Thank you very much for the kernel! I did a quick test and this is my result (all emulated):

NeXTcube: works
NeXTstation: works
NeXTstation Color: works
NeXTcube Turbo: bootloader thinks it is non-Turbo (type 8, which is in fact Turbo) and crashes while trying to read bmap address 0x020c0034
NeXTstation Turbo: works
NeXTstation Turbo Color: kernel tries to access registers, that do not exist on Turbo Color (only on Color): 0x02118180, 0x02118190, 0x02118198 (color video control and memory timings)


The SCSI problem still exists. I suppose the fix for that was not included yet?

Best wishes,
Andreas
