Re: [vcf-midatlantic] Schematic work needed
There's one for $40/free shipping right now:
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 thing: https://www.bricklink.com/v2/catalog/catalogitem.page?P=70455#T=C&C=11.
The receptacles that the various Lego things plug into, in the control box? Those are a little formed contact with the housing of the control box making up the connector shell, from what I remember. You could probably cob something together that'd work, but you can't just go buy that connector, as far as I know.
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?

I figured it out. I was going by the set #, not the part #. Sets contain multiple parts, of course. The part number is 70288 for the 1986 version and 70455 for the 1987 version. What's the difference between the versions? I have no idea.
There are minor differences in the circuit boards, apparently the biggest outward difference is that the LEDs on one are regular domed 5mm LEDs, and the other uses LEDs that are flat with the front of the enclosure.
