I kept a number of the old VEX 75Mhz transmitters, crystal receivers and their 6 motor signal splitter. A hand full of PWM motors (or PWM controllers and motors) and I'm good to go.

I've also used the DFRobot Arduino/power base (Romeo). Use their Xbee controller and you are good to go

I know the OP wanted older, unloved FRC controls, but unless they are building something complicated, the cRio and support stuff is overkill.
