I did some image-flippin' after I snagged the SE/30 MoBo piccie, threw it onto HP_Mini's upstairs 32" LCD "Monitor" to examine the Keying on the /30's PDS Connector as compared to that of my IIsi NuBus Adapter's Connector. I came to several conclusions:

(1) MacCharlie is outta' the picture . . . :-/

(2) the two outside rows of connections would wind up flipped . . . ::)

(3) . . . they're scarce as hen's teeth and don't fit with the /30 historically anyway so . . . :I

(4) . . . fabbin' one outta clear plexi wouldn't SE/30 Correct anyhoot! :p

(5) . . . and it's not a problem! 8)

(6) The 'ole ZFP_Sub-BasementExpansionBay™ ploy is the answer to a NuBus friendly SE/30 Hack! [:D] ]'>

You've gotta flip this piccie 90 degrees leftwise to have it line up with the Gamba Diagrams, but it posts better as is.

The VST ThinPack background (Auxiliary PowerBook Battery) was thrown in to show off my PB100_Sub-BasementExpansionBay™ as well as to make the background clutter of my Bedroom TeakHackStation™ disappear! [;)] ]'>

This pic details the edge of the connector that'll make this hack a (decent solderer's) snap!

IIRC, they're called Machine Pin Sockets and they're upside down in the pic. The "Socket" is a perfectly round funnel shape that sticks onto the Solder Side of an SE/30 or IIsi PDS without any connective material at all. The rows I have on hand are even the perfect length for a NuBus Connector! They're snappable and three rows should be no problem, the only mod that might be necessary would be to sand/file a tad off each side of the center row's plastic or a bit off the inner side of the two outer rows.

The Machine Pin Sockets would be soldered to the SE/30 PDS Nubbins on the solder side of the MoBo.

I'd use ChipQuick and a heat shield along with a Heat Gun to yank the IIsi NuBus Adapter's RA PDS and Straight Up NuBus Connectors right off the card in one (actually two, but "one" sounds better) fell swoop!

The PDS Connector would be replaced with said Machine Pin Sockets while the Straight Nubus Connector would be replaced with the RA Version of same. That'll lay the NuBus Card flat, parallel with the SE/30 MoBo. It'll still be BackPlane forward, but that's actually a BIG PLUS!

Clearly, any number of SE/30 or IIsi Cards could be modified so as to stack neatly within the deepest darkest depths of the sub-terranian chamber of SE/30 hackin'horrors! [:O] ]'> [}:)] ]'> [;)] ]'> [:)] ]'> [:D] ]'> [:o)] ]'>

Here are some shots of the my Hackin'Connectors collection that I pulled out of the Magic Chest of Plastic Drawers™!
