ThreadText: # Replacement power cable for Mindstorms RCX
  
  (Asked by: username_0 on 2012-02-01)
  
  I have an old Mindstorms 1.5 [RCX](http://en.wikipedia.org/wiki/Lego_Mindstorms#RCX).
  
  The plastic on the power cables has degraded, and they short out and don't work well.
  
  [These](http://www.ebay.com.au/itm/ws/eBayISAPI.dll?ViewItem&item=300653416462&ssPageName=ADME%3aB%3aWNASIF%3aAU:1123#ht_949wt_907) look like they would work as replacements, but I'm not exactly sure. I contacted the seller but they didn't respond.
  
  Will these work as replacement RCX power cables?
