Do you mean the DSub-19 connector?  Both the drives and the controllers
are electrically identical to the 20-pin header connector style except

Yes, I meant the D connector.

for the provision of both drive select lines and the "pass-through" of

Exactly.  This approach was first used by Apple on the Disk /// drives.

I have tried multiple Apple II units and the whites won't boot on the older ones. I'll have to set them up side by side and try again. It was a while ago. Weather is predicted for about 15 degrees up to freezing the next couple of days and my shop is not heated so I might wait till next week.

Youch!  We're expecting a cold snap, too, but I'm inside.  ;-)
