+I got some of the 5747467 parts (the -1, -2, -4 etc indicate the quality of the gold plating). Sadly, they don't have any boardlocks, so the user will need to attach them to the PCB with M3 (or 4-40?) machine screws and nuts. Not ideal!
+
 Are there any other black plastic DE9 male sockets? Try Harting, Kycon, Amphenol, etc.
 
+A surplus store in Nebraska has some super cheap - 65 cents each!

 Bought some from Alibaba. Found a PDF online from Kycon. I think I also found a second vendor and the diagrams matched to within 0.1mm.

+I also bought the Kycon one from Mouser and it looks good (although black/black not purple/green).

 # Case
 
 I'm using a Hammond 1598C, with Parallel Port and Serial Port on ribbons.
 
+I bought one NOS, and the screws were rusty. I bought a new one from Mouser in Beige and the finish on the parts where they meet in the middle wasn't great.
