##CP/M: The original OS for Intel processors

This subreddit is about CP/M, MP/M, FUZIX, and other 8080/Z80 operating systems.

How to start with CP/M

Rules:

"Wanted" posts and free items for pickup are ok (as text/self posts, include your location & [Wanted] or [Free] in title), but "for sale" posts, ebay links, or "what's this stuff worth" posts are not. No you didn't just find a pot of gold or win the lottery, and if you did, there's better places for that.

If you're asking a question you need to make a "self" or text post. Feel free to ask for help with where to get CP/M for a specific machine, how to run a Z80 emulator, how to do troubleshooting and repair, what was the name of that amazing flight simulator you played on the TRS-80 Model II, etc.
