For all those of you who don't know what CP/M is, it is the first operating system ever made for micro computers. It evolved into 86-DOS and finaly PC-DOS and MS-DOS. I found a neat web site all about it, ceck it out at http://museum.sysun.com/museum/cpm.html they even have a system set up with CP/M that you can telnet into.

telnet dino.sysun.com 4006

that should log you into the system and you can try it out. The first version of CP/M suported the 8080 microprosseor. The fascinateing thing is that the person who developed it did not have a 8080 microprocessor to test it on, after the development was complete, he found someone who was willing to conect his floppy drive to their 8080 to test the system out, it worked without a problem first time.
