To connect the LCD to the parallel port I wanted something clean, as well as for the contrast and luminosity settings.
Not to forget a reset switch and the +5V connection.
For the LPT1 connection I used a 36-pole Centronics connector, so I was able to use a standard printer cable.
The whole thing is mounted on an alu profile of 20x30mm that will be fixed on a plexi standard.
The LCD itself will be mounted also on this plexi under an angle of about 70° (I can pick up the plexi this afternoon)
For the cable to the LCD I used a "cannibalized" 40-pin IDE cable. The LCD has 20 pins, so I used only the lower row of the 40-pin connector (1 wire on 2).
As I didn't want any "flying" components I developped a little PCB:
From left to right:
Reset switch, contrast, luminosity, +5V-connection.
Actually power supply is done via an external ZIP100 PSU (exactly +5V), but afterwards I want to connect it to the Enermax +5V rail in my PC-70.
Therefore I decided to include a fuse onto the PCB.
Rear view. The knobs are still not mounted on the trimpots.
