SN 10023 is a recently restored Computer Space now owned by the people formerly behind the Classic Gaming Expo as well as the National Video Game Museum.
According to the people who contacted me this unit was in dire need of a complete overhaul and restoration and, as seen in the pictures below, a lot of work went into returning this machine to its former glory and the work was carried out by Scott who also owns SN 10269.
Visitors to the Museum can check out this unit themselves in person.
