No. Flip a DIP-switch and it's there. There is a few connectors on the
motherboard and that hooks up to the connector panel. I've checked and
I've got the driving chips on my various boards.

It is indeed the hint I am giving. If you use the fast-port with a
suitable back-end, you can do a lot of stuff that you would otherwise
not expect from that machine.
You can do three-clock comparisons in continuous mode if you like.

You can control that very easily with the trigger rate. The time-tagging
rate is actually rather high on these beasts, but memory storage is what
reduces it's speed and depth.
Cheers,
