Interesting note, a lot of these tapes have hundreds of 0-length files
on them; these seem to be placed between files with actual data in
them. I have no idea if this was a standard practice (maybe
ComputerVision hadn't heard of "tar" :)).

What you are seeing are file marks, which will return a zero length file if
you just 'dd' them. I haven't looked at CV tapes in a LONG time, but from
memory they are modified SunOS 3 - 4 distributions. What you should find is
a table of contents at the front, some stand-alone utils, a dump file of the
system, and lots of tarballs for the optional parts of the system.
