v0.3 Schematic and Gerber available now. This revision has been tested on my two TI-99/4As (PAL and NTSC) and my HBC-56 and is fully functional, however it is not representative of the final PCB design which will include the RP2040 directoly on the PCB.

I could reduce the VGA bit depth to 9-bit or 10-bit to allow the use of a genuine Raspberry Pi Pico board, but given the longer-term plan is to use the RP2040 directly, I've decided to go this way for the prototype.

## Development environment

To set up your development environment for the Raspberry Pi Pico, follow the [Raspberry Pi C/C++ SDK Setup](https://www.raspberrypi.com/documentation/microcontrollers/c_sdk.html) instructions.

#### Windows

For Windows users, there is a pre-packaged installer provided by the Raspberry Pi Foundation: https://github.com/raspberrypi/pico-setup-windows/releases/. Once installed, just open the pre-configured "Pico - Visual Studio Code" from your start menu.

The build system expects `python3` to be available. If you have installed Python 3 outside of the Microsoft Store, you may need to alias your Python executable.

You can do this from an elevated (Administator) command prompt in your python directory e.g. `C:\Program Files\Python310\` by creating a symlink with the command: `mklink python3.exe python.exe`.
