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?

Well, I've been trying to interpret the coding to the Pod from the base unit using a really nice software/hardware tool called SoftLA. Software Logic Analyzer is what it is, 16 channels! You can get it from www.BGMicro.com for about $30US.

If I tell the Pod to do a BUS test, and I use CS as the trigger point I get a RESET BEFORE 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.
