Unreleased ColecoVision Game for Sale

Digital Press is holding a private auction for Power Grabber, a one-of-a-kind prototype of an unreleased game for the ColecoVision.
Power Grabber was developed by Sydney Development, a long-defunct development house perhaps best known for developing BC’s Quest for Tires for Sierra. The game was made in response to the Canadian Atomic Energy Commission’s need to entertain the kiddies while the adults were given tours of their facilities.
It was long-rumored that Power Grabber was distributed to the facilities, but this prototype board is the only copy of the game known to have turned up thus far.
The game consists of two EPROMs on a bare circuit board. The starting bid is $940, a sum I’d be hypocritical to challenge, and is being auctioned privately on this thread of the Digital Press Forums.
