The Chuff-n-Puff board is different than the Turbo-Smoke, at least it sure looks like it. The Turbo-Smoke is one I posted, it's documenting the actual smoke unit, but it doesn't mention the separate Chuff-n-Puff board.
I have three of these in my parts box, they're labeled Smoke Unit Circuitry, I believe they were to make a dumb smoke unit smart.
Then there's this TAS combo, not sure what this is...
