I dig out my NeXTstation slab and prepare a SoundBox cable for
Brian Archer's custom Non ADB interface:

Then it looks recent NetBSD/next68k GENERIC kernels including 9.3 have
several problems:

 9.3:   Ethernet doesn't work, keyboard doesn't work, SCSI doesn't work
 8.2:   ditto
 7.2:   Ethernet works, keyboard doesn't work, SCSI doesn't work
 6.1.5: Ethernet works, keyboard works, SCSI doesn't work
 5.2.3: All Ethernet, keyboard, and SCSI work

So trying 5.2.3 binaries might be worth to debug emulators:

dmesg of NetBSD/next68k 5.2.3 is here:
