The Smalltalk-76 Programming System - My original paper on Smalltalk-76. Describes the syntax. object model, and design of the byte-coded virtual machine. Includes a sketch of the vm written in Smalltalk-76 itself. Back to the Future: the Story of Squeak - Describes the design of Squeak, a commercial-grade Smalltalk written in itself and made practical by compiling a subset of the language ("Slang") to C. The Evolution of Smalltalk from Smalltalk-72 through Squeak - A long paper (100 pages!) that I wrote for HOPL-2020. This version includes corrections, and is a mixture of stories, technical details, and links to simulations and related work.
