For anyone wondering, the original implementation was on a PDP-11 clone called Electronika 60 https://tetris.wiki/Tetris_(Electronika_60) ... not the 1989 Game Boy version most people consider to be the "original" :)
I've got the backplane and boards to build a more-or-less LSI-11, the original system cloned by the Electronika 60. One day I really want to load the original Tetris onto it somehow... Would probably have to use a terminal emulator to get the Cyrillic character set to render, but I bet it's possible!
