Well, I think the explanation is simple, SoftLA isn't FAST enough to pick
up the CS or EN signals. It's fastest timebase is 5.88us and I think that
won't work in this application. Need to SLOW the system down. Perhaps a
slower crystal? But I don't think this is going to be as easy as I
originally thought... Anyone here with a Logic Analyzer that is
interested in taking this project on?<br><br>

the coding to the Pod from the base unit using a really nice

for about $30US. <br><br>

If I tell the Pod to do a BUS test, and I use CS as the trigger point I get a RESET <b><i><u>BEFORE </u></i></b>the 6520 is SELECTED...psychic...it knows it is wanted. Is anyone here more familiar with the programming ins and outs of the 6520? I think FLUKE might have used an undocumented (in my reference book by Rockwell) data call to the PIA that seems to enable PORT A to output data WITHOUT the CS or EN.<br>
