ND-5800 Serial number 5800.258 have spent most of it's life in Luleå in the rooms of LUDD, the local computer club. The previous owner was Ragge. I don't know a lot of the previous history of this system but I will do some research in the future.

The system has been used as a card storage so the cards are pushed in wherever there was place. With it came three CPU:s, two smaller ones and one maxed out Samson CPU

Full rack without panels.

The system was given to me in the spring of 2018.

Card cage configuration

ND-100 crate

This list reflects the original configuration as well as the current one. At the moment it's been used to store spare cards so the current configuration doesn't make much sense.

ND-5000 crate

This list shows both the configuration I got the system in and any changes made.

The three ND-5000 family CPU:s

17-19 320002 or 320003 SAMSON CPU type II 3 layers, check the CPU type, hard to see in pictures.
20 Empty
21-23 320003 SAMSON CPU type III 4 layers

Current status

The system resides in the ND-Collection in Umeå. It's operational status isn't known and it is standing in a corner. The card crates have been used as storage space so it needs an overhaul to check that every card is in the right spot as well as checking power supplies.

Plans

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