Apple Computer Inc has wrapped up design of the Macintosh in so many patents that there is not much prospect of anyone coming up with a machine that combines MS-DOS and Mac-DOS environments, but the situation is less clear-cut in Japan, and Sord president Kenma has formed a new company, Proside Ltd, to exploit the fact that the top two machines in Japan, the NEC PC-9801 and the IBM Personal both use Intel compatible chips. Proside has set an 80386-based machine for September launch that will offer full compatibility with both the IBM AT and the PC-9801. The machine, due to be announced formally any day now, will be assembled in Hong Kong where Proside is already assembling a straight 80286- based AT-alike. The new machine will be the first to be both IBM- and NEC-compatible.
