For my own morbid curiosity, and because it came up on another mailing
list I'm on [1], what machines commercially avaialble were sign magnitude
and one's complement?
A table of what computers had what numeric representation is one of
those things
that should have been done, but never has. Now that bitsavers has a
reasonable collection
of technical/programming manuals, it might even be possible.
http://quadibloc.com/comp/cpint.htm
has some information, but it isn't really in any sort of tabular form.
AFAIK, the PDP-1 was the only DEC 1's compliment
machine that shipped.
I had also heard that 1's compliment never caught on in short word length
machines because of the difficulty dealing with multi-word arithmetic.
