Star Wars Trilogy (Alternate)

Hello there !

I don't even remember how I found this, but I recently learnt that there was an "alternate" sequel trilogy:

• Episode VII: Heir to the Empire (1993)
• Episode VIII: Dark Force Rising (1995)
• Episode IX: The Last Command (1997)

I don't seem to be able to find any copy (in any format).

How is this a secret so well kept ? But more importantly: how can I put a hand on this ?!
