The problem of course is that I've scoured the map quite extensively. 3 intact purple tablets on Mountain Island (land) + 1 broken, 2 underwater similarly in the mountain island area, 1 downstairs in the QEP, and 1 on the Floating Island. 7 intact, 1 broken. The only places online I've found people actually posting exact locations of purple tablets include the broken one as one of the eight. No-one else seems to be willing to actually look for all 8 themselves and confirm the ambiguous number on the wiki.
