An ODT 3.0 CD doesn't contain a mountable filesystem.  It contains a
series of tar archives separated by "file marks".  Under SCO Unix /
OpenServer, this format can be accessed via the "cdt" (CD Tape) driver.
But you should be able to read it on any system by using `tar`.  Just
plain `tar tvf /dev/cd0` should show the contents of the first archive.
To get to the next archive you'll have to figure out its offset and use
something like `dd` to grab it.

OpenServer CDs didn't switch to an ISO filesystem format until OSR5.0.0.

Also, inside the tar archive, most of the files within the will be
compressed.  There's an archive header bit that says which files are
compressed, which bit will probably only be recognized by SCO Unix /
OpenServer `tar`.  Basically if a file has a name other than "*.Z", but
shows up as LZH-compressed, you need to rename it *.Z and uncompress it.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
