I am collecting here what versions can be found of the original DOS Tetris by Pajitnov and Gerasimov. Released for free in the late nineteen-eighties, the original DOS Tetris used the 16-color text display mode with block characters for the tetris pieces. Later, there were commercial editions of Tetris with fancier graphics, for various platforms.

The version I remember running back in the day, which I downloaded from the BBS of San Diego computer magazine Computor Edge, seems to have been an earlier version than these two I can find on the web now. It didn't have the dotted vertical guide lines, and I sort of remember it using solid characters for the walls of the playfield cup.
