  The later revisions add a jumper that lets you select which power supply goes to the Servo connectors (those little sockets in the top left corner). It turns out this is useful if you have a 7.5 volt power supply -- you can directly connect it to the servo, so the regulator doesn't power both the servo and the BS2. (Most servo's will take 7.5 volts, since people started putting together rechargeable 7-cell NI-CAD battery packs).

  What about the difference in the revisions of the Stamp?
  
  FWIW: I think you meant 6-cell packs since each cell would be 1.2 volts.
  
  Thanks for the info on the BOE, though...

  Oops.
  
  Yes, 4 x 1.5 volt Alkalines will get you 6 volts. 5 x 1.2 volt Ni-Cads will get you -- hmm, 6 volts.
  But then, 5 x 1.5 volt Alkalines will get you 7.5 volts. I knew it was in there somewhere.

  The revision F BASIC Stamp is our current BS2-IC model.

  40 bucks for a returned BOE and Chip? Well, since a new set is over $100, and separately the chip is $50.00, I suppose this isn't too bad. Not as good as $20.00, which is where they started. Oh, well, that's a dutch auction for ya.

  Allan,
  
  We were a bit hard on ourselves.
  
  Actually, they were not "used" returns in the form of previously handled and programmed. Rather, perhaps a package had been opened but otherwise things were brand new. For example, if we sell a kit at Fry's and somebody opens it up to steal the Stamp module, they return the whole thing and we sell the BOE part on eBay. It would have been more accurate to say "new, but previously opened". But the "refurbished" description gives us latitude by ensuring customer expectations are exceeded. When they get a new Stamp and BOE in a bag they're really happy considering they expected something refurbished - whatever that means. Now you know a big marketing trick.
  
  Our internal "system" - the way we receive products in stock, ship them out, kit them, etc. doesn't allow for us to make returned stuff new again (not to mention the company philosophy). So, our forum users will really benefit from these eBay deals because we'll always let you know first. Knowing what I know from the inside, this refurbished stuff on eBay is a great way to buy Parallax! Chances are it's really a new product.
