The SWIM chip can act like an IWM one and there is a procedure to know in which mode it is.
That is good to know. Hopefully that can also be used to detect which chip it is, possibly by checking for a mode change failure.
If we suppose the SWIM chip on MacII is at the same address than the IWM one, we should be able to use this procedure to know if it is an IWM or a SWIM.
It would have to be the same address, since the address decoding logic is part of the bus interface circuits on 68k macs. Each IO chip just has a chip select and a few address lines based on what I've seen.
