And IBM 360s aren't the only systems that
don't use ASCII. Also
370s, 390s, and the z/Series right up to the current cutting-edge
systems.
Of course, ben might be forgiven had he protested that those are all
members of the same family from the same manufacturer. Similarly, he
might protest Amdahl, Hitachi, and Fujitsu clones.
A better example would be the SDS (later Xerox) Sigma 7, 9, and 6,
which used 8-bit EBCDIC, even though they were completely incompatible
to the 360 line WRT instruction set architecture.
