This business computer has a monitor and two 5.25" drives built-in. The drives had a door lock so the disk could not be removed while a file was open. The CX-1 uses MCX (Media for Canon X series) as its operating system, which is similar to CP/M.
The character matrix consists of 5x7 dots for normal characters, and of 7x9 for semi-graphic characters. There was a graphic option in Japan (300 x 260), but it never became available in the US.
The Canon BX-3 was the same machine except the CRT was replaced by a Fluorescent Display and a thermal printer.
