Q: does this pass all signals from STE video port to pins on VGA? I am wondering if it would be possible to plug the VGA output into a GBS8220 scan doubler... and whether that device then would double LO/MED but not HI ?? Curious

Does this work for STE? other STs? If so would be great if someone could change the thread title to stop idiots like me asking what may well be obvious to others?

Q: Would this work still with the original 520 ST (not STFM)

Automatic detection and switching of resolution (requires software implementation).

What does this mean exactly? ST software needed? Or what... I can find no info anywhere... Thanks

Thanks Chris. Old age and poor eyesight... I think this design is the booster for me then if it gets to production

Did I imagine it or did Chris re-design this WITH an IDE.. I could swear I have seen a new PCB design.. or was it all a dream?
