I believe somebody did a calculation based on the motor driver specs and
some motor current measurements and concluded that two motors was a safe
maximum, possibly under some assumptions that I have forgotten.
I would not be surprised, however, if the RCX contained a circuit designed
to allow any number of motors to be connected without damaging the unit.
You wouldn't get much power out of each motor, though, if this were the
case and there were to many motors connected.

| Thanks Kekoa, I'll have a look at what specs I can find, talk to lego to see if they can offer any add'l info, and perhaps do an experiment or two to see what happens ... I'll post the results for any who might be interested... Jim Kekoa Proudfoot (...) (25 years ago, 3-Jun-99, to lugnet.robotics)
