In the next version, the screen will feel a lot more integrated. There is a bit of a challenge with larger screens as they tend to have more pixels and the MCU is pretty limited in how much it can push out at a good frame rate.

Use a RP2040 or similar to handle the conversion from the Spectrum pixel output to what the display needs?

And perhaps a small adapter board for the display FPC connector?

Been thinking exactly along those lines! But need to get this version actually done… so many rabbit holes :)

I know, just spitballing :)

Maybe mount the display on a small adapter PCB that has a CPU for pixel conversion, and a standard flat cable down to the main board?

Then the main board can stay the same even as the displays are swapped out together with new adapter PCBs?
