Apple ][ boards -- what have I found?

The Ronan/Konan board does sound like a disk controller but I'm not sure about the Z80 chip? Maybe it's supposed to be a Z80 single board system, on a card? Are these cards for sale? I'm an avid Apple II and Apple II clone collector, so new parts are always fun to find.
