Labels

SYSTEM 9883.21238
FLOPPY: 187-3784
STREAMER: 229-1282
DISK: 228-1940

The disk itself has label '228-319' though, so it is likely that this is a replacement/upgrade disk. The ND 9883 models are also known as T9, and like the T17 model they were originally spec'ed with 125MB disks. But this one has a 170MB disk as well as an additional terminal board, an Ethernet II board, and an HDLC board (so that all positions are now in use in this particular system). In that sense this T9 system has been upgraded to a T17 system (due to the extra terminal board), with larger disk and extra communication.

CPU

This system has an ND110/II (110 version 2) CPU, with 48-bit floating point hardware.

Operating system version

Currently unknown

TODO

  • Image the SCSI disk before attempting a boot

The disk, if working, should contain a version of SINTRAN III. But the system password is presumably unknown, so in addition to getting a backup of the disk, imaging it will also get access to the password.

  • Check the power supply condition, start with the test measuring points
