Can someone take some really high resolution pics of the NuChip and Transceivers that make up the NuBus Bridge Chipset that would be appropriate to the SE/30's IIcx Architecture roots.

Will these suffice? (click on the images for a large version, around 3.5 MB each)







I thought the main culprit of the SE/30 not working with the IIsi NuBus adapter was the extra FPU... but did some experimenting and got interesting results:

NuBus adapter with soldered FPU: chimes, but zebra pattern and no boot. Pressing reset repeats everything, including the chime.

DaynaPORT E/si30 NIC socketed: does not chime at all. Shows more or less distorted version of the last displayed image, if not disconnected for long. Pressing reset doesn't change anything (no chimes either). Further testing did chime sometimes, or made strange sounds, or death chime in a standard, slow-tempo, distorted or low-pitched way...

SuperMac PDS pass-thru: does chime the first time, and zebra pattern appears. But it does not chime after pressing reset, only after a hard power-off.

Radius Pivot: zebra strips, but no chime ever... although it started making awful sounds after pressing reset, but just once.

It goes without saying, all of these socketed cards do boot fine on the SE/30 once the FPU is removed. SlotInfo recognizes them properly. And the IIsi works fine with the FPU on them, and it's recognized too.
