- Mar 1, 2007Bill,
Looking at the photo showing the missing chip,
it appears that you may also be missing a few components
in the O/I section. (or is that I/O? :-) ) I see a place
that looks like it had a transistor, and two pads that look
like a resistor was once there. Maybe it's the difference
between 20 mA current loop and RS-232 or something.
Nice pictures, BTW.
