FORTH ON HP COMPUTERS

*** HP                   22-OCT-84
  PARENT=SYSTEMS              USAGE=367
Has any one used the FORTH module for the HP-71B? Ifso, what is your
opinion of it?? The module also sontains an Assembler (Hence the name
FORTH/Assembly>  written in FORTH to allow extensions to the FORTH operating
system (new primitives) and Language EXtension files (new keywords) to the
Basic operating system. The module has the ability to use a Dumb-Terminal
as the HP-71's keyboard and display devices with an HP-IL/rS232 Converter
making it a suitable development system for application software.
all internal documentation is avaliable for sale through Hewlett-Packard !

*** HP110-FORTH          17=DEC-84
  PARENT=HP                   USAGE=269
There is an implementation of FORTH for the HP110 in the XA1 database of the
Interex SIG on Compuserve.  Although I have not used it, other users seemed
pleased.  Intend to download it after the first of the year; will report
back here. (Note: fee is VERY reasonable)  More details to follow...
Thanks for the Tree.                       -Wes Erickson

SOME COMMENTS ON HP71B FORTH/ASSEMBLER MODULE:  71B R:
 NIBBLE
-ORIENTED MACHINE WITH 20-BIT ADDRESSES.  FORTH ON 71 IS A 20-BIT
IMPLEMENTATION.  SEVERAL NIBBLE WORDS ARE PROVIDED TO ADDRESS THIS
CAPABILITY, SUCH AS NALLOT, N@, N!, ,NFILL,NMOVE,5+(INCR ADDR BY 5),
5-(DECR ADDRESS BY 5).  FORTH BLOCKS OR SCREENS ON THE 71 ARE STANDARD
TEXT FILES, AND CAN HAVE UP TO 96 CHARACTERS PER LINE, WITH AS MANY
LINES AS YOU LIKE.   FULL FLOATING POINT OPERATOR USES NATIVE BASIC
SYSTEM ROUTINE FOR EVALUATION OF ANY FORTH NUMBERS WiTH DECIMAL
POINTS.  CONFORMS WELL WITH 83 STD.  IF YOU AREN'T INTERESTED IN THE
ASSMMBLER, CONSIDER GETTING THE "TURBO-41" PACKAGE FROM EDUCALC
(800-633-2252).  PLUG-IN ROM INCLUDES HP-71 EMULATOR AND TRANSLATOR
FOR HP41 PROGRAMS, WITH ADDITIONAL FUNCTIONS, AND A  SIMILAR FORTH
IMPLEMENTATION TO HP'S ROM.  COST IS 30$ LESS THAN HP ROM.  SEE DESCR IN
CHHHU CHRONICLE, V2N1 JAN/FEB'85, ARTICLE BY WILLIAM WICKES, WHO
PROGRAMMED THE MODULE.

*** HPSERIES-80-FORTH
  PARENT=HP                   USAGE=184
In an upcoming issue probably May/June) of PROFESSMONAL COMPUTING
magazine, for HP-pc user's, writer Don Person will be devoting his column
to a letter I wrote concerning FORTH implementations for HPSeries-80
computers.  The main FORTH (and almost the only one) used for series 80
comes from the HP-User's Library, and has several drawbacks, notably
its inability to load when there are enhancement ROMs (like the Advanced
Programming or I/O ROMs) in the machine.  In response to my letter,
Mr. Person contacted the original authors of the HP80-FORTH binary, and
learned they had since CODED A ROM-BASED VERSION OF FORTH, WHICH COULD
BE CARRIED IN A SERIES-80 EPROM MODULE.  Mz. Person obtained the code,
and is considering burning-out some CHEAP FORTH EPROMS ($30), IF THERE
IS SUFFICIENT INTEREST (READ "SUFFICIENT LETTERS" FOLKS...).  Person
has already tried out a preliminary EPROM, and reports that it is fully
COMPATIBLE WITH OTHER ADDED ENHANCEMENT ROMS.  IF YOU WOULD LIKE TO
USE A ROM-BASED FORTH ON YOUR SERIES 80 COMPUTER, OR KNOW OF A SERIES
80 USER WHO MIGHT BE INTERESTED, PLEASE CONTACT: DON PERSON, A GENTLE
WIND, INC., BOX 3103, ALBANY, NY 12203---OR CALL (518-482-9023)--TO
LET HIM KNOW THERE IS A MARKET FOR FORTH-EPROMS, AND THAT THERE ARE
INDEED MANY HP USERS INTERESTED IN FORTH --Scott T. Schad, Tulsa, OK.

A further note on Forth for Hp 85,86,87 computers.  I have obtained the
Forth eproms for the
HP 86/87.  Both work fine and let you recover
a lot of low memory.  Cost is $30 from Don Person, c/o PROFESSIONAL
COMPUTING, Camden Communications Ins., P.O. Box 250, Camden, Maine
zip: 04843.  The implementation is very standard FIG model, so you wil|
probably want to order the Series 80 User's Library  for
$50, in order to get the utility screens and some documentation.  Address
is:  Hewlett-Packard Co., Series 80 User's Library,
1000 N.E. Circle Blvd., Corvallis, OR  9736. Remember that this is not a
plug-in ROM for the ROM drawer, but an eprom which must live in the
series 80 eprom holder.  If you have trouble installing the eprom, contact
Don Person, or me: Scott T. Schad, 3943 S. Delaware Pl., Tulse, OK 74105,
(918)-747-0207.  Work phone: 742-0019.
