Card Edge connector was the parallel port of choice on model 1's, 3's and
4's and vertain model 1000's.  Also IIRC the mod 2 , 12 and 16 may ahve had
a card-edge parallel port.

seems to be a speed-dialer of some sort. The other is a
cable with a (Doc ducks & prepares to rub) 36-pin Centronics connector,
plus eyelet ground, on one end and a female card-edge connector on the
other. The shrouds are steel, squared, and embossed "TANDY" on both
ends. While I've never seen one, I'm guessing it's a Tandy printer
cable. 
         That's the general description of the parallel printer cable to
 the Tandy 1000-series machines before Tandy switched to a standard
 connector on the CPU.  I've got one here with my 1000HX. Unfortunately
 Tandy used a number of different connectors for the parallel ports of
 their early machines, including a dual-row header and the above mentioned
 card edge connector.
