Thanks for all the responses - I read through all, but I am just 
responding to the latest.  As others have stated, the straight through 
cable is valid - I found a use for the spare Ms Pac 40 pin connector 
cables I have laying around.  Since I do not have any 40 pin DIP plugs 
on hand I lopped of one end of the Ms. Pac cable and crimped on a header 
socket for the pod side and all seems well at this time.  The header 
pins on the Pod side are still solid, but I did verify on the old cable 
that a couple wires on each end are loose/broken at the connector so I 
should be able to save the cable.  It will likely take some time and 
should be a whole pile of fun getting a new end on it, but the UUT side 
is fine so it will be worth saving it.  For now at least I can continue 
my tests.

Now I need to look at the other Z80 pod I have as a spare, it was 
passing self test for the first minute or so and then failing after 
that.  Tonight I clamped the plug into the socket and let it sit looping 
the test and it seemed to stay in a passing state.  I suppose it was 
either a dirty socket or pins but I didn't wiggle the cable around.  
I'll see how it acts tomorrow.

Thanks,
Greg
