While searching for the post you mentioned about the PDB and SX chips, I came across this thread: http://forums.parallax.com/forums/default.aspx?f=7&m=83563 in which Ken stated that the SX Tech board cannot be used to program Sx18's because of pin differences when compared to newer chips. In fact, one poster on that thread had the same error as I mentioned before (but it did not show up in my search). I'll try Ken's suggestion of using a breadboard and wiring the connections up myself. This is all strange, though. I know I programmed this thing (SX18) with one of my two boards! ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=84242#m84250 Need assistance?
