Hmm. That's weird, I knew it as part #9750, so I searched for that term. 
Did not know to search for #70455, which apparently is the same exact

Oh, didn't know that.

I do know that 3mm mini-banana plugs fit perfectly into those holes. So 
the matching 3mm receptacles would do fine rather than using the Lego part.

Speaking of which: I take back what I said earlier about "100% perfect". 
I meant 100% functional, not 100% in appearance. It could be powered by 
a Raspberry Pi for all I care. I just want to give people a way to run 
the vintage software (Lego Logo; BASIC; etc.) on their Apple II or IBM 
PC and connect it to the period 1980s Lego motors/sensors. Is there a 
easier/modern way to create the middleware hardware?
