Introductions, Announcements, Rumors, and Gossip

CH Ting - New Actel FPGA Board with eP32
This board has an Actel APA150 FPGA chip, 4 MB of flash, 256 KB of SRAM, and a host of IO devices. It includes all the VHDL code and the eForth source code and is useful for experimenting with a 32 bit eForth system. Five board sets are available for $300 each.

Tim Duncan - Digital Music using Forth
Tim will give a brief update on the low-level audio words.

LaFarr Stuart - An Experiment in Stack Oriented Variable Precision Arithmetic
Lafarr will demonstrate the advantages and disadvantages of single character arithmetic operators and input/output conversion in various number bases for very large numbers (50 thousand digits).

Lunch - BBQ lunch sponsored by CH Ting

Kevin Appert - Forth Links, Resources, and Success Stories
A group browse of the Web in search of material to add to the SVFIG website.

Al Mitchell - amrFORTH Version 6
An example of cross-platform GUI Forth applications without Windows calls or a GUI Forth and without license fees. We have created a tethered Forth GUI environment which works equally well on Windows or Linux/BSD by creative use of Tcl/Tk and gforth. Forthies will be comfortable with the command-line Forth environment yet use these modules to create a GUI interface for clients and the general public.

Randy Thelen - Mippy - TTL Forth
Randy will talk about a 16-bit Forth-based processor that he built from 7400 series TTL logic. His presentation will include an overview of the project, his motivation for pursuing it, project details, what he learned, block diagrams, and a photograph of the board.

Joseph M. O'Connor - A Forth-like Scripting Language in Borland Delphi
Creole is a simple Forth-like programming language developed as a component in Borland Delphi. It is similar to Norman Smith's UNTIL in that it was designed as a scripting language that can be tailored to a specific application. It has several unusual features, which include string-based processing and the ability to filter and transform data based on rules defined by the programmer. This presentation will discuss the internal structure of Creole and give some simple examples of how it can be used as a scripting language embedded in an application.

Jeff Fox - Special presentation
Presentation description is forthcoming.
