The Tektronix 4051 desktop computer has been redesigned with twice as much memory and additional functions at no additional cost. A stand-alone computer with built-in high-resolution graphics for analysis, decision making, and model building, the 4051 now includes 16K bytes of memory, as well as built-in matrix and binary loader functions, previously available as options.
