It appears that the 560X model does not have a CD option. So it would have to be an external CD. It looks like it has a 1.0 USB port on it. It was made in 1997, so I am guessing USB 1.0?
Google is no help, tons of stuff, forum postings, etc. Or it could be because I have a big headache and a headcold? Anyway my brother is looking up parts for it. I might be getting one discounted or free because I helped my brother put Windows on those laptops without a CD-ROM drive. Nice use of a Zip Drive and PCMCIA Ethernet card. :)
