The Tektronix 4012 is a high resolution graphics terminal, essentially a 4010 with added lower case characters.

The 4013 is a 4012 with an added APL character set. These upgrades were implemented using plug-in boards that could be added to the base-model 4010 as well.

A version small enough to fit on a desk, using a built-in RS-232 port (and missing a number of features) was released as the 4006 in 1976.
