An interesting problem! How do the HDMI cards look? I have one but my Apple is not working at the moment at I haven't tried it yet. They are clever devices that snoop the bus and replicate the video do it might not be suitable for demo purposes. Then again, they are programmable hehe

I have to admit I'm being difficult here and want to capture the output of the composite port from the actual Apple II video circuitry. I feel like having a raspberry Pi replace the video circuitry is cheating somehow, and I know that's inconsistent of me because I'm often using a modern floppy disk replacement.

even if I had an HDMI card it wouldn't help with my other problem which is trying to capture HDMI video and mockingboard sound at the same time with them ideally synced up to the exact 60Hz frame
