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.
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.
