NORD-1 Serial number 47 was given to me by Fagskolen Innlandet in Gjøvik, Norway in the summer of 2016. I think it's been at the school for all of it's life since the only inventory labels on it is from the school. The only documentation surviving is the lists of cards on the inside of the front door. They give a date of summer 1972 as the build date.

NORD-1 with the door open.

Configuration

The system is equipped with

  • 32 kword of core memory
  • 9 TTY interfaces
  • A cartridge disk interface
  • An I/O channel (connectors I/O channel data in, I/O channel data out, I/O channel control)
  • Asynchronous modem
  • Centronics printer interface
  • Facit punch 4070 interface
  • Digitronics tape reader interface

Missing parts and damages

Some cards seems to be missing and minor damages 

Shelf D :
* Missing cards on position 27 and 28.
 -- 27 : 113 I Card reader contr.
   I have no drawings or extra cards of this one, can be hard to reproduce.
 -- 28 : 179 Punch buffer
   There is a drawing of this card in the manuals I got from Tingo,
   it should be possible to reproduce.
Shelf E :
* Missing card on position 20.
 -- 20 : 195 Duplex start stop buffer for TTY 6
   There are several cards of this type in the machine, so no problem to reproduce.
Shelf F :
* Missing cards on position 25 and 26.
 -- 25 : 185,8 Data ch. M data in
 -- 26 : 185,7 Data ch. M data out
   There are one more of card 185 in the machine, so no problem to reproduce.
Some switches are broken on the front panel.

Card cage configuration

According to Norsk Data Document ND–01.004 NORD-1 HARDWARE MANUAL there are two different CPU:s, no. 29 and no. 35. The cpu in this machine seems to be a no. 29.

Core memory

Core memory

The core memory was made by Cambridge Memories INC, Newton, Massachusetts or CMI, the model name is EXPANDACORE 18. The memory have two or four channels in to it so it is possible to build a multi CPU machine by connecting two (or maybe more) to the same memory to pass messages between them. The core memory is built up from modules. One rack can hold four controllers and eight memory planes of 4 kword each. It looks like the original configuration only came with 24 kword but later on two additional memory planes were added.

Current status

The system resides in the ND-Collection in Umeå. It is not operational yet but there is good hope that I will be able to restore it to running status.

Plans

The system will be put in working order some time in the future. First it will be documented.

  • Serial number plate.

  • Early logo before the name change to Norsk Data AS.

  • Wiring loom at the back of shelf E and F.
