What's in the box

TI Compiler

My programs

My third programmable calculator, a second hand one I got around 1985. I first had the TI 57 and then the TI 66 before the TI-58C, yet obsolete compared to thenew LCD machines with low cost and low power. No more AC adapter needed.

A true poket computer:

complete instruction set
480 steps for the 58C and the double for the 59
ROM modules with 5000 steps of various applications
good math precision
optionnal thermal printer with alphanumeric character set
magnetic card reader for the 59.

Some defaults:

the keyboard is not eternal
system with AC adapter

Printer PC-100

Here is the TI-59 onto its thermal printer: no ink cartridges to change.

On the right, the alphanumeric character set:
make your programs talk...

TI Compiler & TI Compiler Shell:

Last version 1.66, April 4th 2009.
Last update for Shell, April 18th 2009.

minor corrections
help buttons and WEB link

Here is the way to program your TI 59 with the facilities of a high level language:

variable names that replaces the register numbers
label names, flag names
comments
addresses calculated at compilation time
structures as LOOP/WHILE/UNTIL/FOR and IF/ELSE/ENDIF
structures as SELECT, CASE, DEFAULT, ENDCASE
calculated goto ON reg { ... }
multiple assignment
array notation
printing operations
Macros with parameters

It ouputs the listing as the TI printer does with:

step numbers
key codes
mnemonics with 3 characters

Now, it is interfaced with three emulators andgenerates the files loadable by each (see below):

the TI-59.EXE emulator for Windows
the TI59ce emulator running on Pocket PC!
the brand new emulator from Alain Zanchetta under Windows

The TI Compiler Shell, the graphic interface is available!
Included: french and english documentation with automatic installer for Windows.

The Shell with the edition window, the listing, the MS-DOS window for the compiler and the Windows TI-59 emulator.

TI Compiler is a DOS program, 100% assembly A86, that just requieres a PC XT under DOS 3.xxwith 128 Kb ram. It provides simple commands to define register and label names, facilities to use the unofficial HIR functions, pseudo-opcodes to replace dark operations (as OP 2x or OP 3x remplaced by INC and DEC) and a lot oferror messages to ease the debugging.

You can download TI Compiler, the file contains:

TICOMP.COM: the compiler 16Kb!
Ticomp.DOC: the complete user guide
History.txt: the versions
Ticomp.s: assembly source
TISOURCE.TXT: an example
TILIST.TXT et TIEMUL.T59 two files generated by the example

Some examples:

Replace register numbers and key labels...

  LBL A
  RCL 00
  x²
  STO 01

...with variable names and procedures names!

#label A au_carré

   x=t 017
   RCL 00
   +

   RCL 00
   +
   RCL 01
   =
   STO 02
   1 0 0 0
   SUM 00
   SUM 01

...with visible logical units, with multiple affectation, sum or product:

   #reg 2 somme
   #reg 0 x
   #reg 1 y

   somme={ @x + @y = }
   x,y+{ $1000 }

Replace indirect addressing in non clearly defined zones...

   4 STO 00
   9 STO 05
   RC* 00 x%t
   RC* 05
   INV x=t 022
   OP 35
   DSZ 00 006
   R/S
   ...

...with an array notation!

   #ARRAY tab_1 1 4
   #ARRAY tab_2 6 9
   #reg 00 I
   #reg 05 J
   
   I={ TOP tab_1 }
   J={ TOP tab_2 }
   FOR I
      @tab_1(I) x%t
      @tab_2(J)
   WHILE(x=t) difference
      DEC J
   WEND
   R/S
 difference: ...

Replace codes and printing operations...

   6413351713
   OP 04
   1 0 x² * Pi =
   OP 06

...with text and clear orders!

   "=area line>>
   $10 x² * Pi =
   MixLine   ; this prints
   ; 314,1592654 =area

The TI Compiler generates the complete listing for you to program your calculator...

... but also the file loadable with the TI-59.EXE emulator for a fast test and immediate debugging. (The default file name is TIEMUL.T59 and can be altered using #EMULATOR command).

Link with TI59ce on Pocket PC

TI59ce is the second emulator supported byTI Compiler. It runs on Pocket PC and SmartPhone and is always updated by its author Alain Zanchetta.The previous emulator suffers from rare bugs that will never be corrected... Try this with TI-59.EXE:

8888888888 2nd INT

We expect

8888888888

But it returns

298954296.0

This bug doesn't exist in TI59ce that I recommend to you as its author is still active.

Under Windows XP, I use Microsoft's Device Emulator to simulate a Pocket PC and use TI59ce!For Device Emulator setup, please contact me.

TI Compiler outputs the file TIPPC.TI (default name, change it with #POCKETPC command) that TI59ce can load usingINV 2ND WRITE:

The brand new emulator by Alain Zanchetta for Windows.

Based on his work for the PocketPC, here is his PC version.
Numbers format has been totally reviewed to match the 13 digits decimal precision of the calculator.

This emulator comes with a debugger with register viewing and breakpoints!

Great work than you can download here.

TI Compiler outputs the file TIWIN.TI (default name, change it with #AZEMULATOR command) that the emulator can load usingINV 2ND WRITE

Pierre Houbert's emulator for Windows.

Brand new, still under development, an emulator full of promises. The author wrote a great documentation, precise and complete, in PDF format (in french).

It doesn't only emulates the TI-58/59 with its PC100 printer, it extends the OPnn codes with amazing capabilities :

Alphanumeric display on screen

Prints 5 simultaneous curves with 100 pixels precision

Numeric jumps managment enhanced as insertion/deletion of one step updates the program

And many more..!!

The emulator in TRACE mode with listing and registers display

Dave Ramey's programs Thanks!

Here's an active TI-Shell user!

(April 13th 2010: PRJ files fixed)
Download TI59PROGS, a set of programs sent by Dave Ramey, some are his own creation,others come from different magazines. You'll find:

13DIG/PRT/VUE print or display a value with full 13 digits precision
BASECONV bases conversions
DATALIST
EASTDT Easter date for a given year
FIB Fibonacci numbers
GCD Greater Common Divisor of two numbers
MOON moon phase according to the date
NIMB a game against the calculator
PRIME tells you if a given number is prime or not
PRIMFACT gives the prime factorization of a given number

New programs since the last update (with project file for the TI Shell):

CASHFLO complete financial tool
INTEG1 integral calculus, trapezoidal method
PALNUM funny math program around palindromic numbers
PRTCAL print the calendar of a given month
QUADEQU quadratic equation with optional printing
RUN-KUT differential equation, Runge-Kutta method

Another hard work from Dave, here are the sources of the Maths Utilities library that you can use,read or modify:

Maths Utilities

Prime factors
Differential equations
Super plotter
Equation solver
Romberg's Integration
...

Module Usage

Yet another Dave Ramey's contribution! Alain Zanchetta's emulator allows you to load modules and the debugger now can display the HIR contents. So Dave has rewritten the source code from various modules with the file loadbale by the emulator:

Master Library (included with the emulator)
Maths
Survey
Leisure

Each ZIP contains the sources and the *.MOD file loadable by the emulator.Victor Toth offers on-line the manuals of the modules here!

My programs

Each ZIP archive contains:

*.LST: The program with steps and codes
*.T59: The same but loadable by the emulator TI59.EXE written by Miroslav Nemecek
*.ENG: English help file for the emulator, rename it as *.TXT
*.FRA: The same in french
*.DOC: General informations about the program, both french and english
TISOURCE.TXT: Includes the new source file for TI Compiler; Includes a version for the printer PC100
