Here are some general pinout notes on the DIF-AT RBUS and Digital Audio flow, and the connections to the Alesis Chip (which seems to do all the heavy lifting as regards audio and timing) All audio formats go directly into the Alesis chip. The Xilinx chip is handling RBUS only.

Here I will refer to the excellent site of Chris Xiong who made a converter from RBUS>ADAT (but not bi-directional) He covers the technical aspect of the RBUS signal and pinouts etc here in detail -

I didn't go much into the TDIF as I don't have anything TDIF capable. Both RBUS and TDIF are long obsolete, but ADAT is still going strong. https://www.panix.com/~jens/da-88/tdif.html
However this is only between TDIF and ADAT.

I will update this when the device is fully tested. For now, be assured that it's back together, repaired, and starting to boot. There could be some small issues, which can be discovered and fixed with the UART function. I could only continue the marathon with a reboot myself.
Thanks for reading. I hope it's interesting and or useful! If you want the Cutter project file I can send it you, email me through the site. Or any questions I'd be happy to answer.
