Hi all,
I pulled apart an old HP LaserJet-II and found the LCD is a really
neat assembly.
I think it is a 1 line, 12 or 16 characters.
has 3 statius LED's
2 LED's on membrane switches and 4 additional switches.
Internally it has a buzzer
HD44780A00 chip on the display and a pair of 74ls14 chips.
Has anyone hacked one of these ?
it seems like a great and rugged starting point for a hand held unit.
