Gotta use that 10 Gbps fibre-to-the-home broadband for something! But
no, I used a script: archive.org serves range requests, so it fetched
only the volume descriptors, path tables and directory extents of each
image, about half a megabyte per disc, and parsed those. I'm happy to
share the script and the list of images.

Will do, unless Hui would like to take it.
