There's > no mention of whether it was running UNIX. That one was a C implementation under GCOS. There was another 9-bit one for the PDP-10 (not using Unix). There was a 4x9 bit version of Unix for the Univac 1100 series, which ran Unix as a guest system over the native EXEC OS. The most exotic version was the BBN C-machine, which had 20-bit words, 10-bit bytes. Dennis
