Thanks tompe and HarryT, I'm glad I didn't have to defend IF all alone
I took a look at "Alice..." that's sort of what I was talking about, I would definitively love to play Zork on the PRS-700 though I think its commands are a bit too complex to be done properly via the way illustrated in that Ebook.
I did a few google searches to see if I was able to found the Zork text in PDF and maybe sort it out alas I was not lucky enough. HarryT since you are familiar with Z-machine, can you tell me how it stores its text and choice branches?
