NORD-10/S
The NORD-10/S was a 16-bit medium scale general purpose computer system[1] made by Norsk Data, introduced in 1975. It was a follow up to NORD-10 and introduced cache, paging, and other miscellaneous improvements.
Memory
Memory size may vary from 1K to 256K 16-bit words. Both read-only and read/write memories may be used.
Maximum virtual memory address space is 128 Kbytes.
Maximum physical memory address space is 512 Kbytes.[1]
Interrupt System
16 priority interrupt levels each with 8 registers.[1]
Bootstrap loaders
The NORD-10/S has bootstrap loaders for both mass storage and character oriented devices[1]. Three different load formats are standard:
- octal format load
- binary format load
- mass storage load
Custom Instructions
The NORD-10/S provides up to 1024 customer-specified instructions. These instructions are micro-programmed in a programmable read-only memory, which is added onto the standard read-only memory.[1]
