L2 Z80 LCD (Backlit)

Schematic 

     The 1734-BL1 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.  "BL1" indicates that this uses the upgraded NHD-0224WH-ATDI-JT# backlit display that has white characters on a black 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.
