<p>Once you have downloaded SAT_OS, just unzip the copytoh89.zip file contents to a folder on your computer. Next copy the appropriate .89 asembly files to your calculator "main" folder. </p>
<p>After that, unzip the contents of the sat_os.zip file to a folder on your computer. Copy all of the contents of that folder to your calculator (except for the screenshots and the README file - just the .89p program files) using a linking cable and TI-Connect.</p>
<p>To start the OS, simply hit "catalog," hit F4, then hit the number "3" key (for the letter "s"), and goto "satmenu()." Close the parentheses and you're set. This will allow for rapid access to the OS</p>
