Note:  I had one item damaged during shipping (two long plastic marquee holders).  HappControls easily replaced them for free with a phone call; I didn't even have to ship them back!

Note:  Cutting a groove for t-molding requires a wood router and a t-molding bit (picture).  That bit assembly is sold in two different pieces.  The round yellow cutter and the ball-bearing steel shaft are sold separately.  There's a bolt hidden underneath which lets you take the assembly apart.  It took me two months to find this bit.  The Woodworkers Warehouse had them, but they went out of business in December of 2003.  Don't expect to find these at Home Depot; only specialty wood shops carry these bits.  Home Depot does carry other router bits, but not this one.  It's a carbide tipped bit.

I-Pac 4:  Used to wire joysticks, buttons, and the coin door (the switched that the quarters trip when they fly by use a very similar switch that the buttons/joysticks use, so wiring them is just as easy as everything else).

Opti-PAC:  Used to wire the trackballs and rotary/spinner controllers.  It also is wired up to four different buttons (two of the left trackball, two for the right trackball).  This treats your trackballs and rotary controllers just like mice (although the rotary controllers only move "left-right" or "up-down" depending on how you wire them).

Note:  My original I-PAC 4 was faulty.  Apparently there was a bad batch of them made during late 2002/early 2003.  I happened to get one of those cards.  The solder on some of the connections wasn't applied correctly.  After I wired it up the Player 1 and 2 controls worked fine, but the Player 3 and Player 4 controls didn't work (or would work for a few minutes and then cut out).  I wrote Andy at Ultimarc about this seven months after I had purchased the cards (I ordered the cards before I finished the control panel), and he sent me a replacement I-PAC 4 for free.  Top guy!  Now everything works perfectly.  Thanks Andy!
