Texas Instruments TI 58C/TI 59

Version Française

On the left, the TI 59 with its card reader, on the right the TI 58C with a module software.

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:
  1. complete instruction set
  2. 480 steps for the 58C and the double for the 59
  3. ROM modules with 5000 steps of various applications
  4. good math precision
  5. optionnal thermal printer with alphanumeric character set
  6. magnetic card reader for the 59.
Some defaults:
  1. the keyboard is not eternal
  2. 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:
Here is the way to program your TI 59 with the facilities of a high level language:
  1. variable names that replaces the register numbers
  2. label names, flag names
  4. addresses calculated at compilation time
  5. structures as LOOP/WHILE/UNTIL/FOR and IF/ELSE/ENDIF
  6. structures as SELECT, CASE, DEFAULT, ENDCASE
  7. calculated goto ON reg { ... }
  8. multiple assignment
  9. array notation
  10. printing operations
  11. Macros with parameters
It ouputs the listing as the TI printer does with:
  1. step numbers
  2. key codes
  3. 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:
  1. TICOMP.COM: the compiler 16Kb!
  2. Ticomp.DOC: the complete user guide
  3. History.txt: the versions
  4. Ticomp.s: assembly source
  5. TISOURCE.TXT: an example
  6. TILIST.TXT et TIEMUL.T59 two files generated by the example
Some examples:

   x,y+{ $1000 }
Replace indirect addressing in non clearly defined zones...

...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
   WHILE(x=t) difference
      DEC J
 difference: ...
Replace codes and printing operations...
   OP 04
   1 0 x² * Pi =
   OP 06
...with text and clear orders!
   "=area line>>
   $10 x² * Pi =
   MixLine   ; this prints
   ; 314,1592654 =area

... 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
But it returns
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: New programs since the last update (with project file for the TI Shell): Another hard work from Dave, here are the sources of the Maths Utilities library that you can use,read or modify:

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