All those "No's above just mean it's a lot easier than you'd thought, buddy! :approve:

Some new ones: next revision involves no SuperMac Card, no jumper wires and no EuroDin wall hacking at all. ;D

All I need from you would be the dimensions requested above a/o a couple of pics of your great RCPII/IIsi-in-SE/30 hack roughly showing the relationships of the Pivot card with the SE/30's PSU etc.

Back in? :lol:

edit: determination that the remaining control lines are compatible remains paramount. That's the go-no go for prototyping.
