ND-100 Satellite 14.16796

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

TODO

• Some basic cleaning as the system has been standing since the 90's Done
• Document all serial and model numbers on devices.Done
• 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: Tried to get ASYNC terminals to work. Unable to find any way to do loopback test with valid results. I might need to re-configure to RS-232 as it may be Current-Loop. Maybe card is defect?

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
