Just Useless & Needs Killing?

Or CP/M?

Command Processor for Microcomputers?

CP/M is where DOS came from, and it was the first "universal" operating system for desktops. Spreadsheets, Word Processors, Machine Controllers, and many other apps we use daily were available for CP/M, and you could buy a CP/M app and it would usually run on any machine with CP/M. DOS wasn't the spark that lit the desktop generation, CP/M was. There were even CP/M expansion cards for Apple II's. You might recognize the MFR... MicroSoft based in New Mexico.

I have 4 working CP/M machines, three are machine controllers, 1 is a Xerox 820? All with 8" 1.2mb Floppy Drives. The last of them were retired a couple months ago. The Xerox sold for about $10k new with 65535 bytes of RAM and a 8085 processor @ ~2mhz.

I also have an original DOS 80486DX-33 machine that ran for about 20 years every day.
