When did Windows start accepting forward slash as a path separator?

Yup.  I should have copy&pasted rather than just type it in.
It should have been in quotes.  The following does work for me

E:\dalke>cd ..

E:\>cd /dalke
The system cannot find the path specified.

E:\>cd ./dalke

E:\>cd "./dalke"

E:\dalke>ver

Windows NT Version 4.0

E:\dalke>
