200e

I understand Buchla does pulses and gates differently than other mfg's. 
I've never paid to much attention to the differences and have just gone 
about my business.  I now plan on using a simple analog computer with 
my 200e and I want to make sure that I understand the pulse and gate 
differences.  At the very least, I have heard that "Buchla modules 
trigger on the falling edge of a gate."  I'm not sure if that is true.

Can anyone quickly run-down the differences between Buchla and, say, 
most other mfg's.

Thanks in advance!
