I got a copy of The Newsroom by Springboard new in the

ago. It's for the IBM PC and came on two 360k 5.25" floppies.
The first thing I tried to do was make copies of the disks.
Unfortunately it's protected and so I'm not exactly sure how to back
them up. I tried teledisk but the copy it made doesn't work and
Newsroom keeps insisting that I insert the original disk when I try
using it on my PC.
I read that teledisk was supposed to be able to deal with copy
protection, but it clearly doesn't. I don't have a kryoflux. What
other options are there for making backups of protected disks?
I'll say it once and for all: Teledisk was never intended for making copies
of copy-protected floppies. Never. It was developed as a way for people to
send non-standard (i.e. not DOS) formats around.
Originally developed as a companion to 22Disk and Anadisk.
Copywrite was one package for circumventing copy protection and used various
methods, including code patching to defeat copy protection.
CopyIIPC was another and optionally used a special card to accomplish its
task.
There are many, many forms of copy protection, including physical
modification (e.g. laser burned hole) of the medium. Ultimately, any form
of copy protection can be defeated by modifying the application itself.
