Hi @ijor, long time no see. Thank you! I'm doing quite well, just a few health concerns these days. My warranty ran out in 2020 it seems. How are you?
I understand Intel may need to prioritise their military customers and do what they can to avoid SLA penalties for their industry contracts. It's annoying, but understandable, that we must just wait and see.
It still needs an outbound connection to HSYNC to inject the doubled HSYNC into the video-out circuitry though - so no matter what, it will need at least one soldered wire for HSYNC, and another for BLANK (also an output). I also need one to detect VSYNC in order to generate the vertical part of the blanking. Considering that soldering these wires is already necessary, the cut track and the extra wire for HSYNC (inbound) is only a small amount of extra work.
As HSYNC from the GLUE is - presumably - always TTL logic (you'd know better than me), it may have been possible to leave the HSYNC track uncut on the PCB and have both the GLUE and this mod drive the line at alternate times. But I didn't want to take the risk of damaging someone's GLUE. A cut track is easily repaired, not so much with the GLUE.
I agree with you that most people would like a plug-and-play mod, if that were possible.
