Looks like the company also made a PCI to Nubus bridge, and there was a requirement for 32-bit clean applications.
The closest thing I found to a technical note so far is:
7.2.1.4 PAL DEVICE. A 16L8 PAL is used to generate chip select signals to the DDLC and '374 address expansion register. The...
Try https://www.savagetaylor.com/wp-content/uploads/68k_Macintosh/Bootdisks/320_32MB_volume.zip. I initialized it on my Plus, and was able to boot using my FloppyEMU, what I don't know is if that added the MBR
So no luck on the document so far, but Alan Oppenheimer did respond
"I have lots of other documents, and if I ever retire, maybe I'll organize them (I gave a bunch to Stanford many years ago too). Right now I'm way too busy (big intro next month; see artauthority.museum). It would be fun to have...
Interesting, I wonder if we could make a modern version?

Ditto, I do most of my setup using an emulator like Basilisk II and then just copy everything to my 68k macs, either over the network, or by editing the contents of a single volume drive image on an SD card that I then use with my ZuluSCSI, BlueSCSI or MacSD adapter.
I have guides on my site on how to update to the full version, typically I use Basilisk II to do the update using Apple’s Legacy Software Recovery CD from the Internet Archive as the source of the update files. Because you have the PiSCSI, you may be able to put the Legacy CD image directly on...
This is Steve from SavageTaylor.com Did you update my image to the full version of 7.5.5? I have an actual Asanté device that I use and it needed the full version of the system installed to work properly. I have a guide for the Plus and 6.0.8 on my site. I hope to experiment with the piSCSI...
Well, as a long shot I just sent Alan Oppenheimer a message on LinkedIn, he presented at WWDC 1990 about Apple Talk Phase 2 and referenced the document you are looking for. He was part of the original Macintosh networking team.
