Is it possible to install CP/M on a 486 computer ?
I don’t even know where to get CP/M but it sounds intriguing.
I would like to install it on my IBM 486 PS/1 computer.
Is this possible ?
CP/M-86 was created long before 486s were commonplace, and will likely have timing issues and other problems on such a fast system. Try it with a 8086-based system.
CP/M-80 and other versions won't run at all, because they are for the wrong system architecture.
You could perhaps also look at Concurrent DOS 386, if you feel like tinkering around with it.
Or try a emulator for a Amstrad CPC or other 1980s gaming system that ran CP/M.
You have to keep in mind that it's a very primitive DOS-like system with slightly different commands and basically no graphical user interface similar to the more advanced version of Windows (3.0 and higher) available. Many applications were monochrome, and mouse and other peripheral support was often dependent on the application via integrated drivers.
I've used it on a Amstrad PCW Joyce word processor - on that Zilog Z-80-based system Locoscript (especially version 2) was a quite a bit more advanced user experience than raw CP/M-80 (and it still has features absent from modern word processors 😲 ).
If your aim is purely to experience a Digital Research OS, then may I suggest DOS Plus or DR DOS? The latter has more recent versions available.
Furthermore, if you want to experience a early graphical interface, try GEM, which also has fairly recent versions.

Yes. There was a modified copy of CP/M-86 with 1.44MB floppy drive support and RTC(AT) support.
It's described at http://www.gaby.de/ecpm86.htm

I hope nobody feels offended by me posting these links.
CP/M has become some kind of open source in the last fear years.

You could also install DOS Plus or DR-DOS, the successors to CP/M-86.
or under dos, run 22nice, the z80 cpm emulator.

Or run CP/M-80 programs through Z80.CMD via CPM.EXE on DOS Plus. 😎
