I too looked at wikipedia, and it seems historically incomplete to me. 
In particular, I looked for 'high order ascii', which, when I was 
working with Basic Four in the '70's, is what they used.  Essentially, 
the high order bit was set for all characters to make 8A a line feed, 
etc.  Still the same 0..127 characters, but not really an extended ascii 
which is where wikipedia forwards you to.

I remember having to strap the eighth bit high when I reused the older 
line printers to get them to work.
