Hi. I have some layouts for a Logic Based Module and a Comparator module.

The LogicOgic has a few AND/OR gates, a couple of FlipFlops and an Inverter/Buffer. There is a Daughterboard for a Quad SquareWave Oscillator bank.

LogicOgic

The Comparator Module is based on an LM239 Quad Comparator. You would probably be fine using a 339. I haven't tried though.
It has a variable threshold for each comparator. It has Gate and Trigger outs.

LM239 Quad Comparator

Both of them can be powered by 12V even though I have only used them with 15V.

Be careful! They deliver 11V-13V at the outs. If that freaks you out then tack on a voltage divider.

Good Luck thumb up
