Little Smalltalk
Little Smalltalk is a non-standard dialect of the Smalltalk programming language invented by Timothy Budd. It was originally described in the book: "A Little Smalltalk", Timothy Budd, Addison-Wesley, 1987, ISBN 0-201-10698-1.
The Little Smalltalk system was the first Smalltalk interpreter produced outside of Xerox PARC. Although it lacked many of the features of the original Smalltalk-80 system, it helped popularize the ideas of object-oriented programming, virtual machines, and bytecode interpreters. Timothy Budd later rewrote Little Smalltalk in Java, and distributes it as the SmallWorld system.
