Received a known working FPU today, along with its crystal and its socket.....
Only components missing from my board compared to the BBOAH's board is the circuitry for the SCSI side of it.


I believe you are mistaken in this assumption.

If you look at the image on BBOAH, to the right hand side where the jumpers are you will see that on the PCB it says JP1: FPUSPEED and JP1 is then in fact not a jumper, but in fact a DIODE solder onto the board.
I believe you will not be able to work an FPU in this board without installing the appropriate diode as pictured on BBOAH.

Don't distract from the diode that should be on the right, next to the jumpers.
