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.)
