Nice. If you can divide down your pixel clock to roughly 8 pulses per line, and put a 3-bit counter clocked by that pulse, and reset by hsync, you should have colourbars. LSB is blue, bit 1 is red, bit 2 MSB is green.
Some interesting progress there. If you use the sync pulse as an input In sure you could bit bang a colour image to the screen with what you have here. The most ineffective way of doing it, but it would only keed one more wire from your current setup.

Steve, seus videos são muito legais!😃
Obrigado por compartilhar seu conhecimento!👍🏼
Eu quero montar para mim uma placa com z80 tambem!🖤

I'm pretty sure you don't need that inverter since it's the trailing edge of the write pulse that you want to latch the data.
Thanks. I'll try it without.
