Those of us who've used older mainframes (such as the PDP-10) remember "byte" being a synonym for "bit field" and a byte could be any number of bits, typically from 1 to 36 (on a 36-bit-wide machine). 7-bit and 9-bit bytes were quite common on such machines.
PDP being a 'main franme'? Baby mainframe perhaps when compared to Honeywell's (later Bull's) Level 66? Level 66 had 36 bit words which could be used as 6 BCD characters or 4 ASCII characters.
The PDP-11 and microcomputers used 8-bit bytes, and their popularity meant most people using computers at home or in small businesses assumed that that was the only size a byte could be.
Those *were* the days.
