Oh yes!
I use an ancient ms-dos program called Telemagic.
Originally designed to be contact management software for telemarketing companies, it prints work orders, records everything we do. It allows me to schedule callbacks, work to be done, etc. Pretty much anything I can think of, it will do. It's even network software, so I could hook up any number of other terminals, all of us working on the same database.
Unfortunately, the software never graduated to microsoft windows, and it is getting very tricky to keep it running.
Modern software that pretty much duplicates it's functions are ACT or Goldmine. There are probably an army of other programs like these that I am not familiar with.
