I have just gotten about 80 RK05 disk packs for a PDP-11. They have been stored in an office environment, but most have not been used for at least 15 years. Some have labels indicating they were cleaned by SCOPUS in the late '80s. Any recommendations on the best way to store them would be helpful. If anybody is interested in some of them, they can be had for the shipping. Contact me offline if you are interested and we can talk about the details. I am located in Ohio, USA 45865.
