The Tandberg TDV 2220 terminal was produced by Tandberg Data in 1980 as a model of the TDV 2200 series terminals. This terminal is ECMA-48 compatible, with forms and editing functions. Fun fact: In December 1982 the computer installation at Risø National Laboratory in Roskilde, Denmark. had two Tandberg TDV 2220 Visual Display Units.
TDV 2220 is the "top-of-the-line" in the TDV 2200 series. It can be used both as a character-by-character and a buffered terminal. The control codes used are based on international standards (ECMA-48, ANSI X3.64 and ISO DP 6429).
Standard line interface is V.24 and V.11 (only one can be used at a time), current loop optional. Standard printer interface is V.11, V.24 or current loop optional.
The terminal has eight PUSH-keys, providing (by use of SHIFT) sixteen functions. PUSH, Programmable Utility for String Handling, allows the user (or the host computer) to program often used words or code sequences that can be transmitted by pushing the appropriate PUSH-key. The strings associated with PUSH-keys are stored in non-volatile memory and are not lost when power is turned off.
A local printer can be attached. Printer commands for printing all or parts of screen content. Local and remote printer control, giving hard copy, terminal bypass or transaction logging. Optional one-page print buffer enables printing to be done as background activity.
Settings in non-volatile memory
Certain terminal characteristics are determined by switches residing in non-volatile memory. Switches can easily be altered using self-explanatory menus
