DSI won't work currently , it might be possible.

Interesting sounding project! What hardware is required to connect the Pi to the 1MHz bus? Obviously a level shifter of some sort but what are the specifics?
Thanks!

The 1989 version of the manual does mention RISC OS, so my guess would be that is was written with RISC OS 3 in mind (no version number mentioned anywhere).
It was more likely with RISC OS 2 in mind. RISC OS 2 was called RISC OS before RISC OS 3 came out in 1991.

Knowing the possible wreckage caused by the high voltage psu I’d suggest to start with the basics; check for 5V supply on the IC’s on the main board and check if the CPU gets a clock signal (does it have a pulse?).
Everywhere where I checked untill now was 5 V.
The pulse on the cpu:
