The Tandberg TDV 2215 terminal[1] was produced by Tandberg Data as a model of the TDV 2200 series terminals, and sold by Norsk Data[2] (ND) as product number ND 242, Display Terminal Tandberg TDV 2215. It can be run in a TDV 2115 compatible mode, or in its native mode.

Features

Notable features.

PUSH-keys

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 transitted 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.

Language versions

The terminal exists in several versions (different local language): Danish, English, French, German, international, Norwegian and Swedish.

Options

Available options:

  • ND 243 RS 232/V 24 Printer Interface for ND 242
  • ND 244 Current Loop Interface for ND 242
  • ND 245 Print Buffer for ND 242

Termcap

I found a termcap[3] file with entries for the TDV 2215 and other terminals. And one[4] with comments, too.

Other info

Setup

To access the setup menus, hold down the CTRL key and press the HELP key twice in quick succession.

Interfaces

Standard

The terminal has the following standard interfaces (resident on mainboard):

  • Channel A: V.24, V.11
  • Printer: V.11
  • Keyboard: V.11

Optional

Optional interface adapters (plug-in boards)

  • Channel A: Current Loop
  • Printer: V.24, Current Loop
  • Channel B: V.24, V.11, Current Loop

Note: the terminal can only have two optional interface adapter boards at the same time.

Mainboard versions

The mainboard has been produced in two versions:

  • early version: revision level 10 - 14
  • new version: revision level 15 and higher.

The new version was introduced in October 1981, and uses static RAM chips instead of dynamic RAM chips. The two versions are interchangeable.[5]

Non-volatile memory

The terminal has 512 bytes of non-volatile memory used for storing Soft-switches and PUSH-key strings. This memory is an EAROM[6] organised as 1024 x 4 bits.
