The big reason IBM picked eight over six with the S/360 (and yes,
there was a fight over this), was that in the big scheme of things,
eight and four bit chunks are more memory efficient than six bit
Kind of really bad timing on DEC's part, setting up the whole 36 bit
line just as IBM set up everything to 32. But then, they would not
have known. Bad luck.
