== Pame number system doesn't appear to be base 8 == 

 Going through the article linked as a citation, if you scroll down to the actual words, you'll notice a few things. 
 First, the number 8 does have significance. The word for 9 (nda ntsaw? nda) is made from putting together the words for 8 (nda ntsaw?) and 1 (nda). But that's not enough to say that they have a base 8 number system. 

 The word for 10 isn't made from putting together the words for 8 and 2. 10 gets its own word: seska?ai. 
 The word for 11 isn't made from putting together 8 and 3. It's made from putting together 10 and 1: seska?ai nda 

 Similarly for all the numbers between 10 and 20. 16 is 10 and 6, 19 is 10 and 9, etc. 
 There's no entry on the list for a word meaning 64. A language that uses base 8 obviously would have a separate word for 64. 

 There is a word for 100: nda ntswa?. 
 And 200: nui ntswa? 
 And 300: renhu? ntswa? 

 Unsurprisingly, nda, nui, and renhu? are similar to the words for 1, 2, and 3, respectively. 

 It's not a base 8 language. It's a base 10 language with a special word for 8.
