The Texas Instruments TI 99/4A computer is awesome, but it did not come with a built-in DOS. You can't catalog a disk, delete a file, or initialize a floppy from the command prompt. TI created Disk Manager to do those things. It was later superseded by Disk Manager 2, but remains a practical and useful tool for disk functions on a stock 99/4A.
