Check the PDS pinouts in the DevNotes for the two. There's a /NuBus signal on the IIsi PDS that's Missing on the SE/30 PDS.
I haven't checked it out yet, but if the NuBus Card in the Adapter is mapped to a different Slot Address than the PDS Cards in the IIsi, then /NuBus is likely the interrupt (whatever?) for for that particular Slot Assignment.
Take a look at the DuoDock DevNote as well, the NuBus Transceivers are identical(?) to the Transceivers on the IIsi NuBus Adapter and operate independently of the rest of the DuoDock PDS functions.
The Transceiver Chipset is made up of standard TI Parts and the Data Sheets are available online.
That's all I can think of off the top of my head at lunch time . . . :-/
Check it out! [}

ok with Nubus Card installed, The SE/30 Chimes.
Nubus NIC and Nubus Video card and just the The plain Nubus Adaptor Card installed.
The screen has that look as if rom is not installed and just sits there.
pull it off the PDS slot.. and SE/30 boots up and video is fine.
there is a 40mhz oscillator on the Nubus card.
just as there is a 40mhz oscillator on the IIsi for the CPU…
but as you said there is probably something missing as you said that makes this nubus adaptor card work.
the funny thing is on the NuBus card, no where does it say IIsi, it just says NUBUS ADAPTOR CARD APPLE COMPUTER 1990 820-0303-02

no problem now i can have nubus and fpu's in all my IIsi's
i have 10/100 nic cards for all three.
and hopefully if my ram testing goes well they will all get their one meg onboard ram removed.. and 16 megs ram installed, at one point.
and i now have a maccon ethernet card freed up for another se/30 + NIC + IIsi radius video card hack.

I'm fairly certain we can get it to work, but it's going to take more than a bit of research into the schematics of both machines to figure it out.
Bunsen has been at it a while, and of course, there is that Xpanse NuBus breakout box for the SE/30 to prove that something can be done about NuBus, whether it's within the capability of mere mortals to do so remains to be seen.
I'll be taking a look at the address swapping issues involved in the Gemini Card two NuBus slot in the IIsi NuBus adapter hack for the Super IIsi, dunno if that might wind up being applicable or not.
