We purchased some of these to try. It's a nice holder though a bit pricey
perhaps at about $11 each. It has a polarity-reversing switch meant to drive
the 9V motors directly. Eliminating this switch would have the advantage of
saving 2 diode drops in the main power supply voltage.
BTW, does the RIS2.0 RCX have a power input jack?
