I don't think they are willing to change the main processor (and all the software involved) just to accomplish this... unless there are another versions of the H8 that have more inputs/outputs (?)

RCX is HUGE? You should see a CyberMaster unit... that's HUGE!

You also should weight a CyberMaster unit. That's HEAVY!
The two internal motors are the main reason for such size and weight.

Something between a CyberMaster and a RCX would be ideal.
The radio link from the CyberMaster and the memory and software from the RCX.
Also, the two internal motors from the CyberMaster should be made external. That way we would have 2 external hi-torque motors with rotation sensors integrated AND without the need for connecting them to the inputs!
Yes, the CyberMaster motors only have two connections.
By the way, how can they drive a motor and receive feedback from it 50 times per rotation using only two wires ??? (have I seen this wrong?)
