On March 30, High Level Hardware Ltd, the Oxford Unix systems manufacturer, will broaden out its line of Unix processors with a top-end line built around the Fairchild Clipper chip set. High Level is not saying anything about the new machines beyond the fact that they will come in above the existing Orion bit-slice machine and that it will definitely not be discontinuing the latter – you can’t micro-code the Clipper, comments the company. Users of the Orion will also be able to upgrade to the new Clipper-based processor. The Clipper is a three chip set comprising the arithmetic logic unit and two large cache memories and controllers.
