I guess the required signals don't appear at the Zorro bus to handle this sort of thing internally. With that said, I wonder if it's feasible to do something exceptionally sh*tty, like grab the RGB/CSYNC signals from Denise using an additional adaptor, feed them to the card, and process/upscale them to output via HDMI using the onboard FPGA when native video is in use?
The signals out of Denise (and prior to VIDIOT on the A2000) are digital, 13 signals in total assuming we'd only need R[0:3], G[0:3], B[0:3], and CSYNC - Conceptually it wouldn't be all that complex of a task for an FPGA
The video signals are present on the Zorro III bus, but the guy designing it did so for his 2000.
The Picasso IV had the genius design of having a circuit board you could snap and put into the video slot of the 2000 and connect back up to the board in the Zorro slot but I guess that would have been a lot harder to implement on this project; especially if he really only needed it for productivity software etc.
