PC Magazine, July 1990, pages 425-426, tells how to separate 80286s, 80386s, 80486s, and lesser chips. It mentions a March 13 column that told how to detect a math coprocessor, and promises a future column to identify math coprocessor types. It glosses over the method of separating the lesser chips: 8088s, 8086s, 80186s, and NEC V20s and V30s. Apparently you know how to do this (or at least some of it); could you share the method or a reference? ---------------------------------------------------------------------- Dave Dodson dodson@convex.COM Convex Computer Corporation Richardson, Texas (214) 497-4234
