No it doesn?t. The 360/65 was still a 32-bit processor (as defined by the ISA). It makes
no difference what the width to memory was. Wider memory is only to improve the bandwidth

?confusing? because the width to memory is 256-bits.

Sorry, thanks for playing but
Actually half of a WORD is a BYTE, whatever the numerical length is.
Ready for this,half of a BYTE is a NIBBLE.
Well, no. On 32-bit machines such as
IBM 360, VAX, etc. half a 32-bit word is a halfword,
the fullword is equal to FOUR bytes. On a 360/65 and above, the memory word was 64 bits,
or a double-word, so half that was a fullword. Just makes it more confusing.
