I'm planning to add a RCX to my CyberMaster, hopefully, this Xmas.
I've done tests with MotorOutput->SensorInput direct connection and it
works, using the Off() and Float() commands to simulate the On/Off state.
Using a simple comms rotine, similar to the VLL code available already in
legOS and NQC source code, or similar to bar-code reader code, one can
devise a bidirectional serial comm with the CyberMaster<->RCX.
Advantages ? PC RF-comms and/or IR-comms with 4 sensors and 4 or even 5
outputs (a pair of each assigned to the comms, so only 4 from the 6 available)
I could save a RCX output, I dunno, by connecting like this:
CyberMaster_Input_1 <= Bumper1...
CyberMaster_Input_2 <= Bumper2...
CyberMaster_Output_A => LeftMoveMotor
CyberMaster_Output_B => RightMoveMotor (or something like that)
CyberMaster_Output_C =>-\
CyberMaster_Input_3 <=--|
RCX_Input_1 <=>---------/
RCX_Input_2 <= LeftEyeAngleSensor
RCX_Input_3 <= RightEyeAngleSensor
RCX_Output_A => LeftEyeAngleMotor
RCX_Output_B => RightEyeAngleMotor
RCX_Output_C => UpDownEyeAngleMotor
So, it's possible to have one pBrick do all the walking, and the other
pBrick obey cmds to move the "eyes" and even, with the possible 3rd output,
control the up/down movement of the eyes.
Or if considered a luxury the Independent Eye movement, the RCX would do
the "arm" controlling instead. ...or both, with a 2nd RCX, because the 1st
could pass along CyberMaster comands through IR messages to any other
possible RCX's we might want to add.
$$$ :)

| (...) That's certainly their choice. I just hope they realize it's sending a mixed message. If you don't know how to recognize an Amazon.com associate ID when you see one, it looks as though TLC is finally (yay) supporting these two wonderful books, (...)
