Hello. Regarding VHD, Japanese Wikipedia mentions that a VHD prototype was made for MUSE, but I couldn't find it anywhere on the internet other than Wikipedia. Any information, photos, etc. about this? is there? Thanks. Japanase Wikipedia VHD page:
https://ja.m.wikipedia.org/wiki/VHD

Quote: 来るハイビジョン時代を想定し、MUSE方式によるHi-Vision VHDの開発も日本ビクターと松下電器産業の手で行われていたが、市場に出ることはなかった。

Can't find anything either.

But it does predate Internet so... elusive by nature.

The most "exotic" VHD we found was a PAL prototype Europe (France):

=> Châteaux de la Loire (1985) [900247]

And a dozen or so of AHD releases.
