The last card-cage based repeater I did (a Micor, which uses a card cage like a MSR) I did a bit differently.
The squelch gate card mod (the one with the DB connector and a 3-pole switch) basically turns it into a two-mode card - mode one is a paddle board that connects a outside controller, mode two is a squelch gate card. Rather than mod a squelch gate card I took a timeout timer card and stripped it. A second one provided some more pins for the connectors. On the front panel I added the DB connector for connecting an outboard controller. I added a piece of perfboard on standoffs for the LED drivers, etc. This way I can plug in an unmodified squelch gate card into its slot for use as a kerchunk box, or plug in the paddle board for all-the- bells and whistles controller. Good working squelch gate cards are too hard to come by to take a chance on messing one up.
