Masterminds of Programming
This book features exclusive interviews with the creators of several historic and highly influential programming languages. In this unique collection, you'll learn about the processes that led to specific design decisions, including the goals they had in mind, the trade-offs they had to make, and how their experiences have left an impact on programming today. It includes individual interviews with: Adin D. Falkoff: APL ; Thomas E. Kurtz: BASIC ; Charles H. Moore: FORTH ; Robin Milner: ML ; Donald D. Chamberlin: SQL; Alfred Aho, Peter Weinberger, and Brian Kernighan: AWK ; Charles Geschke and John Warnock: PostScript ; Bjarne Stroustrup: C++ ; Bertrand Meyer: Eiffel ; Brad Cox and Tom Love: Objective-C : Larry Wall: Perl ; Simon Peyton Jones, Paul Hudak, Philip Wadler, and John Hughes: Haskell ; Guido van Rossum: Python ; Luiz Henrique de Figueiredo and Roberto Ierusalimschy: Lua ; James Gosling: Java ; Grady Booch, Ivar Jacobson, and James Rumbaugh: UML ; Anders Hejlsberg: Delphi inventor and lead developer of C#.

Real Time Forth - reprinted as ebook
Tim Hendtlass, the author of Real Time Forth, obtained a PhD in Ionospheric Physics in 1974 working at Massey University, New Zealand, and then worked at RMIT and Swinburne University of Technology, both in Melbourne, Australia where he currently resides. ...
The book Real Time Forth was written in 1993, and contains a vast amount of Forth code to go through and understand; and this gem has now been saved and made available as part of the Forth Bookshelf at https://www.amazon.co.uk/Juergen-Pintaske/e/B00N8HVEZM .
The book is based on F-PC, a DOS based Forth, which was very much in use at the time ... take a look at http://www.forth.org/eforth.html, you find Public Domain Forths there, F-PC and Tings F-PC tutorials.

VCFe
Zum achtzehnten Mal kommt das Vintage Computerfestival Europe am Wochenende vom 29. April bis zum 1. Mai 2017 nach München. Ziel des Vintage Computer Festivals ist es den Erhalt und die Pflege 'historischer' Computer und anderer (E)DV Gerätschaften zu fördern, das Interesse in 'überflüssiger' Hard- und Software zu wecken und vor allem den Spaß daran auszuleben. Das VCF ist nicht nur im kalifornischen Silicon Valley ein regelmäßiges Ereignis sondern inzwischen auch ein fixer Punkt in den europäischen Terminplänen. Also lasst uns zurückkehren in die Guten Alten Tage, als Hacker noch keine Sicherheitsberater, Bytes noch keine Megabytes und Kleine Grüne Männchen noch Kleine Gruene Maennchen waren!
Forth wird dort auch zu finden sein. Carsten stellt seinen AMITARI aus, ein Amiga 600 mit Atari ST EmuTos. Dort laeuft auch das VolksForth in der Atari ST Version. Und den Forth-Benchmark-Wettbewerb gibt es auch wieder.

Announcing release $40 of amforth
This is the 64th release of amforth in more than 10 years development. It does some fine-tuning of the I2C library on the AVR platform. There is now code to use amforth as a I2C slave. Furthermore it adds the 'c' number input format and support for program specific stacks. "under the hood" are many small improvements and code simplifications. A lot of previously hidden words or words that were intended for testing purposes only are now available for user programs. Atmforth is a 16bit Forth system designed to run on AVR Atmega and TI MSP430 microcontrollers. It is written in highly optimized assembly and Forth itself, most of the core system shares the same source code. The core system fits into 8KB of code space. It allows access to all controller specific features including support for Harvard architecture specific things like multiple address spaces of memory (EEPROM, flash, RAM). The Forth interpreter compiles directly into the flash (or FRAM) memory. Amforth supports most features of the Forth 2012 standard and has a few enhancements over it like recognizers.
Amforth is released under the Terms of the Gnu Public License v3 (GPL) and is available with full source code and documentation at: http://amforth.sourceforge.net/

Forth für die JVM
Ich bastele gerade an einem Forth-Interpreter, den ich hier fand: http://linuxenvy.com/bprentice/JForth/ Bisher habe ich ihn um das Rechnen mit komplexen Zahlen erweitert.
Beispiel:
1+2i 3-5i * . 13.0+1.0i OK
^^ multipliziert zwei komplexe Zahlen und gibt sie aus.
Das ganze soll im Endstadium eine Art Forth-programmierbarer Desktop-Rechner werden. Eventuell mache ich auch eine Version für Android dazu. Als nächstes kommt das Rechnen mit Brüchen rein, ein spezieller Datentyp und automatisches Kürzen, finden von ggT, kgV usw. Das Projekt ist hier: https://github.com/nietoperz809/JForth/tree/master/JForth_jar Im Verzeichnis JForth_jar ist eine ausführbare Datei, falls man nicht compilieren möchte. Java muss installiert sein, wenn man die Datei starten will. Ich freue mich auf Anregungen ... -> pitti

Easy Forth
Nick Morgan hat eine wunderbare Einführung in Forth erstellt. In Javascript. Man kann sofort im Browser loslegen - wunderbar. Folgende Kapitel werden bereits geboten: Introduction, Adding Some Numbers, Defining Words, Stack Manipulation, Generating Output, Conditionals and Loops, Variables and Constants, Arrays, Keyboard Input und ein kleines Spiel - Snake!

noForth version 170222 is ready ...
It supports the new large (256kByte) FRAM boards. Also it supports the MPU (Memory Protection Unit) onboard this FRAM chips. All supported FRAM chips now have this feature, it protects the kernel from writing to erroneous addresses, without disabling compiling and patching!
Kind regards, Willem Ouwerkerk.

eForth and Zen - 3rd Edition 2017 - Kindle Edition
by Dr. Chen-Hanson Ting (Author), Juergen Pintaske (Editor).
eForth has a long history, but here in this eBook you see it updated, and the 2017 edition 3 includes ports that are recent, and all of the sources are available to order, check and use - directly from Ting. It is important to have this whole range of eForth variants available, as this eForth range of implementations includes as well so called Soft Cores, which are microprocessors, targeted at Programmable devices called FPGAs. Here, a standard version supplied separately can be used in projects and in addition to the processor core the complete eForth language to drive this chip is supplied. In addition, the Core can be modified, and the modifications can be controlled by extensions of the supplied eForth software - complete flexibility to adapt SW and HW to the design.

Footsteps In An Empty Valley - Kindle Edition
Jürgen hat Chen-Hanson Ting so lange bearbeitet, bis dieser seinen Klassiker davor gerettet hat auf nimmer wiedersehen in der Altpapiertonne zu verschwinden. Digitalisiert gibt es das Buch also nun wieder, auch bei Amazon als eBook.
"Chuck Moore is the inventor of the High Level computer Language Forth. In this eBook you find the background, how and why it was designed as is. People talk about C friendly instruction sets and processor architectures - but Chuck went one level further and implemented complete functionality in silicon long before others looked at such configurations. And there is the Forth code from then, designed by Chuck and a lot of typing in by Ting."
