Forth for Arduino? - CH Ting
Ting feels that
the Atmega328 chip on Auduino boards is very hostile to Forth because of its
Harvard architecture. As a result of the organization of the Atmega, it is very
difficult to write to flash memory in order to extend the Forth dictionary.
Ting is experimenting with Arduino Uno and amForth, but could not get it
working on Uno
Ting hopes to get an eForth interpreter to work on Uno.

eForth Running on a GA144 - John
Rible
GreenArrays just received 16 wafers of GA144s. That's some
3,000,000 Forth computers! John will give a quick overview of GreenArray's
latest offering. Chips will be available in March, April, or May. |

ForthBildungsGruppe - Carsten Strotmann
The
ForthBildungsGruppe in Germany is giving Forth Workshops at Open Source
Conferences and using amForth on Arduino to get "fresh blood" into the Forth
community. The name of the group is a German wordplay on Forth and
Training.

Arduino Day and Maker Faire - All Present
We'll
briefly talked about plans for an SVFIG booth at the Maker Faire. CH Ting
volunteering to lead the effort to come up with a suitable display project.
We'll also discuss an Arduino Day theme for our February meeting
(see below) and the desirability of publicizing it widely. |

NaClForth - Brad Nelson
NativeClient (a feature
of the Chrome web browser) allows native machine code (x86-32, x86-64, arm) to
run in the browser with access restrictions similar to Javascript. Brad
presented a work-in-progress implementation of a colorforth variant for this
platform.
