This computer was never sold in computer stores. It is an homebrew machine built around an unique board called PROF80.
The Prof 80 was a CPM Board for CP/m 2.2 or (later) 3.X., manufactured by Conitec, Dieburg, Germany. There is also a branch in US. The company still exists, and the chief designer of the board, Joachim Hanst, is still working there.
It was sold in France in kit form by the Pentasonic stores chain. User had to solder all the components onto the bare board.
The PROF80 board was fully compatible with the Tandy Trs-80 MOD III, and featured 64 KB of RAM, serial and parallel ports, floppy drive controller, video and tape recorder interfaces and a GRIP (Graphical IO-Processor). The Basic interpreter was the LNW version.
Various systems were designed by private persons around this board, mainly in Germany. From simple training computers up to complete professional system.
The version pictured here was very carefully built from an old video terminal. It featured some enhancements allowing the use of the 8" floppy disk drive as well as graphic capabilities.
