A kindly reader has sent us two URLs possibly worth reading if you like the G4 PowerPC 450MHz microprocessor. The addresses are this and that. But go back a bit further just to here and you'll find some stuff about Sony's Emotion, AMD's K7, Intel Coppermine, PA-RISC 8500, Dirk Meyer's RM presentation and gawd knows what else. Go back just to the IP number and you'll find the source of this stuff, which is the Simulation Optimization Systems Research Laboratory at McMaster University in Ontario, it claims. The files all arrived there on the 14th of June last. All letters to IBM, err sorry Motorola, err sorry Intel, err sorry AMD, err sorry Sony. ®
