This MSX system has only 16 KB and one cartridge slot, nearly the minimum required by the MSX standard. It is quite similar to the Casio PV-7, but doubles the RAM, which is the minimum if you want to run a minimum of MSX software.
Hopefully an expansion unit (KB-10) was available and added two catridge slots and more memory to the MX-10.
There are big arrow keys on the right hand side of the keyboard arranged in circle. The whole pad is called "Joypad 1" and emulates a joystick inserted in port #1. The two big blue keys "TR1" and "TR2" on the left hand side of the keyboard are the two fire buttons! Notice that there are also "classic" arrow keys at the top of the keyboard...
The keyboad is really poor, the rubber keys are too small to do anything with them. Casio almost marketed the MX-10 as a cheap MSX video game system.
The MX-101 is quite similar, but is wireless. It has a wireless video signal transfer - there are two antennas included in the box.
