Ancient operating systems
Consider trying an older Linux distribution or a Unix-like system such as Ubuntu, Kali Linux, or even SUSE Linux Enterprise. These options offer a rich exploration of legacy OS features without being tied to Windows post-2000.
Linux and BSD both existed before the year 2000. If you're seeking an older release of either, BSD could be a suitable option.
I’m not familiar with many operating systems before the year 2000, but BeOS could be worth exploring. AmigaOS might also be an option if you locate an older release.
OS 2/WARP might offer some appeal. On the home PC market, I believe most mainstream machines relied on DOS until Windows appeared—initially as an interface atop DOS, and in certain cases even retaining DOS under Windows 9x (like WinME). If you're looking further back, CP/M could have been relevant.
Couldn't install DOS 6.22 on the HDD, but I did get MS-DOS 7.1 dual-booted and tried Windows 3.1—it was really frustrating. Even after adjusting system.ini, it kept showing an issue with a value like PageOverlay, saying it should be under 4, but the file isn't in the Windows 3.1 installation directory. I have w3xstart.exe there, but it also fails. If you have a Windows 3.1 ISO, that might work and would be really helpful. Thanks!
