[comp.sys.ibm.pc.hardware] Vga connector

   What is the top card edge connector on VGA cards for exactly?
   I've seen reference to it as the VGA Feature connecter and
   the VGA Passthrough connecter.

   Can I use it to add some experimental circuits to my VGA cards?
   I've noticed that some graphics coprocessor cards don't have
   an output for the monitor but a connection for the
   Passthrough connector.

    Where can I get a description and specifications for this
    connector?

	Someone once told me that the top card edge connector could be used
for such popular peripherals as light-pens.
