Nintendo Co Ltd has sprung a surprise by saying that it will unveil a next-generation 32-bit games machine featuring virtual reality software this November. Its current machines are 16-bit, and while the company has said that it is developing a 64-bit machine using the MIPS Technologies Inc R-series RISC for 1995, it has hitherto made no mention of a 32-bit one. No word on what chip is being used but presumably it is a 32-bit version of the MIPS chip. Nintendo would say only that the new product is a virtual reality game that does not require players to wear special eyeglasses.
