CP/M is really open-source now
I remember, when I was a kid, having a CP/M diskette for the Amstrad CPC. It was provided with the machine. Every now and then I would try it out, not really understanding what it was about.<p>Years later I learned, reading about it, that it was some sort of "professional" OS on which productivity software would be used.<p>Does anyone actually used that OS on CPC or any other 8bits machine of the 80s to do anything remotely useful? Genuinely interested.
