Indubitably, but it's hardly an impossible task. I've been suggesting a collaborative effort on a clean-room (Atrmix-untouched) approach to reverse engineering the various SuperMac IIci slot adapters for quite a while now.
Matter of fact, mcd sent me a SuperMac PowerCache Adapter for the Mac II so's I can isolate the CPU signals from the PMMU signals involved. It's a WAG on my part that such might be helpful, but we've got plenty of talent around here do hack the SuperMac logic and build a better card than the pricey one form Japan. Ours ought to have as all the pass-thru connectors in all the right places where an SE/30 or a IIsi can support them. i.e. at least one more than the Atrmix board. [}

ISTR techknight telling me that the necessary logic has something to do with re-mapping the address space of the PDS slot to that of the IIci Cache Slot or some such.
