Amen!

No reason why it couldn't also have pass-through card edge fingers on the
opposite edge extending the port; that's how we connected to the IEEE port
without the expensive hard-to-find connectors while still leaving a place to
connect the standard cable connecting other drives/printers etc., and it
would certainly keep costs down.

But Jim does have that inventory of connectors to unload... ;-)
