hi all, can anyone tell me where i can find some docs about how a vga works?
i'd like to know if it's possibile to interface it on a 6502 board.
tnx!

There is a little bit about it in this document, but I'm sure there are better.

i think you hit the point!
tnx, it seem to be a good kickoff.
next step maybe can be find out a onechip vga controller.
tnx again

Interesting stuff!

I'm currently working on CGA controller based on 6545 CRT chip.

I went ahead and ordered one of the Hess FPGA boards. I may build their vga model. Using the FPGA could also allow for other options such as IDE, Compact Flash, ethernet, and also DRAM refresh control.

Anyhow, I've always wanted to give FPGA design a try.
