I have an old graphical LCD with 4 M5260 chips and 1 SCI7661 and a 10 pin connector. I know SCI7661 is a DC-DC converter. I would like to interface it to the parallel port and need help with working out how to do it.
If LCD pbc contain only four M5260 and DC-DC converter you can't connect that LCD directly to LPT port. For working with LPT display must have graphic driver on board.
