The first terminal to showcase a screen as output device (rather than paper) was the Datapoint 3300 by Computer Terminal Corporation (CTC).[^2] Other than having a glassy CTR screen, the main feature of the Datapoint 3300 was that it could seamlessly replace the Teletype Model 33 terminal and perform paperless the same operations. However, the Datapoint 3300 had obviously different circuitry than the Model 33. In order to drive its CTR monitor, CTC devised special electronic circuitry that kept track of the characters displayed on screen (shift-registers - a type of operational memory). The story goes that CTC, having a need to upgrade its circuitry, asked Intel and Texas Instrument (which are integrated circuit manufacturer) to produce a special ship that would be used to program its future screen-based terminals.[^3] This challenge lead to the development of one Intel's first 8-bit microprocessor - the Intel 8008.[^4]
The direct descendant of the Datapoint 3300, the Datapoint 2200 was the first programmable terminal, viewed by many as the first personal computer. The fact that the Datapoint 2200 was programmable, meaning that code could be written for and ran on the terminal's circuit itself and not on a mainframe made it very attractive to computer programmers. Commands could be issued on the Command Line Interface and directly resolved locally without the need of an (expensive) mainframe. This were the story of terminals ends. If code is executed locally and not remotly, it is erroneous to talk about a terminal but instead
