ND-110 Satellite 988 21251

ND-110 Satellite model 988 with CPU number 21251 is a ND-110 Satellite that once was the property of Kungliga Bostadsstyrelsen and it still got the original installation on the hard disk. It's been fitted with some extra cards and the CPU is replaced with a ND-120 CPU. The CPU-number is not changed as the prom with the ID is sitting on the back plane. It booted without any problem.

Configuration
There is a high probability that the cards installed is not what was in it from the beginning. It's been almost filled to the limit and the only thing missing is the HDLC/MEGALINK card.
 * Hard disk : 120 MB Micropolis SCSI disc
 * Floppy : 5.25" floppy
 * Tape : SCSI tape streamer is installed with one tape and is working perfectly.
 * Slot 1 : PIOC/256
 * Slot 2 : ETHERNET IF II
 * Slot 3 : CPU, ND-120CX with 4MByte memory
 * Slot 4 : SCSI / FLOPPY
 * Slot 5 : 2 MBYTE RAM
 * Slot 6 : Unoccupied (HDLC / MEGALINK)
 * Slot 7 : 8 TERM. IF

Operating system
Currently installed and booting SINTRAN III - VSX/500 K

Disk image analysis
This is some notes taken when analyzing the disk image to extract SYSTEM password and other information about the system. Addresses are in bytes and hexadecimal for easier handling by the binary editor. Pointers is addressed in disk blocks of 2048 bytes. 03bf:f800 ..SYSTEM'.........WW.&..¨à¦«..qH..L......ÿ...................... -> password = 0x5757 03bf:f840 ..RT'..............Ò.&..¨ÛTÚ.......w.....ÿ...................... -> password = 0x02d2 03bf:f880 ..SCRATCH'...........&..¦ÚÔ....Ð...®.....ÿ...................... -> password missing 03bf:f8c0 ..FLOPPY-USER'.......&.©¨ÚÄ÷.............ÿ...................... -> password missing 03bf:f900 ..SUPERVISOR'........õ..§.÷ç...°...c.....ÿ...................... -> password missing 03bf:f940 ..UTILITY'...........&.«§$Òt...@.........ÿ...................... -> password missing 03bf:f980 ..NDSYS-11037'.....Ò..ÇÜ¦Øx-...½.........ÿ...................... -> password = 0x02d2 03bf:f9c0 ..ND-OPERATIONS'.....&.­¨.ó!....ð...æ.....ÿ...................... -> password missing 03bf:fa00 ..ND-SPOOL-AREA'.....&.®¦Øx.... .........ÿ...................... -> password missing 03bf:fa40 ..NOTIS'WP'N'........&.°¨«X,...$...$.....ÿ...................... -> password missing 03bf:fa80 ..ERFAR'..............ÎS¥Ð®....d.........ÿ...................... -> password missing 03bf:fac0 ..NOTIS-DS'..........&.²¥Ð®....Ð...t.....ÿ...................... -> password missing 03bf:fb00 ..50LISB''...........b¢Û¥Ð®....d.........ÿ...................... -> password missing 03bf:fb40 ..KJ3D'D'............v.¹¨á.....d.........ÿ...................... -> password missing 03bf:fb80 ..ALMI'X'.............Ô.¨..ß...^...ó............................ -> password missing 03bf:fbc0 ..50BMCH'...............¥Ð®....È.........ÿ...................... -> password missing 03bf:fc00 ..FASTIGHET'..........Ãó¥Ð®....Ü...£.....ÿ...................... -> password missing 03bf:fc40 ..SFD'...............f©'¥Ð®....ô...M.....ÿ...................... -> password missing 03bf:fc80 ..X25-NETWORK'........Åá¥Ð®....¼.........ÿ...................... -> password missing 03bf:fcc0 ..USER-ENVIRONMENT...Å$9¨â½........\.....ÿ...................... -> password missing 03bf:fd00 ..BLANKETTER'.......¥X.°¥Ð®....d.........ÿ...................... -> password missing 03bf:fd40 ..AGMI'I'............v.a¨ÚÜ5...¼...÷............................ -> password missing 03bf:fd80 ..MAHO'.............¥².Ì¨ârÕ...ô...3.....ÿ...................... -> password missing 03bf:fdc0 ..MAMA'S'...........¢Â§0§<Ö¹...d.........ÿ...................... -> password missing 03bf:fe00 ..RAPPORT'..........¥É;Y¥É password missing 03bf:fe40 ..PEAL'E'...........¢Â§.¥<ÒA...d.........ÿ...................... -> password missing 03bf:fe80 ..PROG'.............¢Ð..§.·....d...c.....ÿ...................... -> password missing 03bf:fec0 ..MALL'.............¢ü÷k¥<ÒB...,........5¿...................... -> password missing 03bf:ff00 ..ING3'.............¦...¨vþJ.............ÿ...................... -> password missing 03bf:ff40 ..P50'..............¦..Þ¨Ê»D.............ÿ...................... -> password missing 03bf:ff80 ..1KLJ'.............¦bçæ¨à°(...d...I.....ÿ...................... -> password missing 03bf:ffc0 ..G3DA'.............¦bèÇ¦..Ï...2.........ÿ...................... -> password missing
