Even though we know almost nothing about this Micral series, it was probably one of the first of the Micral 80xx series to be designed by R2E.

Its hardware design was the same as the first Micral models, a bus card mounted along with several daughter boards. In the following models, i.e. the 8020 series, R2E had used a single board with expansion slots.

The Micral 8030 and 8031 belonged to the same family. At least 4 versions of 8031 were launched, from A to D, but we don't know the technical distinctions between each version.
