At Pioneer we've never believed in following the crowd. We prefer them to be one step behind us. And with our innovative reputation in Hi-Fi and In-Car . Entertainment, people tend to demand rather special things from us. Our new PX-7 home computer is just that. It has all he benefits you'd expect from a standard MSX home computer, but with a few added talents. No other home computer enables you to create your own art and animation like the PX-7. Up to 16 different colours are available and by using the optional PX-TB7 graphics tablet you can create illus trations , shapes and various backgrounds. Then store up to eight of thse shapes with their respective animation programmes in the computer memory.

a video or LaserDisc* player to superimpose your graphics, creations or titles onto a moving video picture. The PX-7 can also produce stereo sound with three different voice patterns over eight octaves and superimpose them over other sound sources.

Moving Pictures. Use the PX-7 in conjunction with

'

SD-26 component television and LD-700 LaserDisc* player, the PX7. has the added versatility of being able to understand and control the complete system. So if you're looking for a home computer that's versatile, talented and one step ahead of the .crowd, remember there's only one. The Pioneer PX-7. Phone 01-200 0200 for your nearest PX-7 dealer.

eehe coming months may well determine the future of the British and the place of MSX within it. In spite of widespread attempts to imbue home computers with a more 'serious' image, games continue to dominate the software scene, and Christmas continues to dominate the thoughts of manufacturers who rely on autumn nights and seasonal spending sprees for the bulk of their sales. That, at least, is the Western tradition . The Japanese manufacturers of MSX computers have shown far less concern, not only with seasons but with boosting sales in the UK in general. The reason for this might seem increasingly clear . The recent announcement of an initial order of 4000 machines destined for the Soviet educational market, and the likely promise of bigger orders from the same source to follow (see Pulse), indicate that the big Japanese companies are more interested in the wide open spaces of the world market than in penetrating an already crowded British scene. With a user base of roughly 1 million machines in Japan, and over 200,000 in Europe, the MSX makers have so far had little to worry about. They no doubt believe that as MSX establishes itself as a world standard, and as sales for the major British makes like Sinclair, Acorn and Commodore lose their momentum, Britain will eventually come to MSX as the mountain comes to Mohammed. MSX observers have always been divided into two camps. There are those who say that MSX is bound to succeed because the Japanese never fail at anything. And there are those who say that this is the one time when t e Japanese have got it wrong. According to the pessimists, caution will be the undoing of the MSX manufacturers. By the time they make up their minds to actively promote and sell their wares, British add-on makers and software houses will have given up hope in MSX, other micros such as the Amstrad will be the new stars, and there will be no market to sell to. The alternative view is that, still as shrewd as ever, the Japanese are well aware that British sals are important - not for so much for bulk as for prestige. If MSX is to be launched in the US - and the most likely estimate is that it will be in the shape of MSX Plus some time next year - it will do it no harm to arrive already equipped with a good British reputation. Therefore, at least some of the MSX manufacturers, if not the group as a whole, will be making strenuous efforts to grab a share of the British market this autumn, before it is too late. So whichever camp you are in, now is the time to place your bets.
