   To my
knowledge the Linux kernel was released to the public 30 years ago
 around this time. My dear friend swears by it and will never go back to
 Windows even though WIN 11 is much more secure than previous Windows
 versions. Prior to Linux there were other much-earlier operating systems
 for 8-bit and 16-bit machines we classic computer users could use. For
 emulators now we have a choice but do they work better in Linux or
 Windows?  Murray  ?
