Since the System 3000 servos appear to be made by Futaba, and they specify a standard Futaba "J" connector, my guess is that they would plug right in. Futaba practice is as you state: red=5V, black=common, white=signal. Brett Anthony -----Original (...) (26 years ago, 26-Dec-98, to lugnet.robotics.handyboard)

Then, run IC modem or IC printer depending on which port you are using. It should be configured to boot with (...) (26 years ago, 26-Dec-98, to lugnet.robotics.handyboard)

I assembled the HB board some 2.5 years ago. At that time it seemed to work very well. The hook is that I'm quite strong on the Hardware side and rather anemic with regard to software. In the earlier time I would download it from a Mac 11si-no (...) (26 years ago, 26-Dec-98, to lugnet.robotics.handyboard)

the short answer is that you can't use 3v motors with the handy board. the FAQ states this: (URL) you use the "separate motor power supply" hack, with a 6v battery, you might be able to get 3v motors to work. see (URL) your message you said: (...)

I've had a similar problem, make sure your servo power is fully charged. An undercharged system will sometimes drive all the way one way.
