ALPHABET SCROLL/ATARI 2600 by Toolkitman

This is a very early stage prototype of Telewriter similar to a computer terminal for ATARI 2600, In practice you scroll Alphabet A=Z letters on the screen. By arriving to Z you have to power off on ATARI 2600 and reset then keeping pushed Joystick UP  you will scroll the letters, by stopping you will choose a letter on the screen.

Never thought your ATARI 2600 can write???
