Rear Panel Parts from an Older Industrial PC. Includes 5 DB9 com ports, one DB25 parallel, ethernet, and DIN power connector. If you occasionally work with older PC motherboards or even modern industrial motherboards these can come in handy. I imagine the com ports use a standard convention for pin order, but I can't guarantee compatibility with your application.
I have a number of these, photos are representative. Please note the power switch wires are cut short.
