The short version

Little is documented about this machine. It was a stripped-down and less costly version of the NORD-1 with the same general specification but less memory. A substantial number went to CERN, and others to Norwegian sites - including one at Norway's National Centre for Epilepsy, where it processed live EEG signals to detect epileptic seizures automatically. That was pioneering work for 1970.

Specification

Item Value
CPU As NORD-1, simplified
Memory 4K to 16K words of core
Address space 64K words
Control store None - hardwired
Multi-machine Two NORD-2Bs could talk over a data channel and share one I/O system

What was new

  • Cost, rather than capability - this was the NORD-1 made affordable.
  • Used in a 1970 packet-switching network built with Siemens for the Norwegian Air Force Supply Service.

Sources

  • Primary: none held. A NORD-2B Hardware Manual (Dec 1970) and I/O System manual (March 1971) exist in the Tingo collection - see ../OCR-WANTED.md
