The triggering is fairly intelligent.  It matches on any pattern on any
subset of the inputs, and can also count how many times it has been through
a loop and only start on the 47th time through and things like that.

It has somewhere around 40 channels, and can record up to 1024 states.
That's enough to watch every interesting signal for a couple of character
lines worth of time.  The only problem is that I have to type the results
manually into a computer - it's got an IEE488 interface, and I have nothing
that will talk to that.
