This version is much closer to the final than the 11-7 version,
but still has some holdovers from that version such as glowing
shots and the Namco 1984 copyright error. The screen saver
bug has been fixed in this version though. This particular
prototype was autographed by programmer Jim Heuther. This
version still has the crashing bug.
