Believe it or else, about three years ago I posted the following
to the old list. Thanks go to the retrobytes.org folks for
putting it into a webby archive that is searchable by Google.

On NCR gear? News to me, but what do I know?

Should you happen to run across NCR Tower serial ports on DA15
connectors, the adapter cable that brings this out to a male
DB25 connector looks like this.

Both hoods have the following molded into them:

   One side:
       TERMINAL
    1308-C036-0152

   The other side:
     006-0089359
     U.L. E40323

Ohming it out yields:

    DA15 DB25
                1 - frame ground
      1 ------ 3
      2 ------ 5
   3,12 ------ 4
      4 ------ 6,8
      9 ------ 2
     10 ------ 20
     11 ------ 7

I used to use this cable to hook up an HP 700/22 to an NCR Tower's
console port. I can't remember whether I had it plugged into a
null-modem-like thing or just a gender bender at the 700/22 end,
but there must have been something there because both the cable and
the terminal have male connectors.

Hope this helps someone.
