Happ coin doors

Suzo-Happ, never content to leave well enough alone, produces their own doors as well as having bought the previous. Pinball collectors will see these on new Stern titles, starting sometime after 2003. Jersey Jack Pinball and Spooky Pinball also seem to have used these doors in non-DBV versions.

Spooky and JJP tend to use games without the DBV setup (at least on their flyers) since home use doesn’t benefit from the extra DBV bits.

There are AT LEAST two types of Happ DBV (dollar bill validator) doors that appear on pinball machines, one with a gusset and one without. The transition was around 2014/2015. The newer door has a larger space for the newfangled upstacker, but removes the gusset. This eventually caused Stern to stop putting a sticker in that gusset, but on games made with both door variants, they added the sticker wherever.

There appears to be a third type of door that I don’t have an example of with just one hole for an upstacker, but lacking the upper hole. IPDB has an example. Happ’s web site tends to reflect current inventory, not historical parts, but the relevant section is here.

I prefer the older DBV door, because there’s a mount point for a slam tilt switch, which the Stern harness supports. But I’m not too worried about installing dollar bill validators in the games at my house. Marco Specialties has a kit for this switch. I think the documentation is wrong because there are a lot of games that this won’t fit.

Stern’s Star Trek was made with both of these doors. Unfortunately, that kit doesn’t work in this game (regardless of the documentation) because the mount point has been removed. Old Midway doors used a different approach that will work here: This bracket mounts the slam switch to the lock. In this case, the right thing to do is to use that bracket and make your own “kit” for the switch, since it’s just a couple pins and a Molex connector. (In this case I mix-and-matched parts since I had the kit from Marco.) A little finesse made this fit.
