Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Nord 10/S Computer System

16 page coloured and illustrated sale leaflet with some nice photographs
NORD-10 was a medium-sized general-purpose 16-bit minicomputer designed for multilingual time-sharing applications and for real-time multiprogram systems, produced by Norsk Data. It was introduced in 1973. The later follow up model, NORD-10/S, introduced in 1975, introduced cache, paging, and other miscellaneous improvements.
The CPU had a microprocessor, which was defined in the manual as a portmanteau of "microcode processor" - not to be confused with the then nascent microprocessor. The CPU additionally contained instructions, operator communication, bootstrap loaders, and hardware test programs, that were implemented in a 1K ROM.
The microprocessor also allowed for customer specified instructions to be built in. NORD-10 had a memory management system with hardware paging extending the memory size from 64 to 256K 16-bit words and two independent protecting systems, one acting on each page and one on the mode of instructions. The interrupt system had 16 program levels in hardware, each with its own set of general-purpose registers.

Date : 1973

Creator : Norsk Data
