The hint system was just an in-game implementation of the InvisiClues that they used to make. The electronic implementation was introduced in the Solid Gold line of discount repricings of the big classic games without feelies and such. (H2G2, Planetfall, Zork I, Wishbringer, and Leather Goddesses of Phobos were the series.)
Later on, they added it to a couple of first releases as well - I know that Nord and Bert Couldn't Make Head nor Tail of it had it as well.
