1) Prop accesses the SD card when CT952B is silent
2) Prop uses a file (file01-keys) to store the sequence of key presses from the demo board
3) Prop uses a file (file02-commands) to store the result of processing the alphanumeric, backspace, DEL, INS, OVR, arrows, etc for command line history
4) Prop uses a file (file03-font) to store the bit map table for a font suitable for the display, lets say 8x12 since I have one of those already
5) prop uses file (file02-commands) and file (file03-font) to construct a file (file04-DISPLAY-THIS.BMP) 80 or 100 character spaces wide and 17 or 23 character lines tall (depending on the resolution of the screen) that the CT952B re-displays as part of its stock programming.
Of course, the CT952B stock program only re-displays every 5 seconds so this would be a bit awkward, but I'll worry about that later.
I believe I would have to look at the signals going to the LCD. Is it using QVGA?
I see some RGB signals in the older schematic but can't find a V/H sync.
I'm not sure, but this looks a lot like the interface to the LCDs Rayman uses. At least you have the schematic pin-out on page 5 as a guide and can confirm the DC signals.

Prof Braino: Rayman's panel is digital (colors/intensities are bit-encoded, 6 or 8 bits per color). Your panel is analog (intensity changes with level voltage, 3 lines one for each color) two different beasts...

Groovey!
That means I can simply control the input to the existing hardware, and let it do all the work as normal, right? It auto-scales the images to the screen size, so I will make the prop add a single bit map to an existing image which is my test screen display. The file will be my screen buffer. Hey, if that works, I could have unlimited image size, and unlimited colors (up to those of the display and SD card size)
Panel has a 4in1 card slot SD/NMC/xd/(edit later)
Can anybody find a schematic? Otherwise I will harvest a micro SD adapter and use it to continuity test the slots pins. I guess I have to do this anyway to may the interface to the prop.

I don't know about QVGA yet, is there an easy way to check?
What do I want to look at with my fancy new old oscilloscope?
Maybe Rayman can help hack this.
Sent a PM to Rayman, Thanks

Could this actually work or will I burn my board?
Looks like the display is simple analog RGB, just like a VGA monitor...
