Still accurate Dec 2018 build, but haven't tried the coordinates. Imagine my frustration reading on the wiki and being told there were 8 of them...and only finding 7 that you can pick up.

So apparently the wiki included the broken tablet as one of them after all. All that time wasted looking for an 8th intact tablet. Oh well.
