This actually happened years ago. Recently, they've decided to adopt the
ultimate kludge. They've dropped all the 60-bit word and 6-bit character
nonsense and now are using 64-bit words and 8-bit bytes (not to mention
using the ASCII character set in their operating system :-). Oh yeah,
their new architecture is also a twos-complement one.
