I see others have cited the IBM 7030 and Telefunken TR 4 as examples of 
early computers that used (or at least were explicitly engineered to use) 
8 bit character encoding. However, as far as I can tell both of those 
machines were word addressable machines, and their word sizes were 
different and much larger than their character sizes. Was there any 
pre-System/360 example of a computer that stored characters in 8 bits 
*and* offered 8 bit memory addressing? (Or 6 and 6, or 7 and 7?) For that 
matter, are there any still extant digital computer processors that (only) 
have word addressable memory and don't have 8 bit byte addressable memory?

History evidently judges that particular System/360 design decision as 
wise or at least not unwise.
