This rotation system was used in [[Tetris (IBM PC)]]. Presumably the Electronica 60 version is identical, but this is difficult to test without one of those machines. <!-- emulation? -->
It is identical to the right handed version of the [[Nintendo Rotation System]], except that the horizontal orientation of the I piece is one block higher.
 
It is absolutely identical to [[Nintendo Rotation System]], right handed version, except that the horizontal orientation of the I piece is one block higher.
 
Games using this rotation system generally have no [[wall kick]], [[lock delay]], no [[ARE]], and depend on keyboard repeat rate for their [[DAS]]. <!-- possibly an unfair generalisation -->
