[amsat-bb] TAPR TNC-1

[James Cizek <jcizek@xxxxxxxxxxxxxxxxxxxxxxx>]

  Sorry to be a little off topic here, but I figured with this
  lists' resourceful people I might find an answer.  
  I have a TAPR TNC-1 Rev 2 (this is NOT a TNC 2) that I'd like to hook
  back up as a backup TNC.  I have no docs on it and haved searched
  the internet for hours to no avail (I found a picture of it though!!)
  Does anyone have a connection diagram or schematic for this beast?
  It has a DB25 Male DB25 Female and a DB9 female with markings
  indicating those ports as J1 J2 and J3.  The ROMS say 3.1 on them
  and the copyright on the board is 1983.  Any help greatly appreciated!!!
  Thanks!
