Historical Terminal · 1993 · Digital Equipment Corporation (DEC)
The DEC VT510, released in 1993, arrived near the end of the hardware terminal era. DEC followed it with the VT520 and VT525 (adding dual-session and color capabilities respectively) before Compaq acquired DEC in 1998, ending the VT line. These were among the last dedicated hardware terminals manufactured — the industry was shifting to PCs running terminal emulator software.
While no modern terminal implements the full VT510 specification, specific features it documented — DECTCEM (cursor visibility), DECSCNM (reverse video), DECCOLM (132-column mode), DECSCL (conformance level), and numerous private modes — became universal in software emulators. The VT510 was also the first DEC terminal to support multiple sessions on a single screen.
The VT510 Reference Manual remains the most cited document in terminal emulation development. At over 600 pages, it is the closest thing to a comprehensive specification for DEC escape sequences, covering everything from basic cursor movement to obscure private modes. When terminal developers encounter an unfamiliar DEC sequence, the VT510 manual is where they look — it has outlived the hardware it described by decades.
