I'll go into a bit more detail about this side project in the next dev diary shortly, but here's another sneak preview of the LEX500. It's a fictional low-res machine designed for hacking out little games quickly and sharing them on the BBS. The resolution and data storage size is quite limited to encourage making something small and interesting.
I'm planning to have a fixed 16 colour palette (including transparency) to further prevent extra work the designer might feel compelled to do. This screenshot is just a test for the palette, showing an example game scene and different ways the 16 colours can be used together. If you have any gripes about the palette, let me know soon!
