But will cpio split the file it is to large to fit on a floppy? What about the files I have on the disc right now. I was using dos formated floppies and then ran tar to do the copy. Is it possible that I can read them using some of the suggested way?

I can't answer your question, but I would like to suggest an alternative that might be less work. Use cpio to make on output file and compress it onto floppy using the compress command, which I have checked also exists on CentOS (I *presume that your old UNIX doesn't have {b,g}zip. I see a reference also to pack, but it seems to be only man pages. Both of these compressions programs are very old and should be on your system.
For cpio, which does work well on SCO:
cd path_to_directory find . | cpio -ocv | compress > /dev/rfd0135ds18
and then to extract under Centos:
cd path_to_where_you_want_to_extract gunzip < /dev/floppy | cpio -idmvc
BTW, I don't think that multivolume archives work between SCO and Linux for either cpio or tar. They might work for cpio, but definitely not with compression.
If it works and you need multivolume, you'd have to do:
find . | cpio -ocv -O/dev/rfd0135ds18
Also note (FWIW) that SCO's tar will silently fail to back up empty directories and will not backup device files.
