   To Lap-Link Users,

                   Could someone please post the pin-outs for the serial and
   parallel lap-link cables. (I will be using Lap Link 3).

Here's parallel information.  BTW, I've found that parallel lap-link
cables are often called "Turbo LapLink" cables.

On the control pins, this is the truth table:

          0    |     1
--------------------------------+
 0 |  00000    |   01011        |      Upper set of bits is the value read
 0 |  00000    |   11011        |      on the left side.  Lower set of bits
--------------------------------+      is the value read on the top side.
