Well, I was part of the SCSI CD-ROM effort, and I know next to nothing
about the Soundblaster Pro board and the interface. If it is has some kind of
SCSI capability, then there should not be much of a problem. If this has
some kind of completely different interface then there would be a lot more
work. To begin with, I would want to know what the CD-ROM port on the
SoundBlaster actually looks like (both physically and as an interface).

I doubt it is anything like a SCSI port. Here is what is says in my
manual:
The Sound Blaster Pro has a built-in CD-ROM Drive interface which can
be connected to a Matsushita model CR-521 CD-ROM Drive. Detailed
connecting instructions and cable kits are provided when you purchase
the CD-ROM Drive from Creative Labs or one of their dealers.
-- and, in a different part of the manual...
I/O Address Map:
Base + 0H FM music Status Port (read)
...
Base + 10H CD-ROM data register (read/write)
Base + 11H CD-ROM status register (read)
Base + 12H CD-ROM reset register (write)
Base + 13H CD-ROM enable register (write)
-- The physical interface is a 40-pin connector - 2
rows of 20.
-- Well, that's all I know about it. I'll probably end up with a SCSI
adaptor anyway, because I'm going to want a tape drive sometime soon,
but since I have an adaptor, in theory, it might be nice to use it.
