 I don't know if I'd call it octal but if you were writing an assembler for
quite a few microcontrollers the opcodes would have a pattern where source
ans destination registers were 0 - 7,

   Octal does persist, sometimes in obscure ways and places.
   It WAS kinda big for awhile - a "big step" better than
   8-bit.
   Alas don't think anymore 12 or 24 bit CPUs are
   gonna be made. Might still have a place for some
   higher-end microcontrollers - hell, I think Epson
   still makes FOUR-bit microcontrollers (looked at
   the sheet for one once, insanely capable).
   Hmmm ... 256 of those 4-bitters running
   parallel - that'd be a fun project :-)
