PR2040 VT100 Terminal with Parallel TFT LCD. Work in progress!

Overview
The main purpose of this design was to learn about the RP2040 scanvideo library components and utilise them with a Parallel TFT LCD. Parallel meaning the interface uses HYSNC, VSYNC, DEN (currently not used), PCLK and RGB[5] signals.
I am currently using this with a Sharp LQ042 LCD with a resolution of 480x272. This works perfectly with a 8x16 Font to give a total of 60 Columns by 17 Rows.
Appearance Breadboard Version
Appearance PCB Version
Here is the 3D render of the general layout. Schematics, gerbers and other support files are now available. A few improvements to the PCB will be made over time, specially I want to add the RP2040 directly to the board and not use a Pi Pico. This iterration is more or less a proof of concept.
