Remember, these raws are historical documents. If you find one, become a seeder. Do not hoard it behind a paywall. The "exclusive" nature of this content should be a source of community preservation, not elitism.
In the original 1979 broadcast, the show featured a distinct "eyecatch" (a 5-second animation) mid-episode with the title Doraemon . Commercial raws preserve the "A-part" to "B-part" transition. If the video cuts straight through without a fade to black, it is an edited version, not a true raw.
If you need this for , consider joining a dedicated anime raw preservation group. Otherwise, the most accessible version of 1979 Doraemon is the DVD box set rips (which are still raw Japanese but lack some TV-only episodes).
