This was one of my favorite games/interactive novels. I now have an Apple II emulator for my Mac, and ROMs for other games I owned in the past, but I just can’t find the ROMs for this thing (granted, there were like 6 disks…). Has anyone ever come across it? A search is painful as searching for the word “portal” on the web turns up a kajillion hits.
There is (or was) a Mac version of Portal as well, so you might also want to look for that. The only version I can find at the moment is the PC version (and I will refrain from linking to it out of respect for the copyright issues involved).
The author of Portal has an on-line version of the novel based on the game here. The site may also have a source for what you are looking for.
Wow. That on-line link is freaking amazing. Thank you so much.
