SYMBOLICS CONCORDIA ONLINE DOCUMENTATION HYPER TEXT MARKUP 1985
4K views · 13 years ago · demo · intermediate · historical
A 1985 demonstration of Concordia, the hypertext documentation and markup system on Symbolics Lisp machines. It shows documents with links, formatted text and graphics in a windowed interface, long before the web.
HN lists it among the classic GUI demos worth watching to get a feel for early interface ideas, and as proof that Lisp-machine teams built large, polished documentation tools.
