Ok, the extended KL10 wasn't released until around 1978.

The char type is 9 bits by default.  There is also support for an
8-bit char type.  With four 8-bit chars in a word, the four least
signifiant bits are unused.

No, I'm not that sinister.  If there was a Linux port, I would have
told you already.  Anyway, we need to finish the GCC port first.
