I had the above drop into my lap recently. It is clearly a Daystar Digital Universal Powercache P33 fitted with a FPU and 68030 running at 40mhz. What I was hoping is if someone could confirm my suspicion that the adapter board attached is for the SE/30. I have absolutely no way to test it as the only 68k Mac I have is locked in a Duo Dock Plus (no key either).

I appreciate any help I can get with this thing, documentation is very sparse.
