ISA slots on an Emplant card?? :confused:
Or do you possibly mean accessing the ISA slots from Emplant software? There's simply no data path whatsoever from the Amiga side to the ISA bus.
If you want to make use of it you willl need a bridgeboard, connecting the Zorro and the ISA busses. The PC side can then access ISA and through additional software the Amiga may make use of it as well.
Actually, why all the fuzz? Use an external modem and that's it.
