I just received my copy of the 68HC11 ROMable Forth ... it
looks great. As a soon-to-be Forth user (I'm taking the
plunge real soon!) I have a few questions.
I would really like to get a 68HC11 based Forth system running -
but I'd like to get some more information on the capabilites of this
this implementation. The read.me file (appended below) is a port of
a version originally written for the 6800. Specifically, my
questions are:
1. Where can I get some documentation on this implementation?
I could (maybe?) figure out what is going on from the
assembly listing - but >3300 lines of code is a bit much
for a novice Forth user.
2. Can I use this version of Forth to compile programs that
will run from EPROM?
3. Does this Forth include a standard set of words (i.e.
as in Brodie's book)? Are there any extensions?
4. Would it still be possible to get the documentation for
the 6800 version from Mtn. View Press? (How many $$?)
---------------------- read.me file ------------------------
FORTH11 - Rom based FORTH for the 68hc11
This 68HC11 version of fig-FORTH is based on the 6800 implementation
of the Forth Interest Group's model that I purchased from Mountain
View Press way back in 1984. I have since lost both the 6800 source
listing and implementation guide and therefore do not have the
information as to who wrote the original 6800 code. If anyone has this
information would you please fill this in and let me know so credit can
be given to the original authors. I have also included the Motorola
Freeware 68HC11 assembler which I used to assemble FORTH11.ASM . It's
from the Motorola Freeware BBS (1-512-891-3733).
