TSF had several releases over time. In chronological order (I hope):
- original Project 2 release (black interior, includes JJ2)
- Polish Avalon release (... polish, duh!)
- Project 2 rerelease (cardboard frame interior, includes JJ2)
- German Hemming rerelease (cd-case)
- NCI Dotcom rerelease (cardboard box, includes JJ2)

From the top of my head those are all the official releases of TSF. You can find several up for sale from time to time on eBay, mostly the German Hemming release or the NCI Dotcom rerelease.
