@jynx If the only requirement is a hypertext-like environment in the Unix terminal, then you might try Lynx. But if you actually want to run old Hypercard stacks then I think emulation is the only way.
@tomte So many wiki-like things are available on the terminal, lynx being semi-related... Hypercard was of course so much more. I can envision something similar living in plaintext, maybe in a canvas provided by curses. I am afraid this vision is much larger than my abilities to code!
