SDK for Windows 1.04??

        Well, Win104 did not have DLLs, but it did have *.DRV drivers. The
balance of Windows was implemented as an overlay file (win100.bin) which has
a standard NE-style format. So, conventional Windows spleunking tools work.

     I don't think Windows 1.04 had DLLs! It ran in real mode and used
simple .EXE files as programs and nothing else.

This is all pre-DLL days. Richard is referring to

in the DLL. Not all functions in a dll have their names exported and
sometimes the only way to get to them is by ordinal

by utilizing these undocumented calls.
