RE: Fluke pod cables (related to 6502 pod)

Just thinking aloud, but what about the newer 80 core IDE cables, they seem
to be used with normal(ish) 40 pin IDC connectors, but have the extra wires
to cut down crosstalk - plus you can now get round cables and all sorts of
variations for the case modders - these support DMA133 mode so must have a
mechansim to cut out the crosstalk again

  Hello,

      I'm new to this group so I hope that this message gets through. I
found the same problem (pod fails/works with shield connected/unconnected)
with a pod cable on a z80 pod that I recently purchased from Art AS IS only
the internal short to the shield was on pin 2 (A12). Must be a degradation
over time in the insulation which was used inside the 40 pin DIP connector
of the pod cable. I fixed mine by bypassing pin 2 with a 40 pin socket
adapter. Hearing this, I now will expect that this can happen with all
original pod cables over time and will need to find (make) a suitable
replacement. To debug it I used a flat ribbon cable from an IDE cable and
added a 40 pin IDC connector. I put the ribbon cable back on the pod and am
learning how to use the 9010A - I don't think that the unshielded cable will
hurt me in my low-freq. application (repairing pacman boards). For other
pods / higher freq systems, I think the twisted pairs cabling will be needed
and I won't buy NOS Fluke replacement cables as a solution.
