Will WinBoard run on Windows 3.1? How about Windows CE (also known as Pocket PC)?
WinBoard does not run on Windows 3.1, Windows for Workgroups 3.11, etc., not even with the Win32s compatibility package. The main problem is that Win32s does not have threads or real concurrent processes. A port of WinBoard to Windows 3.1 is possible in theory, but it would be difficult and messy, and no one is going to do it. WinBoard does not run on Windows CE (also known as Pocket PC). I don’t know what would be required to port it. WinBoard does run well on full 32-bit versions of Windows, such as Windows 95, 98, NT, 2000, ME, and XP, and should continue to work on future 32-bit Windows systems.
