Why It Flopped

 * 1) Letters could only be typed in uppercase.
 * 2) The computer was only compatible with its proprietary display, a bulky 13-inch Zenith TV.
 * 3) No option for an 80 column display mode at launch.
 * 4) Only a limited selection of hardware was available.
 * 5) The computer was eventually sold for such a low price of $99, people began thinking that the computer was of very low quality and that Texas Instruments had to drop the price to make it sell.

Redeeming Qualities

 * 1) It is the first 16-bit computer ever released.
