I am attempting to write a simple oscilloscope program for my Atari 800XL, and
have run into what appears to be a snag.  Although I can appreciate that the
accuracy of the reading may be reduced by a few significant bits, it appears
instead that, depending on the pot value, *most* of the readings I get are
completely bogus.  I *think* I am doing all of the necessary steps in the
correct order, as specified in Atari's Technical Reference Manual for the 800.
Has this interface changed somehow for the XL series?

I will, of course, summarize any mailed responses.  Thanks!
