If you go FPGA anyway, HDMI signals can be generated. The obstacle here is to solder modern BGA chips as a hobbyist, and all the ground work to move from a classic chip to a modern one with more pins and more highspeed considerations. But in general I see this closer to realism than other ideas mentioned on the forum.Pr0f wrote:I have been thinking about this for some time too, and trying to figure out a way of getting QL video out of an HDMI socket.
There are several hurdles and problems, but some thoughts below:
1) QL screen memory use is a little strange in the layout - so that tends to rule out all but a large CPLD or FPGA to do the video so that compatibility is maintained

Since every modern FPGA suitable for HDMI has enough space to include a CPU, my question is: Would you still want the CPU outside the graphics chip, and why?
