About a minute in, he talks about the work he did at Western Technologies, programming VCS/2600 Raft Rider and Qbert. He also mentions WT getting the contract to make home versions of a Mylstar arcade game that wasn't released called Qbert Circus. I'm not sure if he's confused and was talking about Q*bert's Qubes (which a VCS version was released) or possibly Circus Charlie (which a VCS version was planned but never released).
