I recently obtained a P3 and I'm and exceedingly happy! Now that I own it Ifeel bad that I wasted a few years trying other solutions that introducednoise and undue complexity into my station. 
Just a few notes and questions because the manual is helpful but I don'tfully understand what I'm reading yet. 
3.    What serial number requires the mod? My serial is 32514.    I need a serial port screw stud - can I buy that from Elecraft whenI purchase a cable + vga card?5.    Is there a quick setup cheat-sheet anyone has for the P3?
Thanks in advance
