L3 Z80 LCD (Backlit)

Schematic 

     The 1734-B2 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. "B2" indicates that this uses the upgraded AMC2402AR-B-Y6WFDY backlit display that has Black characters on a Yellow/Green back ground. 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.
