On a lighter note, I find it rather humorous that when Sperry, purveyor of 36-bit word machines, and Burroughs, purveyor of 48-bit word (and also bit-variable word-length) machines combined, they managed to pick a catchphrase absolutely antithetical to both product lines. Well, I guess the do base 2 arithmetic, but wait, didn't the Univacs use ones-comp, or was it only classic CDC machines??? -Mike O'Dell

I had to convert a tape of 1's comp 24 bit numbers to 2's comp 36 bits. >CDC machines??? -- bill davidsen (wedu@ge-crd.arpa) {chinet | philabs | sesimo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me

Ones-complement, twos-complement, sign+magnitude, excess-64, etc are integer representations independent of number base. I.e., all the machines you listed are base-2 machines, except perhaps in their handling of floating point mantissas.
