I think a flaky problem with my Duo-Disk drive (which I use with a IIe)
may be due to a break in the cable somewhere.  I'd like to test it
myself for continuity, so to save myself the fees for the repairman's
time and just buy a new cable if that's what I need.  Can anyone tell me
which connectors are crossed, and which are which?  That is:  I know
that some cables cross, say, 3 and 4, so that 3 on one end connects to 4
on the other instead of 3-3 and 4-4; but I don't know which one is 3.
Advance thanks for any help.
