When designing S/360, it seems that there was a proposed ASCII-8
(eight bit ASCII) that never appeared. (Not just ASCII-7 with an
extra bit added.) IBM never used it, and the PSW bit was reused
to allow virtual addressing in S/370.

Must be some interesting conversion somewhere along the way for
Linux/390, but yes.
