Quick Start Guide

Welcome to the Doors CS Quick Start Guide, intended to get you up and running with Doors CS as quickly as possible. Once you have finished reading through this guide, we recommend that you return at some point to read the full user manual to help you better utilize the power of Doors CS. Without further ado, let’s begin installation of Doors CS.

Pre-Installation #

Before you can install Doors CS, you must first unzip the file you downloaded. If your computer is running Microsoft Windows XP, you can simply double click this file and select the “Extract All” tab on the side of the screen. Once you have done this, proceed to the “Transfer” Section.

If you are not running Microsoft Windows XP, Windows Vista, or Windows 7 (or newer), you may need to use software such as 7-zip to unzip the files. Follow the instructions included with your program to extract the files, then proceed to the transfer step.

Transfer #

Once you have unzipped Doors CS, you can begin the transfer.

First, open your transfer program. On Windows or Macintosh machines, you will probably do best with TIConnect software, available from Texas Instruments or on the CD that came with your calculator. For Linux based computers, a number of utilities exist and can be found at Ticalc.org.

TI-Connect Instructions

  1. Run TIConnect from your start menu.
  2. Select the “Device Explorer” button.
  3. Select the proper device from the list (Calculator should be plugged in)
  4. Open the folder you extracted Doors CS to.
  5. Inside this folder, select the appropriate version of DCS, based on your calculator model.
  6. Drag and Drop the file dcs6.8xk from the folder to the TIConnect Device Explorer.
  7. Follow the TIConnect prompts to send the file to your calculator.


  1. Find the appropiate file inside the ZIP file.
  2. Copy it to your desktop
  3. Attach calculator and turn it on
  4. Right click on file and select Send to TI
  5. Select appropiate connection
  6. Click on Send to Device to begin transfer

First Use #

Sending the file to your calculator installs it; no further installation is necessary. To run Doors CS at any time, press the blue Apps key(83+) or purple Apps key(84+) on your calculator, and either use the arrows to select DoorsCS7 and press [ENTER] or press the number corresponding to the DoorsCS7 entry in the menu. The first time that you run Doors CS, it will invisibly install an AppVar that contains default settings. You can edit these settings via the submenus of the DCS Menu in the lower left of the Doors CS desktop.

Usage Overview #

Keys #

To navigate Doors CS, use the mouse cursor, controlled by the four arrow keys on your calculator. To normal or “left” click, press the [2nd], [ENTER] or [TRACE] key. To secondary or “right” click, press the [ALPHA] or [GRAPH] key. You can turn your calculator off from Doors CS by pressing the [ON] key; press it again to turn the device back on. [CLEAR] quits immediately back to the TI-OS homescreen from the Doors CS desktop.

See Hotkeys for a comprehensive list of keys that can be used to control the shell.

Areas of the Screen #

In the main area of the desktop are up to six icons representing programs or files on your calculator, accompanied by filenames of up to eight characters. You can left-click on any compatible file to run it. If Doors CS cannot run a file for some reason, whether due to incompatibility or corruption, it will alert you to this fact. When you finish using a program, it should return you to the Doors CS desktop. You can also right-click on files to edit their options or create folders. At the right side of the screen is the scrollbar. You can expedite scrolling by using the [-] and [+] keys to go one page up and one page down respectively. You can also click on the bar itself to scroll down one page, or click the arrows at each end of the bar. The lower right of the screen contains, from left to right, the free RAM meter, the battery power meter, and the close button. The close button is equivalent to pressing [CLEAR]. The bottom left of the screen contains the icon seen in the top left of this page, the Doors CS Menu, usually abbreviated as the DCS Menu. This provides access to options and advanced features of Doors CS. Some provide redundant access to features for those familiar with desktop computer interfaces. You can read more about the DCS Menu on the DCS Menu page.
