Original use of hexadecimal[edit]

The article states that hexadecimal using U-Z for the additional digits originated in 1956. It was actually in use before that. The earliest use that I'm aware of was on the SWAC computer, which used hexadecimal (with letters U-Z) in 1950. It had a 36-bit word (plus sign and breakpoint bits)used to hold 4 8-bit addresses (it had 256 words of memory) and a 4-bit op code.
