Thanks to the demands of technical and scientific users, personal computers and workstations are going through a phenomenal evolution in terms of performance. Third‐party vendors are leading the way in developing accelerators in the shape of coprocessors that push the speeds of commercially available CPUs into the range of more specialized and expensive workstations and minicomputers. YARC Systems, of Agoura Hills, CA, recently announced the availability of a new NuBus board, utilizing a Am29000 RISC chip operating at 67MHz. This product, appropriately called MacRageous, will produce a performance level on a Macintosh of 27 million instructions per second (MIPS). Tests at the University of Virginia have indicated that MacRageous outperforms IBM's System 6000 SuperStation, one of the fastest workstations currently on the market. Of course, a product such as MacRageous will require the development of customized applications to take full advantage of its horsepower. In anticipation, YARC will make available a full line of compilers and debuggers. MacRageous will be available for prices starting around $2,000.
