so lift and ground the pins you mentioned, and pins 20, 26, 33, 40 hooked up with the resistors per the diagram?

shouldnt be needed

Well actually...  I have a plan to make an LT from one of my PC Engines.  Which involves finding a 4:3 LCD of about 4.5" and moving some crap around....  Maybe even include a battery.

Oh snap you're right.  I remember the MMMonkey guide now.  Sorry, it's been a while

That isn't difficult. The PS One screen is a good candidate and you can even hook it up with RGB. I have one I did posted somewhere.

You beat me to it duo. The ps one screen works great, and can be bought brand new for around $45. That sounds like a pretty slick project you're thinking off soop. If you get around to it, make sure you post pics. I would love to see it.

The PS One screen is too big (I think even with work it won't fit inside the PCE's dimensions - but I do have a decent screen saved somewhere on eBay.

I'd love to see your work though if you can find it!

Tat, why go composite when you can go component with this:)
