Why Would You Want CP/M+?

The first time I knew that CP/M was available to us via the AERCO disk system and the ZEBRA FDD 3000, I wondered what version of CP/M it was. I soon found out it was CP/M 2.2. 1 spoke with Ron Lane, SYSOP of the FWKUG MBBS & PSDE, and he told me that as long as it was CP/M 2.2 or better, we could use almost any CP/M program that was downloadable on his BBS. I needed to know more about CP/M, so I looked at a book on CP/M that I had purchased years earlier. It was some help, but not much. When I received my disk system I purchased another book, the CP/M BIBLE, which was a great deal of help. I noted in these two books some version of CP/M called version 3.x or CP/M+, I thought that, so long as we were able to use CP/M, why not get the most current version instead of 2.2. 1 soon found out that CP/M+ was great, but, for me, CP/M 2.2 was better. I found some information that just might let you know what I am talking about.
