Dwight,
I appreciate you taking a look this cable information. I have the MDS
signal definitions in the MDS schematics. I know what signals are on the
MDS end. I just have no way of knowing where they go

Does anyone have a
wiring
diagram of this cable.
Hi
I think I have it someplace. There are about 3 or 4 lines
that need to be twisted pairs with a ground lead. The original
used a bundle of twisted pairs that had black leads for the
one twisted lead. I many cases, the black leads carried data
signals and not ground. The cable manufacture only checked that
the cable had continuity and not that the right pairs
were twisted.
When I worked at Intel, I made a checker that would display
the number of incorrect twisted pairs by doing a transformer
coupling of the wires.
It may take me a while to look for the programmer cable
drawings. Hopefully, Joe or Dave can find one quicker.
