(...) Uhhhh..... You are worthy. I can create a full adder (A+B+Carry in) in three pistons, 17 switches (7+7+3) and no rubber bands. You win on switch count. I win on band count. Rereading my post I can see how I led you astray. Mark is worthy.... (...) (21 years ago, 19-Jun-03, to lugnet.technic)

(...) Bizarre! The bids are up to $172.50 at the time that I'm writing this! This is a current product that pretty much anyone anywhere should be able to order from LEGO for a lot less than that. Why on earth would the bidding go that high? (btw, (...) (21 years ago, 19-Jun-03, to lugnet.technic, lugnet.market.shopping, lugnet.market.auction)
