COMPUTER NETWORKING IN JAPAN 1985 - ONWARDS AND HOW BILL GATES' (MICROSOFT) CREATED THE FAR EAST & PACIFIC MSX STANDARD Robert M.

In the early 1980's, Bill Gates' foresight & precognition again came to the fore and INTRODUCTION: Microsoft, called ASCII Microsoft Ltd. in Japan, developed the MSX operating system Gridley, here is your trivia question of for microcomputers that utilize the Zilog the week. Why is Apple to microcomputer Z-80A microprocesor (or its licensed similar to Microsoft to software? counterparts manufactured in Japan). The idea here was an extremely sound one; i.e., Gotcha coach. They are both the biggest in any microcomputer using the licensed MSX their respective fields. operating system would have complete software program compatibily with any other Not really, Gridley. IBM's dividends microcomputer using the licensed MSX exceed Apple's 2 billion dollar annual operating system. Beyond software sales. ; hrthermore, there are a number of compatibility, a further goal was to have software houses that are as large or larger completely interchangeable peripherals. than Microsoft% $200 million annual sales. Try again, Gridley. Think back to the 1975 In addition to the usual line printer, - 1976 era of yesteryear tall masked man. light pen, etc., peripherals, they also include stereo sound, video disk, and video Aha, you gave me a clue, coach. Both firms cassette, plus optional growth capability were started by rather young computer buffs via the MSX DOS (disk operating system) to working in garages, dormitory rooms, or the use the new 360K byte (formatted) 3 l/2" attic. floppy disks now being manufactured in Japan. Microsoft provides the MSX disk Right you are, Gridley. Steve Wozniak and operating system on a chip which is built Steve Jobs at Apple, and Bill Gates and into the floppy disk drive adaptor. Paul Allen at Microsoft were the leading perpetrators - founders, of these two out- FUNDAMENTAL MSX OPERATING SYSTEM SPECS: standing firms.

The MSX spec is Microsoft's achievements are really too aimed at the universal "home computer" numerous to mention, but two items market. Notice we did not say "personal particularly standout. The first and most computer" market as there is a substantial obvious is MS DOS, the fundamental PC DOS difference between the two. It is obvious disk operating system for the IBM PC.

Analog Red Green on with the packet story line which is what Blue (RGB) output is another option. this discussion is supposed to be about. It is worth noting that the majority of MSX Sorry Gridley, I got carried away by all micros offer RAM expansion to 64K bytes, so these fascinating facts and figures. undoubtedly virtually all of them utilize bank memory switching between ROM and RAM.

You should also note that virtually none of the MSX micros include or Yes indeed Gridley, especially when one offer the RS-232 serial interface that the considers that the first Japanese AMSAT hardware variety of packet radio buff is so bird with AX.25 packet capability is going fond of using. to be launched in 1986, plus a number of forward thinking Japanese amateurs are Another fascinating aspect of the MSX already planning a number of AX.25 protocol specification is what ASCII Microsoft packet repeaters for installation beginning Ltd.% Mr. Kazuhiko Nishi terms the "MSX the summer of 1985.
