Like the [MAX 20](/museum/matra-max-20/), the MAX 90 was derived from the [AX 25](/museum/axel-ax-25/), a computer designed by Axel, a small and innovative French company.

It was an almost PC-compatible system including some rare features at that time: 8 MHz 8088 processor, high resolution capability, and especially one or two 5.25" floppy disk drives of 2.7 MB capacity each. To our knowledge, it's the highest capacity ever seen for a 5.25" floppy drive unit.

A few thousand systems were sold to the French civil services, but this computer didn't become a success with private companies.
