Olde Tyme Forth Systems - CH Ting Ting has
reactivated 8086 FIG Forth, F83-MSDOS, and FPC, on his Windows XP computer. He
has also updated eForth and Zen. It was nice to see these old Forths
still working! Ting will demonstrate them in the meeting so we can all
reminisce. He will also show new electronic editions of his Systems Guide to
FIG Forth, Inside F83, eForth, and Zen, all available on his website. Ting used
an old version of Acrobat to add chapter bookmarks to these three books,
producing an improved appearance.

A Newbie Looks at Forth - Glen Worstell ... and
finds some things not to his liking. "I'd like to present my ideas about a
few things that I'd like to modify before doing embedded systems projects in
Forth and would like to receive feedback from the experts on reasons not to
make these changes, if there are good ones."
Glen wont consider Forth standards, as they are beyond the
scope of his talk.

Mecrisp Forth on Low-cost Hardware - Glen
Worstell
Mecrisp runs out of the box on several platforms: |
- TI MSP430 Launchpad
- TI ARM Cortex M4 Launchpad
- STM32F4 Arm Cortex M4 Launchpad
- several MSP430 and ARM Cortex microprocessors
Mecrisp is an excellent Forth implementation using
subroutine-threaded code with some code optimization. The MSP430 version
includes an assembler and disassembler, so 'SEE' is implemented (a great
feature). |
All versions can have code resident in: |
- core flash - can't be erased without reloading
- user flash - easily erased and reprogrammed in
Forth
- ram - good for debugging new words
