(...) First, put batteries in it and turn it on. It'll beep 'ok'. Then attach a technic 9v motor to port A with a wire and press Run. If the motor spins, the brick has basic sanity, and it's worth your time and money to get a IR tower to program it (...) (19 years ago, 7-Apr-06, to lugnet.robotics.rcx, FTX)

Hello all. I know almost nothing about LEGO robotics, but my mom picked up an RCX 1.0 brick at a yard sale. I just have the brick - no accessories, no software.

Beware of the fact that the outputs on the RCX output PWM. You will probably want rectification, and need smoothing to get a nice constant voltage (some regulator in the LM series) to power the board. Anyway - it sounds like a really good idea - I (...)

I’ve just started a little project of building an interface between a RCX and a Bluetooth.
