Connecting Toshiba TLX-711A display to LPT port
Below is the schematic that I used to connect my Toshiba TLX-711A display to the computer. For the negative -7,8V contrast voltage I made a circuit based on MAX764.
Displays PCB from behind.
Two different circuits for the -7,8V contrast voltage
Data sheet for MAX764 is here.
