Absolutely, I can't imagine doing this on an 11/44 with out the
documentation. I did this very thing with a bunch of corvus concept
boards about 10 years ago. Decoded (coded ?) the 68k peripheral chip CS
lines with a latch, the 68k will loop through its address space it you
ground DTACK.

 Brings up another topic: Anybody got a Corvus Concept?
