Killer stuff, good to see so much information come to light, nice job! Glad to get confirmation that the inter-board connector in the corner was for a graphics card. You don't happen to have that do you?
I envied folks who got later accelerators such as yours for the SE that supported onboard RAM and Compact Virtual. Mine came with the Radius16, 68020 installed, which had no provisions for the Virtual Memory hack. The speed was great, but it was the FPU that gave vectorization/vinyl plotting a huge kick in the pants. It made TypeStyler usable on the SE as well, heard it was a real pig on a stock SE. Never did get the FPD I always wanted, graduated to a low rent TPD when I got the used Mac IIx. What a difference, it was like moving from a sleeping pad for backpacking to a king size mattress after having been stuck doing graphic design on the SE's Periscope.
Sorry about not having clarified, I was in the process of going AWOL for a few months right after that, so I wasn't paying strict attention. As I understand it, there must be drivers in ROM on your Accelerator to turn off the 68000 and run the 68020 in its place. In the case of my Radius16, a driver was required to do this, IIRC.
As for the second sentence: NuBus Mafia PDS Accelerators . . .
. . . and oblique reference to using the DuckDuckGo search engine as opposed to the personal info hoover that is Google.

This didnt really make sense to me. So you are saying that I have to keep ram/rom in both boards correct?? No idea what that second sentence means..
