This project seems like a massive undertaking but you also seem to know what you're getting into. I admire your ambition, wish you luck, and hope to see more interesting videos about it!

Here's a HaD presentation I did on Veronica, which covers a lot of the unexpected challenges in a project like this.

Awesome idea... something no one from the retro-tech channels did so far. I'll keep my fingers crossed for you and am curious how the project comes along and together.

Joe, I am all in on this 6502 project. I would like to know: how do I get the proms you made to decode the 4 bits to the displays. Also, could you have just used one prom to decode and drive all 4 displays.
do you have a parts list?

Great project Joe! Will be following with interest. Think carefully about the graphics-capable video- if you want it, that governs all other decisions. 8-bit machines were all video generators with other stuff attached to them. The video/graphics hardware was the defining property of the architecture. I learned this the hard way while making my 8-bit machine Veronica. I went with bit-banged VGA, but wished I had used an FPGA for this, and wished I had better planned my memory map around the video. Also consider the F15A modern retro graphics chip. It's a very nice solution I wish I had known about.
