If you are referring to the old CD-ROM’s that Jaguar was providing more than 10-15 years ago, which require Windows 2000 (no, they won’t work even on XP), then, I am afraid you are stuck with vintage PC.
I have one of them. If you actually “explore” the disk contents, you will see that each section is already a PDF. AdobeReader will read it and it can probably be transferred.
The problem is that the software that Jaguar uses to browse the contents and let you search is not amenable to any of the tricks mentioned earlier in this topic. Somehow, even though it is a rather primitive program, it won’t run if you change the operating system, try to create a disk image, and/or try to make a copy of the CD.
It only works from the original CD and only under Windows 2000 that runs native. I had tried it on a Mac that had a VirtualPC with Windows 2000, but the disk could not be used as intended.
After many years, I’ve given up oil the idea to transfer the contents.
There is a long thread on the V12 sub-forum, where a copy of all PDFs, bundled together is a single PDF can be obtained.
This 1000+ page PDF is not searchable, obviously, but all sections are in order.
That PDF can be read on any platform.
