That was fun. Useless, but fun. I haven't seen #MS-DOS 4.0 since I borrowed my uncle's laptop (with a grayscale LCD, so this is the first time I see DOSSHELL in colour!)
I got inspired by #Microsoft releasing the MS-DOS 4.0 source code - https://www.theregister.com/2024/04/26/ms_dos_4_open_source/ - of course they didn't release the installer, the #DOSSHELL nor localized versions, so the install disks were obtained elsewhere...
Reminds me of the old quote "DOSSHELL? Of course DOS is hell"
