Sometime in the long long ago the m68k IRQ code was refactored and the interrupt numbers for SCSI on this board ended up being wrong and SCSI hasn't worked for a few decades... The PCC adds 0x40 to the vector for its interrupts so they end up in the user interrupts naturally, the kernel number should be the kernel offset for user interrupt numbers + the PCC interrupt number. Basically they are 0x40 off right now.
