@realman543 @longyap @iska @mint @m0xee Acceptable operating systems: Plan 9, ANTS, 9front, 9legacy, Inferno, DIY Forth environment, CollapseOS, DuskOS, boot sector demos, MS-DOS 5.0 (but only to run for exactly as long as needed to bootstrap your DIY Forth environment), or a ROM-based OS that came with a 1980s-ass computer. The list is complete. NT4 is not on it. Smalltalk? AmigaOS? Meego? No, no, no. ReactOS? Minix3? Minix*2*? You fucking kidding me?
