Searchable Stanford Campus
There is open parking on
weekends. Park in any A or C or metered space.
Take the elevator to the 5th
floor. Walk across the foyer and up the ramp just to the left of the glassed-in
office. Room 556 is at the top of the ramp - entrance on the left.
Wireless Internet access is
anticipated (though not guaranteed) at Stanford, so bring your wi-fi enabled

Meeting Agenda to: George
Donate your Forth books -
"If anyone has Forth books they no longer need, please
donate them to me for the Noisebridge hacker space where I teach a Forth class.
Bring them to Forth Day."

Meeting Agenda for Forth Day
08:30 --- Coffee and a Chat
09:00 --- Welcome - George
George, the SVFIG Chairman, will offer a few words of welcome and
include some announcements about books and t-shirts.
09:10 --- eForth in C - CH
This the by far the simplest Forth ever written in C. Existing
versions of Forth in C were all complicated because of C language requirements
and the underlying operating system limitations. This implementation is based
on a very simple Forth Virtual Machine written in C, which executes Forth words
in a dictionary. This dictionary is constructed by an eForth metacompiler and
inserted into a byte memory array in C. The Forth Machine can be quite simple,
with as few as 31 primitives, or can be optimized to have 256
09:40 --- PACE FIG-Forth - David
David Kilbridge was the implementer of the original FIG-Forth
model for the PACE processor. He will provide a little insight into this
processor and his implementation of the
FIG model on it
in the early days of the Forth Interest Group.
10:00 --- Resurrecting FIG-Forth through
Simulation - Eric Smith
Eric will give a brief review of his work
porting PACE FIG-Forth to his simulated
IMP-16 and eventually to real
hardware. He'll then describe the progress he's made since
10:15 --- Overview of the Forth Foundation
Library - John E. Harbold
John will discuss code which makes use
of the Forth equivalent of a C++ Class Library. The
Forth Foundation Library (FFL) is a
general purpose Forth library whose main purpose is to make it easier to
develop applications. Examples include a Finite State Machine (FSM) and Dynamic

10:30 --- Break
10:40 --- Cheap, Simple, and
Functional - Bob Nash
Using inexpensive hardware and free
development tools, professional-quality, high-performance instrumentation can
be designed quickly. This presentation will describe several of these
development environments and show instruments that have been built with
11:10 --- Icon Forth - Brad
A picture is said to be worth a thousand words. Icon Forth
replaces traditional Forth words with images and the dictionary is a
collaboratively edited online database.
11:40 --- Discussion of a Native Forth for
a NetBook - Sandy Bumgarner
"Wouldn't it be wonderful to have a
cute, inexpensive, and complete computer that runs only Forth? Ah, nothing but
you, Forth, and the hardware! Such a system could be built with an
ASUS Eee PC and
perhaps other netbooks. Let's talk about it ..."
12:10 --- A Moment of Remembrance and
Celebration for Dave Boulton - Sandy Bumgarner and Cousin
12:30 --- Lunch in Gibbons Grove -
Catered by CH Ting
Adjacent to Terman Engineering Center
13:30 --- Forth System on a Programmable
Chip - Leon Wagner
"I will build a
System on a Programmable Chip (SOPC) design in the Altera Quartus II
environment, program the design into a Cyclone III FPGA, and then interactively
develop some Forth code to run on the newly instantiated core."
CFV1CORE_ALTERA, available free of charge from IPextreme, is the same V1
ColdFire processor core implemented in Freescale's MCF51QExx devices, but
delivered as an SOPC Builder design optimized for the Altera Cyclone III FPGA.
The V1 ColdFire system bus has been adapted to the Altera Avalon system
interface for the CFV1CORE_ALTERA implementation."
Cyclone III Starter Kit (used in demo)
14:30 --- Venture Forth Toys -
Dennis A. Ruffer
"While working at the IntellaSys Radio and RF
division in Colorado, I came up with some plug-ins for their VentureForth
compiler. I will give a brief introduction to them and explain why I found them
to be useful."
- VentureForth Compiler
15:00 --- Break
15:10 --- IntellaSys Hearing Aid
Project - Michael Montvelishsky
The bleeding edge of hearing aid
technology is arcane and counter-intuitive. Michael will pull back the curtain
and reveal the secrets behind the DSP black magic. This may be the most
remarkable real-world application of the IntellaSys SeaForth
15:50 --- New Code on the New Hardware
- Jeff Fox
Jeff will give a live interactive demonstration of the
colorForth tethered IDE as well as take up topics from his
blog and show off this
16:30 --- Square Root Routine for the c18
(s40 CPU) - John Rible
John will discuss his colorforth
implementation of a 32-bit square root routine for the c18 (s40 cpu) and talk
about the eForth interface he used to test it.
17:00 --- Fireside Chat -
18:00 --- Adjourn
18:20 --- Dinner Banquet
1039 El Camino Real

WAV File and Soundcard I/O Software
Using Win32Forth - Andy Korsak
This software was written for
amateur radio applications. Andy has suggested that it might be useful to look
at his code in advance of his talk. Contributions to this work-in-progress
would be welcomed. You can download and view his sound card software on the
group (membership required), or here.
Solicitations for presentations and
Mitch Bradley's Forth in C
volunteer is needed to present and demonstrate this software.
PowerMops Forth for the Mac -
Kevin Appert: "Mops
is an open-source, full-featured, object-oriented stand-alone programming
language for Mac OS X descended from the much-beloved NEON. I now have a
working installation and when I know enough to do a good demo, Ill be
doing a talk. Id be grateful for any help and advice from anyone familiar

Carbon Mac Forth - Kevin
Kevin Appert: "Mac Forth
was the first programming language used on the bench to bring up the Mac and
the first programming language with Mac API available to the public. I have
substantial interest in the current version, Carbon Mac Forth and Im
hoping to do what I can to promote it. I'm unable to contact Ward McFarland,
the Carbon MacForth guy. If anybody knows a good way to buy a copy, please fill
me in! His email appears full and he doesn't reply. The phone number is out of
service, but the website is still up. Im hoping that if Carbon Mac Forth
is now an orphan, we can make all the source and executable available on our
