The soldered over thru-holes on this card may be very useful for the original purpose!

I got some sporadic flakiness using it "as is" (FlatCardStackConnectorHack™ aside) with the Radius Color Pivot II/IIsi card. Adding the 10bT card might cause more noise, so zeners mounted on the modded SuperMac PDS Adapter might wind up being just what the EE ordered!
