LB 102 programming for PEN trigger

The first LB102 produces different combinations out of the ten super-clusters low and ten super-cluster high signals. The first is the pi-beta trigger high and low, which requires two opposite hits. The pienu trigger high and low require just one hit.

The labels on the inputs and outputs are in the form HnPm, where n is the header number (1...4 from top to down) and m is the pin number (1..16, as labeled on the unit).

Here is the toplevel schematic:

It contains the back-to-back logic:

Here are the shapers:

The additional buffers at the output of the shapers are for signal delay.
