The MPF 1P (MicroProfessor 1 Plus), is an improved version of the MPF 1. Like its brother, it is a learning tool for use in the teaching of microprocessor, microelectronics, and control technology.
It has a better keyboard. Instead of the hexadecimal keyboard of the MPF 1, this one is a real "QWERTY" one, with CONTROL and SHIFT keys. There is even a RESET key at the top right (red key).
The VFD display is also larger. It can now display 20 characters instead of 6 with the MPF-1. It's a 14 segments blue Vacuum fluorescent Display. The color is that typical blue-green and had very high readability. Blue VFD was relatively new technology, first appearing in labs around 1980
The main board has also been redesigned and the RAM capacity is of 4k on the standard model.
Despite its poor features, the MPF-1P had great expansion possibilities with an input/output control memory expansion (IOM-MPF-IP), an optional printer board (PRT-MPF-IP), an Eprom Burner board (EPB-MPF-IBP) and several applications delivered on ROMs.

This is something my father bought in early eighties. I would like to suggest a correction to the specs table. Where it says that the on board ROM came with machine code is wrong, it had a full fledged assembler for Z80 processor. Something I used to program my 8085 when I was in university.
