      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.
