I found the write ups on the mods (duh - helps to read the
caption)

I REALLY like the auto trigger option and will pop this in one of
my two 140's right now. I did something very simular to my
Blacet EG, but also had the room on the faceplate to create not
only and end of cycle pulse, but the inverse, a 'cycle active' gate,
which is really useful as it allows for an enabling signal for
gating only when a certain envelope is firing.

In any event, gotta go - I'm going to slap this mod in right now.
