Oh, right you are - I hadn't worked that out. (Probably because my head is still full of KT24 stuff, which doesn't have two totally separated busses. :-) > That assumes the KT11-B does only memory mapping, not the other things > that other MMUs do (user vs. kernel mode, I/D space .. ). I don't think it can; those would require hooks into the CPU, and there are no signs of such, in the pictures. Noel
