You would probably only need the I/O space on the PC side to be mapped into the Amiga side's address space. Then you could get to all those cheap PC-bus cards to drop into your Amiga. Sure, you still have to write drivers, etc., and figure out how to map the PC interrupts to the Amiga. They could be concentrated into one interrupt and distinguished by reading a register on the bridge. Has Commodore already thought of this one? -- Randy Rorden, Icon International {ihnp4,decvax,seismo!ut-sally} 774 South 400 East, Orem, UT. !utah-cs!utah-gr!uplherc!nrc-ut!iconsys!rorden
