Thanks, been there, done that, preparing for it to be happening again sometime soon . . . :-/

Nothing has been de-soldered for this one. I'm taking about the factory wave(?) soldered underside of the SuperIIsi™ MoBo's PDS leaving room the for the Rocket 33/SCSI II Daughtercard topside. [] ]'>

I think I'll practice by doing this hack on one of my spare DuoDock Gemini Cards. If that Hack works, I'll have TWO NuBus Slots!
