| (...) Depends on what you call 'recent' :-) The DEC PDP-8 had 12-bit words with 6-bit bytes, if I recall correctly. There were also computers with 36-bit words containing six 6-bit bytes in one word (DEC 10/20?), or three 12-bit bytes. The DataSaab (...) (21 years ago, 30-Jun-03, to lugnet.robotics)
