Background

• Origin Systemso Richard Garriott

• Wing Commandero Chris Roberts

• C I C (Combat Information Center)o Ben Lesnick

Page 4: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Scope and Content

36 Digital Data Storage Tapes

Scope and Content

But what's on them?

Page 6: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Hardware

Page 7: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

Research

• Manual pages

• Published material (print and online)

• Online Forums, most critical becauseo It provided directions o Problem workaroundso Practical advice on issueso BUT, not complete or reliable

Breaking Dracula

Page 8: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

The setup

• Challenges in creating a valid connectiono New card and cable

• Challenges in getting the computer to communicate with the driveo Loading the st driver moduleo Loading other moduleso Finding out which drive is correct

Page 9: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

Testing the setup

1. Created test content

2. Wrote content to a spare tape

3. Tested extraction/image commands on the tape

Page 10: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

• Imaging the tapes: sudo dcfldd if=/dev/st0 of=CIC_tape_#.img hash=md5 hashlog=CIC_tape_#.md5

• Results:

Page 11: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

Imaging the tapes: Attempt 2

• Added optionso sudo dd if /dev/st0 of=CIC_tape_#.img

bs=512 ibs= 512 obs=512 count=1 conv=sync,noerror,notrunc

• Mixed successo Produced images with mass to them, but which were

unreadable.

Page 12: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

Further imaging attempts:

• John Filo's program

Page 13: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Process

• At Alex North-Keyes's request, we extracted the first KB of one of the images we had created for him to analyze. o Discovered that the tape contains a POSIX tape

archive

Page 14: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Analyzing the Partial Images

• tar tvf and tar xvfo tar tvf lists the contents of the file o tar xvf extracts the contents

However, this command risks overwriting files in the same directory.

Page 15: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Analyzing the Partial Images

• less CIC_firstkb.img

Page 16: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Analyzing the Partial Images

• od CIC_firstkb.img

Page 17: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Analyzing the Partial Images

• strings CIC_firstkb.img

Communication with Stakeholders

An important part of our process

Who were the stakeholders?

• Zach Vowell of the Briscoe

• The donor, Ben Lesnick of the CIC site

Resources?

• Alex North-Keys

• John Filo

Communication with Stakeholders

What do we know about the tapes? Part 1

Ben Lesnick - the Donor

• Provided us with contextual information about the provenance of the tapes

• Connected us with the primary source of outside help, Alex North-Keys

Page 20: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Communication with Stakeholders

What do we know about the tapes? Part 2

Alex North-Keys

• Person responsible for setting up the system used to create content

• Familiar with how the tapes were created and under what system

• Expert at command line in Linux/Unix and provided multiple options to try that we did not realize on our own

• Came in to try to retrieve content

Page 21: Brian Thomas, Aditi Worcester, Austin Hixson, Samantha Bruner.

Achievements

• Learned a lot of commands

• Gained firsthand experience with the challenges of working with legacy media

• Discovered the creating environment and the format of at least one tape

• Made contacts with experts in the field and consulted with creatorso Ben Lesnicko Alex North-Keyes o John Filo

Moving Forward

- IRIX

• Put Alex in contact with Zach Vowell so that the project can move forward

- Maintain contact with Briscoe Center

- Interview Alex
