Made In Japan - Sony.

In the early 80's, there were a lot of home computers. A Japanese company called ASCII corporation (directed by Kay Nishi) decided to create an industry standard for home computers: MSX was born. MSX means Machines with Software eXchangeability. This is the true and only meaning, stop spreading the word about another explanation please.

The new standard was based on an existing computer: The Spectravideo SV 318 which can be considered as a beta version of MSX1 computers. Microsoft designed then MSX1 computers and the first version of the OS: MSX DOS 1 (which looks like early versions of MS-DOS).

Almost every Japanese and Korean computer companies made their own MSX computers (except maybe NEC). Bill Gates was then very confident about the future of the MSX standard.

Spectravideo (one of the MSX companies) made an 80 column card and adapted CP/M for the MSX.

A lot of programs (especially a lot of games from Sega, Konami, Taito, ASCII, etc.) and hardware were developed for this standard. Despite all its qualities, the MSX family didn't have great success in USA. However it was pretty well known in Europe (particularly in the Netherlands and France), in South America (Brazil specifically) and Russia (then the USSR. This is Sony's ealry game home game/pc unit.

The Sony's HitBit 10D was a very basic MSX "1" computer. It is the entry-level system of the Sony MSX range. It has got all the minimum features specified by the MSX 1 specifications: 64 KB RAM, two cartridge slots, 70 keys, etc.

It has no built-in software applications unlike its brother, the HB-11.

It was sold with different colored cases. Red in Japan (only), and black for exportations systems. Like most Sony HB (Hit-Bit) systems, exported systems have a letter at the end of their names indicating the targeted country: D for Germany (Deutchland), F for France, etc..
