ETEQ Microsystems Inc, headquartered in Milpitas, California, has developed the Cougar II and Bengal chip sets to support Intel Corp iAPX-86 clock speeds above 50MHz: a hardware turbo switching feature has been incorporated into the Cougar and Bengal 80386 and 80486 chip sets, and this enables users to mix the type and the order of the DRAMs in the system; also, they support a Weitek Corp 3167/4167 co-processor without any external programmable array logic; engineering samples of the 50MHz chip sets are shipping from ETEQ and production volumes will begin in the first quarter of next year; no prices.
