I've had my thoughts about that - not sure what's under the hood on those,
but Serge used a 4516 on this like the TBK, could this be a random enable,
in that it forces a second counter signal into the first 4516's PRESET
inputs?
Maybe a stretch.

Anyone have a UAP schematic? I'm Serge repairing again and this is one O
don't have.
