A ND-100 Satellite model 14 machine in RHansen's collection,
Hardware
Hardware in the machine is described in this section.
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
Labels
On the devices
FLOPPY: ND 187-3464 STREAMER: ND 150-001021 TDC 3300 Series, TDC_3309 (partno ? 326112) (serialno ? 564323) DISK: Micropolis 1325 (S/N:6082010769 P/N:900525-09-BA) 74 MB formatted (https://www.micropolis.com/support/hard-drives/1325)
On the front of the cabinet (behind the front door)
- printed label above tape streamer / floppy drive
LOGNR 1064
- 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
- Document all serial and model numbers on devices.
- 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
- 2024-10-03: Trying to identify signals from the HDLC output connector using a scope to find clock signal, but was rather unsuccessful.. maybe I am not expected to see clean digital clock signals - all I could find was somewhat analog. I really need to find some description for where where TX +/- and send clock +/- is supposed to be on the connectors.
- 2024-10-03: Booted SINTRAN from the MFM HDD emulator. Managed to get MegaLink card to work with XMSG subsystem, but I first had to reconfigure the device address so it became MegaLink #1 (was #5 in the other machine)
- 2024-10-03: There was one free slot in the machine, marked HDLC. Moved over a MegaLink card from my other machine, and now I could boot from floppy. Ran test programs and things seeem ok. Still some strange results in CONFIGURE first time I run it.
- 2024-10-03: Tried to boot from floppy, but system just hung. Seemed like INTERRUPT or IDENT signals somehow got lost.
- 2024-10-03: Opened the keylock and managed to get power to the system. Inserted back all the cards, one by one, and no smoke signals. Got console access.
- 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
