Abase is an early 1970s text-based computer game for BASIC designed by People's Computer Company similar to the game Number. In the game Abase, one chooses a base from 2 to 10 and guesses a number the computer has chosen in that base. The game appeared on page 4 of the book What to Do After You Hit Return or P.C.C.'s First Book of Computer Games.
