Here's all I could find in the archives on the subject:

|Are you fed up with the cable that connects your UNIX-PC to its keyboard?
|
|I certainly am.  It is much too short.  So I am looking for a keyboard 
|extension cable.  If you know of such a beast, please let me know how I may
|get one.
|
|Murphy warns me not to expect such a cable to be available, so I am
|prepared to take this matter into my own hands.  
|
|Do you want such a cable?  If so, then please let me know.  Also say
|how long you think the cable should be.  How much would you expect such
|a cable to cost?  How much would you be willing to spend on it?  Should
|the cable be coiled or straight?  Please send me mail with your answers.
|I'll post a summary of your replies.  The more responses there are, the more
|likely some company would consider making the beast.
|
|I am accustomed to proping up a
|monitor on the far side of a desk, propping my feet upon the near edge of
|said desk, leaning back and typing with the keyboard on my lap.  The UNIX-PC
|keyboard cable is always fighting me.  It looks neat sitting on the box, but as
|soon as one pulls it off the box and sits it down in front of the box, the 
|coiled cord starts pulling.  It probably would have been long enough, if it
|hadn't been coiled.  Does anybody know how to uncoil it without unduly 
|stressing the conductors?
|
|I myself, have the means to splice in some extra wire, but it wouldn't be
|as nice as a cable done right.  I would sure like to see a good long cable.
|
|My own empirical ohmic study of the cable has established the following
|connections as looking into the ends of the cable.  The numbering of pins
|is my own.  The ends are identical.
|
|  Bare
| Shield
|  Side

||1|3|5|7|

|  One End     Other End

|     3            3
|     4            6
|     5            5
|     6            4
|     7            7
|     8            8
|
|Notice how pins 4 and 6 are swapped, similar to that of a null modem.

|I promised to post a summary of replies to my questions about how
|much a keyboard extension cable for the UNIX PC is wanted.
|
|I received only one reply, which makes this compilation easy:
|
|Respondant               myself          Gary Falsken
|                         ------          ------------
|Length                   12 feet         no response
|$ Expect to See          $35 to $50      $10 to $15
|$ Willing to Spend       $60             no response
|Coiled vs. Straight      straight        *both*
|
|It looks like I'll be splicing in some cable myself.

I have the dope on ordering cables at work, but probably
won't be able to post it for a week, as I'm heading to the
airport for a long business trip.

What I do recall is that I ordered my cable from the Connector
Division of DuPont, and it was someplace in Pennsylvania.  I
have the original Convergent part number, address, and phone
number squirreled away;  I recall it cost me $20 qty. one.
