Ok, I got this all loaded , got some help from Peter and am able to
drop these pins to ground and watch encoder raw count show pin

think I reverse biased this led and popped it. I have another encoder
and motor to try to read counts on. The real question, this is a heads
8950 and it shows eol as Nov 2011 and I cannot locate a source for a
replacement. Which would be great as the omron encoders are in China
and will require fabrication to install. Any recommendations?
I am lost at "heads 8950". Whats that?
HEDS is a line of old HP encoders, now sold by Avago. You
can look them up on Digi-Key, there are probably over a
thousand combinations of encoder wheels, read heads and covers.
There are other units with different 4-letter part numbers
that have more channels, differential outputs, special
housings, etc.
A few other makers also make form-compatible encoders with
the HEDS part number, which MAY be compatible with the HP
part #'s.
