      This is the main unit without its monitor which plugs on top of the unit through a special connector. When the monitor is connected it can not be moved in any direction :-(

      This is the monitor connector on the top of the main unit. It's a flat connector which plugs into the slot of the monitor itself.

      We can spot here the slot which fits with the connector found on the top of the main case.

      My father brought me one around 1987... It came with a bootable floppy with an operating system similar to DOS (the boot loader was contained into a file called AXEL.SYS). Commands such as DIR, COPY,REN worked fine.

      I also had Microsoft Basic (MBASIC) on the boot disk.

    text: I just wanted to say that the Axel AX-20 looks very familiar to me. When I was younger, In the year 90 or so, I was learning to code in Turbo Pascal on a clone of this system. It was made by MATRA and was called MAX-20 (M was for Matra I guess while AX-20 was the name of the system).

This french mono-bloc system had no great success. It was however a nice designed system with its 8 function keys mounted directly onto the monitor (like with some Hewlett-Packard systems). The idea was interesting, because the function of each key was dynamicaly displayed right above it, but it becomes tiring to have to lift an arm to reach these keys...

The AXEL-20 can display 640 x 416 pixels with 8 different level of brightness. The system has it own character set (128 ASCII characters, upper and lower case). The user character generator is only optional. In fact many features are optional; real-time clock, disk-drive, expansion bus, V24 card, modem, graphic card...

The AXEL-20 is not IBM PC compatible at all. It can only read IBM disks with a special software tool.

The OS and languages available were MS-DOS, CP/M, Fortran, Basic, Pascal and Cobol. Software amng others: Dbase II, Multipla, Wordstar.

The AX-20 was marketed as the [MAX-20](/museum/matra-max-20/), under the Matra brand ("M" for Matra ?).\
Two years later, an enhanced model was marketed: the [AX-25](/museum/axel-ax-25/).
