    for us in the 1980s we had dos 4 on a shelf and stuck with dos 3.3.

    we sold accounting software and it took a lot of conventional memory. 484k or so iirc. when you used dos 4.

    * we loaded a keyboard driver for uk/irish keyboards. otherwise we'd have no £ for documents.

    * share.exe for file locking

    * ipx for novell networking

    * driver for network card.

    on dos 4 that usually left us about 4k short to run the accounting software. we had to wait till dos 5 came to move past dos 3.3
