Keyboard layout was designed for company keyboarding.\
|
|
Numeric keypad included '0', '00', and '000' keys. It will be replaced with an arrow keypad in the Bull version.

The motherboard is quite the same as Bull 80/20 series.\
|
|
Notice the switching power supply **(1)** while the Bull one uses a transformer, and the metallic support **(2)** for expansion cards.

This computer was basically the same as the [Bull 80/22](/museum/bull-micral-80-22/). However, the machine seems to have been designed by the team of R2E after the company was bought by Bull in 1978.
|
|
|
|
It was first designed as an opened business system intended to be integrated into company networks. However, some time later, Bull got a significant part of the French educational market, so the R2E system was adapted to meet the Department of Education requirements and became the Bull 80/22.
