The Chuff-Generator wouldn't work as it for the tach generator for TAS. OTOH, if there was a significant interest, I could reprogram it so that it would generate an output for every tach stripe, which is all the TAS board does. I have thought about this if it ever came to not being able to get the EOB boards.
Another option is to simply layout the TAS tach generator and build one, it's a simple circuit.
