text: Adding to that, my mother actually owned an MSX as a teenager. There were a lot of edutainment titles, and the MSX it seems was marketed primarily with an educational slant, and a games system and work computer second. Eventually the company (Al-Alamiah) began creating MS-DOS computers, but there''s barely any information I can find about those.

Hi all.
Believe it or not, I became a fan of programming and computers after using one of those around 1985. They where hooked to black $ white CRT TV sets and the programs in MSX Basic recorded in music cassets.
That was in Cuba and were the first computers introduced at high schools along with 8086/8088 Ltels with 256 KB RAM (for the teachers). Damn, I''m so old...

MSX 1 was very popular in Spain. It was sold very well in 84 $ 85, specially Sony and Philips
Most computers were sold in office material shops, nothing related to families, Philips was a really popular brand for TVs and electrical appliances, so many families bought it in the same shop that offered freezers and hair dryers. Sony was popular too and it made a big advertising campaign.
The big problem was the price, a MSX system cost the double that an "grey imported" spectrum, and that was much money for an Spanish family by that time.

It's too bad the standard didn't last. Rather than an official standard for home computers, we ended up with a de-facto standard (the PC).c
Still, MSX are cool machines.
Enrico, I'm willing to bet that there are probably even more unknown MSX system.

Hi Enrico, and every one who loves MSX. Certainly the meaning of "MSX" acronym is secondary, let's use these wonderful machines and enjoy! :D\
And thanks to Old-Computers webmasters for your patience ;). Best Regards.

This is a Sord M5 computer\
http://bernholm.dk/computermuseum/index.php?view=sordm5
There are pictures of games and they look very much like MSX games!
My question now is: Is the Sord an MSX compatible ???
I and other say:
There are some differences, for ex slot format.
Ciao,\

Hi,
I've found this interesting site talking about East countries homecomputers.
http://www.homecomputer.de
Maybe there are unknown MSX clones around the world. For example:

Hi Alberto,
I'm an Italian MSX user. I know that Nishi said that MSX was the acronym of: "Machine and Software Exchageability".\
I don't know if Nishi has said another thing for it. Let me know.\

text: 'Hello, I''ve been an MSX fan for many years and I''ve read several times the origin of "MSX" as "MicroSoft eXtended" acronym but, the same Mr. Nishi who founded the standard in 1983 has declared the real meaning: The first protoype of this machine was called MNX by "Matsushita-Nishi X". This word was registered and then they have to change to MSX for "Matsushita-Sony X". This information is more detailed at Kuniji Ikeda internet news page.'

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 standard was replaced in 1985 by [MSX 2](/museum/msx-2/).
