READ 100-FORTH-INTERNALS UNDER TANDY-SUPPORT. THAT FORTH IS NO GOOD!!!

COMPUTER FAIRE FOR $100.00. (!).
IT REQUIRES AT LEAST 24K BYTES FOR OPERATION.  THE SYSTEM APPEARS TO OCCUPY
ABOUT 9K AND ALLOWS ABOUT
.. FOR BUFFERS AND DICTIONARY SPACE. NEITHER AN
EDITOR OR ASSEMBLER IS INCLUDED. SUSPECT A 32K MACHINE WOULD BE NECESSARY TO
RUN WITH ANY EASE.
  GLEN HAYDON APPARENTLY CODED THE FORTH.

RADIO SHACK now has TRS80 MODEL 100 tech. Ref Manual for $9.95
It has calling sequences and schematics.
Not too great but best out yet.
Has anyone used MULTI-PLAN on the 100, it is supposed to be a ROM?
Has anyone used any FORTH on a 100?
It would be nice if there was a ROM based one to leave the Ram for data.
The model 100 is getting cheap enough to make a super stand alone controller.
It is a little limited with number of I/O pins to the world though.

I called Tandy in Fort Worth in hopes of receiving info about Model 100
internal routines.  They told me they had no such information and suggested I
try the Compuservu Model-100 SIG. Ugh.
  The November '83 issue of the TRS-80 Microcomputer News contains a summary
of a number of ROM routines (LCD, Keyboard, Printer, Sys/1/Modem,Casette &
RAM files).  It does not, however, say anything about how to pass parameters
to these routines.  The issue should be available at most Tandy Computer Ctrs.

THE REFERENCED FORTH FOR THE 100 IS A WARMED OVER MVP FORTH WITH ABSOLUTELY
NO HARD STORAGE AND ONLY 8 BLOCK BUFFERS IN MEMORY. IT IS INADEQUATE FOR
ANY SERIOUS PURPOSES, EXCEPT POSSIBLY LEARNING SOMETHING ABOUT FORTH. THE
DOCUMENTATION ONLY TELLS YOU HOW TO LOAD THE TAPE. IT IS ALSO SLOW. AS TO 100
INTERNALS, THE CALLS ARE PROPRIETARY TO MICROSOFT, AND VERY, VERY HARD
TO COME BY UNLESS YOU FIND STUFF BY THE BLACKMARKET AND BACK ALLEY.

BYTE MAGAZINE MAY 1984 PG.288 CONTAINS SOME USEFUL INFO ON MODEL 100 ROM
ROUTINES:
ALSO HAS PROGRAM TO DETERMINE LENGTH OF FILES. VERY INTERESTING!

MOVING SCREENS INTO AND FROM TEXT F
E ADDRUSSES
THESE SCREENS CAN BE UP OR DOWNLOADED TO OTHER SYSTEMS. A WORD THAT ALLOWS A
CALL TO THE INTERNAL M100 SYSTEM WOULD BE HELPFUL. ALSO, I HAVE HEARD
THAT SOME EXPERIMENTERS HAVE SUCCESSFUL USED THE
RS232 PORT FOR DISK I/O. IF I FIND MORE INFO I WILL PASS IT ON.
LIKEWISE, ANY CONTRIBUTIONS TO THIS PURPOSE WOULD BE APPRECIATED.
