Hello !
I also have this Scala but I just bought it with the CD32.
But I already had the SX1 and one day I hope I can put everything together.
I have even wrote to Scala (in Norway) but no hints from there as they just said they not support Amiga anymore.
I have that PDF-file somewhere and at that place I also have the utility disk. Haven´t tried it yet but I can try to found the file and look if it is working.
If you got anymore about this unit please reply and tell me as I also want to make it working properly.
The connection between CD32 and SX1 is very tricky and will fall in part and the SX1 is then not working.
