Hi George,

Yes, there are always a number of different ways to "skin a cat" but if I went with the logic analyser route then I would have nothing to design and build using a PIC

If we end up with more than a byte's worth of fault counts on any of the nine data lines within a one minute test period then we have more problems to worry about than a PIC running out of memory!
