The Sierra Network / ImagiNation versions

[OmerMor]

Hi,
I'm trying to find information about the different versions of TSN / INN and where to find them.
I found the following versions:

• v2.1: 03/1993 - from EcoQuest 1 CD
• v2.3: 02/1994 - from Phantasmagoria 1 CD
• v2.4: 05/1995 - from the InnRevival project

Can someone tell me about other versions they know of, and where they can be found?
