I have some older sound cards around that feature these three connectors on 
them,  and in addition have one (perhaps more?) cards that have _just_ those 
interface connectors,  presumably on an ISA board,  though I'd have to dig 
them out of the box to be sure.  In case anybody can use such...

Also around here someplace I have a CDROM drive and interface card that uses 
the old "Philips" (?) interface,  that uses a 16-wire ribbon cable,  if 
there's anyone who might have a use for that.
