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 six classic games are not present as loose files; they live inside ZORKANTH.RED, an Activision installer archive unpacked by the DOS INSTALL.EXE. See notes.md for the container format and versions.md for the exact builds inside it.

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.
