Picked one by one from a mixed channel. Transcript check: both title readers certain; 5 of 5 sampled certain picks confirmed by transcript, none failed. Channel rule: Include only plainly titled restoration parts, OS-install and configuration tutorials (e.g. ISP Series episodes like 'Configuring RADIUS for a dial-up ISP', 'Setting up a retro multi-node BBS on OS/2 Warp', the 'Macintosh Classic II Restoration' parts), and sober technology-history documentaries (e.g. 'EXPANDING THE ETHER: The invention of the network bridge'). Exclude clickbait-titled videos, event vlogs, short power-on teasers, and the watch-along compilation.
