the cybermaster are constructed in such a way that I can apply a voltage to the
input instead of just a resistor. It might have to be through a 1:1 coil in
order to galvanic (??) seperate the input from the sensor. Can anyone verify
this?

Also does anyone know the opcode for resetting the tacho counter?

Thanks to Michael Barrett Andersen who knew that the opcode was 0x11 I now have
control over the tacho counters as well:

0xFE 0x00 0x00 0xFF   0x11 0xEE   0x01 0xFE   0x12 0xED
|  Header           |  opcode   |  motorID  | Checksum |

MotorID is: 0x01 0xFE or 0x02 0xFD or 0x03 0xFC

Go see http://graphics.stanford.edu/~kekoa/rcx/index.html
and http://members.home.nl/b.vandam/robots/crack.html
for details on opcodes and how to calculate checksum

Now that's sorted I just need to figure out if it's possible to apply a voltage
to the inputs.
