L1 Z80 LCD (Reflective)

Schematic 

     The 1734-TF is an LCD add on card that mounts the the 1731 Backplane. The LCD is arranged as 2 lines of 24 characters and interfaces directly to the LCD driver of the 1730 Z80 Computer.  "TF" indicates that this uses the low cost DMC24227 reflective display that uses room lighting for illumination. The display mounts to the backplane using the front or rear edge/corner screws and has standoffs in the front for support.  The pins used to mount the display are left long to aid in probing.
