How to check if Prop 1 is bad.

[youngti]

Hi all, I have this prop (https://www.efx-tek.com/php/smf/index.php?topic=804.msg4450#msg4450) that has been working for years with no issue.  How ever today it does not function.  I can hear the speakers come on but no trigger or programs seems to run.  Is there a way to check the Prop 1 to see if its okay?  The prop has three boards, Scary Terry servo driver, Cowlacious audio and the Prop 1.  I have dups of the other two so i can swap those out to see if they are the issues.  But i have no Prop 1 to test.  thanks as always for your help.

Okay i think the Prop 1 is okay.  I was able to plug in the USB BS1 and got lights on the 1 and 2 switch position and the Basic stamp software sees the Prop 1.
