Computer
The CF-3300 is a home computer produced by the Japanese corporation Matsushita Denki and released in early summer 1985 in Japan.
It has the same look as the CF-3000 as it consists out of a single case with a separate keyboard with numeric keypad. Like its brother, this model is available in silver color.
However, it has a built-in disk drive and a special connector allows to add an external second disk drive. It was also the first computer to ship with MSX-DOS 1.
The MSX1 product line from National was called "King-Kong".
