Rosetta Smalltalk is a personal information handling environment for low-cost microcomputers based on the work of the Learning Research Group at Xerox PARC. Our prototype runs on two different Z-80 based personal computers. The major goals of the system are to support a lively interactive style of working and to provide an open-ended medium in which personalized tools may easily be constructed. Rather than write monolithic programs, the user extends the language with new objects and syntax. He…

Managing graphical resources

Although it is possible to write device-independent interactive applications using mainstream techniques, the quality of the user interface may vary wildly as they are ported because of the mainstream's lack of the mechanisms needed to control the allocation of real graphical resources within the application.

Personal Dynamic Media

The Learning Research Group at Xerox Palo Alto Research Center is concerned with all aspects of the communication and manipulation of knowledge and has designed and built a communications system: the Smalltalk language, implemented on small computers they refer to as "interim Dynabooks".

The paper summarazes the LISP style of interactive programming for readers outside the LisP community, describes those propertms of LisP systems that were essential for the development of this style, and discusses some current and not yet resolved issues.

The Smalltalk-76 programming system design and implementation

This paper describes a programming system based on the metaphor of communicating objects which provides flexibility, modularity and compactness, and a corresponding virtual memory is described which offers dense utilization of resident space.

Programming with abstract data types

An approach which allows the set of built-in abstractions to be augmented when the need for a new data abstraction is discovered and is an outgrowth of work on designing a language for structured programming.
