There is a wealth of online information about Forth. This page catalogs just a few of the sites some of our customers have found to be useful.
FIG is the world's largest and oldest organization supporting Forth programmers and the Forth language. It is a non-profit group that specializes in providing both reference and tutorial materials, a superb magazine, software, conferences, local chapter meetings, and professional contacts within the industry.
Information about ANS Forth is available at this site, which includes electronic copies of the last draft version of the standard, and lines of communication with the Technical Committee that developed the standard and which issues clarifications about it.
Open Firmware (also, OpenBoot) is a hardware-independent firmware, developed by Mitch Bradley at Sun Microsystems, and used in post-NuBus PowerPC-based Apple Macintosh computers, Sun Microsystems SPARC based workstations and servers, IBM POWER systems, Pegasos systems, and the laptop designed by OLPC among others. It is available under a BSD license. Open Firmware is accessed via a Forth-based shell interface and fulfills many of the same tasks as BIOS does on PC computers, although Open Firmware is considerably more powerful than BIOS.
The Forth Scientific Library project develops and referees Forth code of particular value in scientific applications. The team is implementing, for example, the ACM libraries, BLAS, LINPACK, etc.
The euroFORTH Conference is the preeminent Forth gathering outside the U.S.A. It is held each year in a European venue that provides an attractive backdrop to the technically sophisticated, socially relaxed meeting.
Space-Related Applications of Forth

Space-Related Applications of Forth are documented in a table of impressive projects at this site maintained at NASA's Goddard Space Flight Center.
