Yeah, the RRD40 was the one with the special DEC caddies where you never
had to touch the CD. I think I still have one somewhere. RRD42 used the
standard caddies, and was double speed I believe. RRD43 was the one where
the disk snapped into it, and the RRD45 was the 4x speed tray one, and the
RRD46 was the 12x speed tray one. I'll have to see what I have. Its more
than likely going to be an RRD43 though, but I would think it would work.

I may give this a shot then. I think its my best option.
