14 Facts About Tektronix 4014

Tektronix 4014 4010 series was a family of text-and-graphics computer terminals based on storage-tube technology created by Tektronix 4014.

Tektronix 4014 decided to enter the computer terminal market themselves, introducing the 4002 in 1969, and the updated 4002A in 1971.

The upgraded features became so widely-used that the Tektronix 4014 series is sometimes considered to be a separate line from the 4010, or alternatively the canonical model for the entire family.

Properly equipped Tektronix 4014 could drive a pen plotter through an expansion card, including the GPIB-based 4662 Interactive Digital Plotter and 4663 C-sized version.

Tektronix 4014 continued selling the basic storage tubes to OEMs, the 19-inch version as the GMA101 and 102 and the 25-inch as the GMA125.

Tektronix 4014 sold a set of graphics software routines in FORTRAN known as PLOT10 that converted simple inputs like lists of numbers into a graphic display such as a chart.

Tektronix 4014 had originally developed their storage tubes in the late 1950s as a way to store images on oscilloscope displays for study, although the same system had already been used in radar displays.

The Tektronix 4014 approach had the advantage that there was no limit to the number of vectors that can be displayed; one could simply keep adding them to a complex image, whereas a solution like the IBM terminal had a limited number of vectors it could refresh on its display.

Tektronix 4014 introduced the write through concept for non-stored vectors, but with the terminal itself lacking any memory, the data had to be continually refreshed from the host computer.

Tektronix 4014 referred to this as the stored writing speed, and measured it in terms of vector-inches-per-second, with ratings between 1500 and 4000 being typical for their displays.

The Tektronix 4014 terminal was normally shipped with the standard Communications Interface installed, offering an RS-232 connection, although only the most important connector pins were supported.

Tektronix 4014 series had a number of minor changes and some more major improvements.

The Tektronix 4014 added escape codes to allow the user to select this mode deliberately by sending any of the sequences from Esc+p through Esc+w.

Tektronix 4014 made a change to the way graphics points were entered by adding an execution character which denoted that a particular coordinate was complete.
