Companion to the excellent "Smalltalk-80 : The Language and Its Implementation" by Goldberg and Robson, it's a guide to a past time, when rich programming environments existed for the more sophisticated languages. Remember, when this was written, most computer systems didn't have a mouse, nor any concept of one. Interactive computing was just getting a start, and many systems were still programmed with punched card decks (and some even with paper tape).

It was an excellent book for that system. It seems archaic now, and yet I'd still like to have that environment to program in. ( )
