Jaguar LCD project


8bitdomain

Recommended Posts

Here is an project I built as a RGB test monitor for arcade games but has been

attached to a Jaguar for gameplay. It is based on a Sharp 5" LQ5A136 display.

The monitor has the needed 15Khz Hsync and has built in backlighting.

The controller board I built contains the backlight inverter, power supply which

takes a 12vdc input and provides the +5, +8 & -5 for the LCD. Dip switches to

select PAL or NTSC, InputA (DB9) or InputB (8pin header), Pos or Neg sync selection

and an unusual horizontal flip or vertical flip mode. The LCD's alone are normally

$300 but I was able to find about 10 surplus units for a reasonable price. See attached

pictures for detail on the controller board and running Doom. If there is any interest

I could build up a few, however the price would be a little steep, around $138 complete.

Pardon my ignorance - but wouldn't it have been a lot easier to go buy one of those small LCD monitors that take an AV input? You know, like you see parents putting in the mini-van for the kids to watch DVDs on?

 

Yes it would, but the origional goal was to be able to test arcade boards (Williams, Midway, etc.)

So having RGB inputs was a must. Having it work for the Jag too is just icing on the cake.

And Jag can do RGB from the SV port which blows all others away

in quality as that is the abolute direct signal most display devices

break down to anyway. R,G,B, Hsync, Vsync. This is the REAL deal.

I use one of these for my Jag development. It good to do vertical

monitor games on too.
