If you just want to temporarily (until SCSI bus reset, or powerdown) alter
the Sony 8002 CD-ROM device to enter a 512 or 1024 byte logical byte block
transfer mode you could do it via a simple program utilizing the generic
SCSI driver. The program would merely have to do a mode sense command "1A"
with 0 pages selected and then alter the bytes in near location 8 of the
returned data from a value of 800h to 200h. This data is then rewritten
using the SCSI command MODE SELECT (15h). At this point, assuming a CD-ROM
medium was inserted the device is fully addressable as a 512 byte device
(useful for some purposes, such as Mac HFS)

This is merley conjecture, since I haven't done this on a NeXT before, but
have done it on other computers.
