Many, many manufacturers of boards for the IEEE S-100 bus use the vectored interrupt lines. (After all, the Z-80 knows how to handle them, right?) Well, the folks at ADS haven't set the board up to puzzle out vectored interrupts for the 6809, either. So--I'm basically wondering how to connect the vectored interrupt lines so that they show up as input to one of the on-board parallel ports. If anyone out there in CRT-land has done this, or thinks maybe I'm barking up the wrong tree (in the sense that there's a better way to deal with vectored interrupts and pass the data on to the 6809; Z-80 bigots need not reply), I'd greatly appreciate any information you could pass along.
