"Kevo is a prototype-based object-oriented system build around a very simple object model. Unlike most object-oriented systems, Kevo does not have classes. And unlike the few other prototype-based object-oriented systems (such as Self), Kevo does not feature delegation. Instead of classes and delegation, Kevo is based on concatenation: unrestricted composition of object interfaces. In concatenation, objects are derived from each other simply by cloning (copying) and subsequently modifying them so as to differentiate them from each other. The system automatically maintains information about clone families (groups of similar objects) and their derivation relationships."
"Mops is an object-oriented programming system, derived from the Neon language developed by Charles Duff and sold by Kriya, Inc. Kriya have discontinued support for Neon, and have released all the source code into the public domain, retaining only the ownership of the name Neon.
Mops is a complete re-implementation of Neon, with many additional enhancements. It is also in the public domain."
"Forth is a beautiful language. It is easily spoken and source code looks like poetry. Oh yes, Forth produces fast compact code. Pocket Forth is a small Forth system for the Macintosh computer, founded on well documented principals. Although Forth is being standardized, Pocket Forth has evolved independently of the standard.
Pocket Forth is based on Flint by G. Yates Fletcher, figFORTH and the Forth described in Starting FORTH by Leo Brodie. I wrote Pocket Forth to experiment with the Macintosh toolbox and Apple Events. Pocket Forth can produce applications that run under any system version."

"MacQForth is a version of the Forth programming language. Its
primary purpose is to teach Forth to beginning Forth programmers. QForth itself was written for the Apple IIe by Toshiyasu Morita and is run on the Mac by a 65C02 microprocessor simulator. For the most part, the code is identical to the Apple II version."
"Yerk is an object oriented language based on a Forth Kernel with some major modifications. It was originally known as Neon, developed and sold as a product by Kriya Systems from 1985 to 1989. Several of us at The University of Chicago have maintained Yerk since its demise as a product."
