PVD, what systems need it

[iR0b0t]

'Acorn Archimedes' -- I don't have any
'Microsoft Xbox' -- I don't have any
'Namco / Sega / Nintendo Triforce GD-ROM' -- Triforce = Gamecube, can't see any PVDs inside.
'Palm' -- I don't have any, but these are PC/Win discs with palm soft installers, as I understand, so, most likely, yes.
'Sega Chihiro GD-ROM' -- I don't have any
'Sega Dreamcast GD-ROM' -- yes, but every session has its own PVD, I don't know, whether they always match or not. Same for the multisessional IBM PC discs, btw.
'Sega Lindbergh' -- I don't have any.
'Sega Naomi 2 GD-ROM' -- I don't have any, same as the next one?
'Sega Naomi GD-ROM' -- yes, same as normal DC GD-ROMs
'Sharp X68000' -- I don't have any
'Tao iKTV' -- I don't have any
