These days a Unix and Linux geek, but I used to work with a Nord-10/S system back in 1982. From 1983 and until about 1986 I worked with real-time systems on ND-100, after that also ND-500, and ND-5000 systems as soon as they became available. The latter systems (first ND-550 and later ND-5500/5700) were deployed at ESA (the European Space Agency) from 1988 to approximately 1995 (when we replaced them with Silicon Graphics systems), where they were used for reception and processing of data from the ERS-1 satellite, and also the ERS-2 satellite in the final year. ERS-1 was launched in 1991 but ESA did fully manned 24/7 simulation-data operations on the first deployed system (ND plus VAX) for two years until launch.. how does that compare to your regular testing regime? :-)

I used to have several sets of what must have been close to every manual Norsk Data ever produced, but unfortunately everything somehow got thrown away at some point, except for a few documents. I also have lots of CCT backup tapes (although some of them are probably quite degraded by now), and I once wrote a tool to read backup-system format tapes on an SGI system, but unfortunately I only copied a couple of tapes back then when I still had a CCT tape drive.

All of which goes to show that despite the best of intentions information loss does continue to happen..

(oh, and I'm also writing my own ND500(x) and ND100 emulators.. the latter just so I can use assembler-500.prog to generate test programs for the former)

Edit: Updating the timeline a bit as and when my memory recall improves.

Update: The activity seems to be a bit low these last few months, I guess we all happened to be busy with other things at the same time. I do however have some updates planned which I will add in the not-too-far future. TArntsen 14:29, 25 February 2010 (UTC)
