eForth Version 1

In 1990, Dr. C. H. Ting and Bill Muench implemented the eForth model
on 8086 and released the source code.

Since then, many FORTH programmers toke this model and ported it to
a wide variety of microprocessors and microcontrollers.  Many of them
were basis of interesting applications.

These implementations are in the public domain and you are welcome
to use them in your own applications.
eForth and Zen, C. H. Ting
Complete description and exposition of the eForth kernel, high level
words, interpreter, compiler and utilities.  Comparison of Forth and Zen,
their similarities in historical development and in their strife towards
simplicity and understanding.

8086 eForth Model, Bill Muench and C. H. Ting
A small portable Forth system designed for microprocessors of the 90's.  
31 machine dependent kernel words and 191 high level words.  
Separated code and name dictionaries.  Source code is in Microsoft
MASM assembly.  Disk and eForth Implementation Guide.


8051 eForth, C. H. Ting
A small ROM based Forth system for the popular Intel 8051/31
microcontroller.  Source code is in Microsoft MASM assembly.  Easily
modifiable to suit specific ROM/RAM configurations.  Source code on
an IBM 5.25" disk.  With 8051 eForth Implementation Note.

68000 eForth, Richard H. Haskell
A 32-bit 68000 implementation of eForth for the Motorola ECB Board.  
Dr. Ting also contributed a file in that MASM is forced to produce code
in the Motorola byte order.

32-Bit 8086 eForth, Rick VanNorman
This is a 32 bit implementation of eForth for 80x8x family of processors.
 Much of the high level code are rewritten in assembly to improve the
performance.  The object code is generated by a Forth metacompiler
(included), not from MASM source.  Many other utilities are provided
and are good eForth coding examples.  

Z80 eForth, Ken Chen
Ken Chen is a member of Taiwan FIG Chapter.  He moved eForth to the
popular Z80 processor with significant enhancement.  It also contains a
diagnostic program for eForth which allows the implementor to debug
eForth during cold boot.

Subroutine Threaded eForth, R. H. Haskell
Dr. Haskell recoded eForth using subroutine threading so that all high
level words can be executed and tested as coded words.  This disk
includes 68000, 68HC11 and 8086 implementations with a host
interface in F-PC.  

68HC11 eForth, Karl Lunt
This eForth is based on a public domain 68HC11 assembler ASM11.  
The native assembler makes it easier for the user to extend the eForth
and optimize the kernel for specific applications.

8098/96 eForth, Kezhong Ting
This eForth for the Intel 8098/96 family of microcontroller is contributed
by an author from Nanjing, People's Republic of China.  Also includes
a 8096 assembler written in FPC.

Pic17C42 eForth, C. H. Ting
eForth for Microchip's 16-bit high performance microcontroller.  Written
in ASM17 assembler.

8051 and 68HC11 eForth, W. Schemmert
Opitmized eForth for
8051 and 68HC11, written in native UCASM
assemblers.  Most of the documentation is in German.  Supplied with
EFTERM terminal emulator.

Transputer eForth, Bob Barr
eForth for Inmos 32-bit transputers.  This is an experimental
implementation not yet tested on a Transputer system.  Volunteers are
welcome to put this system to the test.

MIPS eForth, C. H. Ting
eForth implemented for MIPS microprocessors in Silicon Graphics
Workstation.  Use a small C loader and call I/O routines in C library.

H8 eForth, Bernie Mentink
Mentink of New Zealand contributed this eForth for H8/532 from
Hitachi.  H8 is very powerful.  It has on-chip counter/timers, 3 PWM,
10-bit A/D, 65 I/O pins, 1Kb ram 32 Kb OTP ROM, 20 MHz crystal.

7810 eForth, John Talbert
John Talbert at Oberlin Observatory contributed this for NEC78C10.  
7810 has 3 8-bit I/O ports, 8-bit A/d, serial I/O, 256 bytes of RAM and 10
16-bit registers.  Another powerful Japanese microcontroller.

32-Bit 386 eForth V.4.02, C. H. Ting
This is a 32 bit implementation of eForth for 80386 in the protected
mode.    It enters into protected mode directly under DOS through an
OK loader.  Only COM1 is active at 9600 baud.  Keyboard, screen and
disks are all silenced. You need another PC to serve as a host through
the serial port.

56002 eForth, Dave Taliaferro
First working version of eForth for Motorola 56002 DSP chip. Include
Motorola 56000 Assembler and the assembler manual.

68HC16 eForth, Pete Zawasky
A direct threaded eForth assembled with Motorola ToolWare M68HC16
Assembler and used on M68HC16EVB board.

Java eForth, Michael Losh
Java implementation of eForth for Java Virtual Machine.  Token
threaded, word addressing, accessed through a console-style Java
applet.  Opened in a browser like Netscape Navigator and Microsoft
Internet Explorer.
