That would also make it fully compatible to Q40, Q60 and Q68. Still I'm reluctant to recommend the PC pinout - I understand the Tx as a strict retro board, so it makes some sense to keep original QL equipment like printers, printer interfaces or QL-taylormade serial cables directly usable.

Yes please. It's essential for a board like this.

Yes please. Not to forget the Q68 - which probably has more active users than QXL and Thor these days.

I differ here - to only integrate new sound seems a totally arbitrary choice. Others might prefer QIMI (or other mouse port) integration, others memory expansion integration, others better video, etc. If a relatively rare card like Qsound is added, then where does the choice of features start, and where does it end?
For my taste, this
board should remain close to the QL, a replacement with moderate improvements for quality and manufacturablity, but no feature creep. I'm not against a new mainboard that massively upgrades the QL - but that would be a totally different project in my opinion.
