The reset button enables a cold start.

An 8-digit seven-segment LED display is available as a display . Alternatively, it can also be operated via a terminal connected to the V.24 interface.
