An external trigger output would dramatically improve the Logic devices. I often had to find hardware failures caused by power and signal integrity issues. MSOs helped but before those the logic analyzer trigger capabilities were often needed. MSOs are often not very good analyzers.
this could be performed using 3 party HW like a COM Port, without HW modification for low cost triggering on previous HW
This is an excellent idea. Essentially, it would allow you to use an affordable oscilloscope as an MSO. MSO's are typically much more expensive than a standard O-scope. With this feature, a Logic would more than pay for itself when coupled with an Oscilloscope. In my opinion, this is would make Logics more attractive than the more expensive LogicStudio.
Could also be used to reset the device under test.
This would also allow Logics to be interconnected and share a timebase.
