A little update... instead of working on my (4, sigh) other projects, I spent the day replacing the 4-way on this cabinet to an 8-way LS-56 w/ octagonal gate, which seems to work well enough for Pac Man, etc., and opens my game list to some 8-way classics. Took off a bunch of games we never played (Pooyan, DK II hack, Pop Flamer, Guzzler, Roc & Rope, etc.) and added several (Gaplus, Gyruss, Time Pilot, Q*Bert, Exerion, Juno First, Bomb Jack, Kangaroo, Xevious). Easy part was drilling mounting holes for the LS-56 on the Ms. Pac stick mounting plate (plenty of room). Hard part was remembering how MALA and InstantSheller were set up.
Happy to say the cab is holding up well after 2+ years!
