What I am trying to figure out is are both my pods bad (which I doubt as two
are behaving the same way) or is my 9010.

Our 8080 pods have the OEM twisted cables. Our 6502 pods (re: Clay's
Tempest question) come in both twisted and the flat cables. I'm assuming
the flat cable is a non-factory replacement item, but could be totally wrong
about that. The 6502 pod that failed just happened to have had a flat cable
but I'm confident the drive problem was unrelated; we found one specific
driver output that wasn't going sufficiently high once plugged into a "real"
target board. It wasn't a general malaise of the address lines like you
might expect from transmission line losses or higher EMI susceptibility due
to the flat cable if that's what you are wondering.

>Are you using a 9010 or a 9100 to drive the pod?

Both...
