My apologies for consuming the net's bandwidth with my prior posting. The Am29000 is in fact endowed with *many* register to register move instructions. Virtually any three operand ALU instruction - including AND, NAND, NOR, OR, and various adds, subtracts, and shifts - allows specification of the third operand as a sign extended 8-bit literal, which may of course be 0, or 0xff as needed. It would, of course, have been handy if somewhere in AMD's documentation this were pointed out explicitly. (The application notes do explain a recommended NOOP equivalent.) Happy holidays to all.
