AFAIK the only processors around that are not two's complement are:
Burroughs processors that have been upgraded by Unisys
CDC 6x00 and Cyber line; no longer in production
DEC System-20 (still used by CompuServe)
GE 600/6000 line, now BULL DPS 8 or some such
Univac 1100 line, now Unisys 2200
All of these have small and declining market shares. I don't know
whether there is an Ada compiler for any of these, but I suspect that
Mr.
Dewar would know. I doubt that there would be an economic incentive to
do
a new compiler for any of them.

As I noted above, the DEC PDP-6/PDP-10 line is not quite dead;
CompuServe
is still using it, although the hardware comes from a third party
vendor.
