Off the top of my head: AClink (audio), i2s (audio), SSI/SSP (synchonous serial), Firewire, rs232, CAN, FibreChannel, ISA, PS2, ADB (apple desktop bus) and probably a bunch of others I've missed. There's also a bunch of all-but extinct system architectures with interesting bus-level features (MCA, NuBus, etc.) Paul
