Not sure why, but at some stage of this machine's life it was converted to a Pong. Admittedly Pong was a much better game. The owner emailed me to advise that as conversions go, this is a very professional job, the new control panel fits perfectly and the internal parts are all proper Pong parts.

Perhaps an arcade owner felt the need to turn the lousy gameplay of Computer Space into something more profitable. This was definitely converted and not an empty cabinet Nutting Associates released as a Pong style game. Nutting never altered any of their Computer Spaces.

This unit also sold again on eBay for $750 on January 3rd, 2006.

UPDATE: This machine has been somewhat restored to a proper Computer Space game again and was shown in early 2008 in Melbourne's Australian Centre for the Moving Image (ACMI) exhibit of Game On. IGN did a story on the exhibit which can be read here. Click on the thumbnails at the bottom of this page to see a larger version of the restored unit.
