A ND-100 full size crate Roger's collection, that was donated from Gandalf.

It is an empty crate, without power supply or anything, this will be a machine thats used for testing.
System will be mounted in my half height rack together with my normal PC:s.


The system is in the care of Roger and is located in a storage in Umeå, Sweden.

Power Supply







  • Take lots of measurements of crate, until fully documented, possibly a 3D model.
  • Dissassemble, clean and reinstall backplane, CPU & MMU Connector.
  • Document and install cards.
  • Have a frontpanel, but plan to bodge together something smaller, modern and suitable for a testing system after going through it.
  • Adjust cards and get everything set up correctly with IO areas etc.
  • Aquire and install suitable power solution.
  • First power up of CPU, test of system.
