The Hazeltine 2000 is one of the first general-purpose "smart" computer terminals,[1][a] introduced in October 1970 at a price of $2,995 (equivalent to $23,500 in 2023). While earlier terminal systems included "smart" editing features, notably the IBM 2260, the Hazeltine 2000 was the first that used a standard RS-232 interface and sent its control sequences in the data stream. It could be attached to any contemporary minicomputer or mainframe that had a serial port[2] and used ASCII-standard character sets.
One advanced feature of the design was the concept of "batch mode" that cached data being typed by the user and sent it all at once to the host. The system also had two display intensities, foreground and background (bright and dim). Data sent in background mode was independent and not sent back to the server. This allowed forms to be sent as text in background mode and then switch the terminal to foreground mode for data entry. This was used to create on-screen forms that could be filled out and cleared without having to re-send the background layout.
The base model displayed 27 lines of 74 characters, uppercase only, while an expansion added lowercase and 80-by-25 layout. In 1974 the expanded version became the only model and the price was lowered. The basic system was reimplemented several times using newer electronics as they became available during the 1970s. The Hazeltine 1500 was a lower-cost version introduced in 1977. The development team was unhappy with the support they received from the corporation, and the division was spun off to form Esprit Systems.
