ND-500 Serial 062
ND-500 Serial number 062 was delivered to Studsvik Energiteknik in Nyköping, Sweden, in April 1982. It consisted of a ND-520 cabinet with 1/4 MByte local ND-100 memory and 1/2 MByte multiport memory. It also had a 75 MByte disk and four terminal interfaces. The system was given to me in August 2009.

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. With the system came a lot of binders with the original documentation and software.
Plans
The system will be put in working order some time in the future. First it will be documented.
