Does anyone of you have somwhere in your archives older versions of Apple's "Network Software Installers"?

Apple has only versions 1.4.4 and up on their servers (and numerous mirrors), but I am looking for complete installers of:

1.4

1.4.1

1.4.2

1.4.3

There are some older NSI's around that were included in various "AppleShare" installs, but they are incomplete and have some driver resources removed :-(

They're also called differently, namely, Network Software Installer ZM-1.3,... ZM-1.4 etc.

I'm doing a bit of a research on FDDI implementation and would like to check older NSI versions. Any help will be very much appreciated!

Cheers,
