Has anyone found a mini LCD or TFT screen conversion for the 3 main monitors ? Also has an members made a CGI or VIDEO boot up for the animation? I have found a few possible set ups but would love to have some input if anyone has already made the upgrade. Thanks Randy

I know you are looking at various screens and are testing some from Adafruit. What are the sizes that you are looking for? I ask only because there is disagreement on the actual dimensions of the machine and that directly effects the screen sizes. Personally, I am using screens with 4:3 aspect ratio and for the 2 small screens I'm using 2.5" diagonal and for the larger screen 5" diagonal. Another area to consider is what type of interface you would prefer to work with (such as SPI, UART, Component Video, HDMI, etc.)

I can't really offer any advice on screens. I've been taking most of my cues from LBM's build for the smaller screens.

But the sizes of the screens really sets the size of everything else. Before Christmas I bought a second hand mini TV/radio which was described on the box as a 4.5".

But when it arrived the diagonal was actually 5". Which is too big for the machine I want to make. Also the component video inputs didn't work correctly. I was able to send it back but I should have asked more questions up front. I guess 35 year old technology is going to be problematic.

With the LCD panels there doesn't seen to be one in the size I want for the larger screen. Its either 5" or 3.'5" and smaller.

I've noticed that there is a viewing angle on some of the LCD monitors and I'm not quite sure what that means. If it has a 6 O'clock viewing angle does that mean its best viewed when lying flat!?

So until I find a solution to the screen sizes I want I can't start making.
