OS/400.

If you are curious, have a peek at the green screens at Costco, Canadian Tire.

I worked 30 years with that OS, the last 10 as SysAdmin. Never hacked, never crashed.

Microsoft Basic not an OS,  Here some MS-DOS, Reactos (reverse engineered of Windows NT Kernel, can run some windows programs),  Atari TOS, MiNT, AmigaOS (still in support, can run on Raspberry Pi, really cool), RISC OS (running well on Raspberry Pi), Haiku OS, Singularity (Microsoft Prototype OS made in C#)
