The Zork Anthology (Activision, 1994)

Disc-specific material for archiving this CD-ROM. No disc content lives in this folder - only identification records, listings, notes, and disc-specific utilities.

Unlike the hybrid compilations, this is a plain ISO 9660 disc (one Mode 1 track, no HFS side), so modern macOS mounts it by double-click. The catch is different: it is an installer-based disc. The five classic games are not present as files; they live inside ZORKANTH.RED, an Activision installer archive unpacked by the DOS INSTALL.EXE. See notes.md for the format details.

Contents

File What it is
disc-info.txt Captured drutil and diskutil output: TOC, block count, slice layout
zork-anthology-1994.ls.txt Recursive listing of the mounted ISO volume
notes.md Per-disc findings
checksums.txt Reference hashes for a full dump, checked against Redump

Archiving your own copy

  1. Insert the disc; it mounts as ZORK_ANTHOLOGY. Confirm it matches disc-info.txt: one session, one Mode 1 data track, 120295 blocks.

  2. Unmount and dump the whole disc as raw sectors (no sudo needed):

    diskutil unmountDisk /dev/diskN
dd if=/dev/rdiskN of=~/Desktop/za-full-2352.bin bs=2352 count=120295 status=progress

  3. Convert to user data, which also verifies sector structure and prints hashes:

    python3 ../../scripts/raw2user.py ~/Desktop/za-full-2352.bin ~/Desktop/za-full-user.img
  4. Compare the printed hashes against checksums.txt.
  5. The user-data image is a mountable ISO; hdiutil attach -readonly za-full-user.img or use it directly in DOSBox with imgmount d za-full-user.img -t iso.

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