Dean,
    Your motor multiplexer is cool, but not really what I'm after.   What I
need is a way to have a single output drive several motors in the same
direction at the same time (IE Hook them all up in parallel.)  After reading
some of the posts here and thinking about the fact that the RCX only uses
AA's it's clear that I don't want to run 4 motors off of each of the 3
outputs.  Even if it didn't hurt the RCX, the motors wouldn't get much juice
: (  What I think I really need is a current amplifier that can switch fast
enough that I don't lose the PWM signals.  Is there such an animal ?
                                            Thanks,
                                            Xanthra47
