The Lost Treasures of Infocom CD (Activision, 1992)

Disc-specific material for archiving the Lost Treasures volume 1 CD-ROM (DISK.ID: “LTOICD / 1.0 / Disk 1”, mastered 1992-05-26). No disc content lives in this folder - only identification records, listings, notes.

A single 8 MB ISO 9660 data track, volume INFOCOM, with Apple ISO extensions carrying both the MAC and PC trees - not a hybrid, not separate per-platform discs. Redump has no Lost Treasures entry, so checksums.txt stands as the reference for this pressing.

Contents

File What it is
disc-info.txt Captured drutil and diskutil output
lost-treasures-1-1992.ls.txt Recursive listing of the ISO volume
notes.md Per-disc findings
versions.md Release/serial table for every title, both platforms
checksums.txt Reference hashes for a full dump

Archiving your own copy

  1. Insert the disc; it may take macOS a while to enumerate (retry diskutil list). Confirm one session, one data track, 3895 blocks.

  2. Unmount and dump (seconds, at this size):

    diskutil unmountDisk /dev/diskN
dd if=/dev/rdiskN of=~/Desktop/ltoi1-full-2352.bin bs=2352 count=3895 status=progress
python3 ../../scripts/raw2user.py ~/Desktop/ltoi1-full-2352.bin ~/Desktop/ltoi1-data.iso
  3. Compare the printed hashes against checksums.txt.

  4. Do not copy files off the mounted volume - macOS cannot open the Mac side’s fork-bearing files. Extract from the image instead, which restores resource forks, Finder metadata and dates:

    python3 ../../scripts/appleiso.py ~/Desktop/ltoi1-data.iso ~/Desktop/ltoi1-extracted

Keep the raw .bin as the archival artifact and never modify it.
