Subject: Definitive Opcode List - (nf) One collection of new opcodes was one that I collected for the Michigan Technic (at Univ. of Michigan) several years ago (which is probably where the person from U of M copied it from...) "The Technic Guide to Assembler Language" appeared in two parts and was the "best" of some 250 opcodes that I invented, got from friends, or found in various locations (from the library to East Engineering Bldg bathrooms) at the school. The list that follows contains most of them, and a few more that people here (at Intermetrics) have added to the list. Enjoy. Jeff Diewald Intermetrics, Inc.
