Still more data on the ADS 6809 SBC, and a plea for help:

As you folks out there have probably read in an earlier letter, the 6809
doesn't know from vectored interrupts, and in trying to use the ADS 6809
SBC I'm beating my head against that now. 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.
