This model is labelled 'G' for Graphic features. However, for the moment, we know nothing about the technical differences between various 8020 series systems.

Special thanks to **Pierre Vallino** who donates us this computer

The motherboard also included a timer-component that provided for maintenance information on how long the machine had been used.

In 1973, the french mini-computer company **R2E** build the first European mini-computer and called it "**MICRAL**". In 1979, CII-Honeywell-Bull (now Bull), bought this company and presented this Micral 80-22 under their logo.
|
||
|
||
This was a very expensive french computer conceived for the French education market. The price was set ridiculously high since the company knew that the french government would be able to pay such a price !
|
||
|
||
The basic operating system of this machine was **Prologue**, a multitasking, multiuser OS. It was commonly combined with the **BAL** programming language, a mix of BASIC and COBOL with powerful files management commands, made by R2E. Both Prologue and Bal were much more efficient and powerful than CP/M and later MS-DOS but sadly, they virtually never reached beyond the French borders.
