Hi
 I don't need the fancy differences in the currents. One
side drives a higher current than the other. The actual
circuit would work fine with a little simple glue logic
and a pair of '240 TTL's.
 It just has to drive the bus on the SYM and a little
bit of circuit on the on board bus.
 I'm just a little lazy at getting around to actually
doing it. The right chip would peak my interest.
