A ND-100 Satellite model 14 machine in RHansen's collection,

Hardware

Hardware in the machine is described in this section.

PCB Cards in the Satellite

Even if its an ND-100 Satellite, it seems it uses the same chassis as the ND-110 Satellite. In this case its the Model 14 chassis.

A sales document with more details for the ND-110 Satellite can be found here http://norsk-data.com/library/libsales/ND-SID019-A1-NO.pdf

Devices

  • Floppy drive : 5 1/4" (potentially 1.2MB)
  • Tape streamer : Tandberg TDC 3309
  • Hard drive : MICROPOLIS 1325 (74 MB) - Unable to read drive/bad sectors. Head stuck, but could get ut unstuck by opening the drive and using a chop-stick like described here [1]

Mounted on Disc-board 1824B

Power Supply

  • Wiener DN 01, 390 W

Connectors

  • Power connector : [2] C16 type C16
  • Power cable [3]
  • Console connector : DB25F

  • Norsk Data ID LABEL at the bottom
CAB./ASSY NO: 1.1
FUNCTION: SATELLITE 14
SYSTEM NO: 16796

TODO

  • Some basic cleaning as the system has been standing since the 90's DoneDone
  • Document all serial and model numbers on devices.DoneDone
  • Image the MFM disk before attempting a boot. Template:Failed Drive unreadable.
    • Heads was stuck, had to "unstuck" them using a chopstick ref https://www.pdp8online.com/rd53/rd53.shtml
    • Using MFM_READ tool and the MFM emulator I tried to dump the disk, but was unsuccessful due to "Bad sectors" on (almost) all cylinders
    • Tested using ND program DISK-MM (DISK Media Maintenance - Version: C03 - 1990-06-11)
      • Connected the drive to another ND machine (ND-110 Compact) to run MFM test programs
      • Reported "NOT ON CYLINDER" when the heads was stuck, but after it changed to "Address mismatch" - sadly no data can be retrieved at this point
      • Doing seek-test shows that the heads move freely across all cylinders. Can see that because the disk is opened, and I can visually inspect the head movements.
  • Check the power supply condition Template:In progress

History

2024-08-18: Tried to image the MFM HDD, but failed - disk unreadable
2024-08-18: Started going through the system, documenting it and basic cleaning in preparation for getting it up.
2024-08-17: System donated to me from Håvard Sten
