Tandberg Documents

TDV 2200 Hardware Manual October 1980, Revision 0

Tandberg TDV-2114 and TDV-2124 are computers from Tandberg. From this thread, the TDV-2114 is identical to the Siemens 6.610 (OEM version). Extensive docomentation exists

Tandberg TDV 2324

Regarding the TDV 2324 computer: it could run CP/M or TOS.
TOS was Tandberg Operating System and we used it when developing the TDV 2200 series terminals.
I don’t remember much of it but it did not have a filesystem with folders. All files lay flat.
My first 2324 did not have a hard disk just two floppies.
The first floppy had the TOS OS, the second floppy contained the terminal source code and compiled files.

A EPROM burner was connected and for some terminal sw there was  some messing with addresses to get the sw correctly to the eproms.

Timeline for Tandberg terminals and computers, from :

A bit of history, the evolution of these machines is something like this:
* TDV-2000 (197?) - First terminal
* TDV-2114 (1976) - First computer (8080-based, 16-56KB RAM, TDV-2115 terminal hardware-module built-in)
* TDV-2124 (1980) - Same as TDV-2114, but with double-side double-density disk support. 56KB or 64KB RAM? (not sure if all 64K on the RAM board is available)
* TDV-2324 (1982) - Completely new design, 8085-based, 64KB RAM, HDD support, fully backwards-compatible with 2100-series

ND Hardware

Stian Sletner's Norsk Data notes on WTFwiki, about a ND-5400ES.

2016-10-18

it looks like it was a problem that has been fixed. WTFwiki now has an IPv4 address again, and archive.org has a copy of the two pages about the ND machine (because of manual effort by another member here).

2016-10-04

looks like WTFwiki is gone now, and archive.org doesn't have a copy.

correction - it is available, but only via IPv6.
