6bits was the "byte" size for the PDP-8 (swap acc halves).
9bits was the byte size for the PDP-10, I believe IBM360 and CDC6600
12 bits was link-8, PDP-8 and PDP-12 (likely others).
9/18 the pdp7 (first home of unix).

What computer systems did you have in mind?
9 bit ????
12 bit ???? 9 bit characters, and some that have 12 bit address
spaces but I'm sure
that
if there were indeed, such things as a nine bit or
twelve bit computer,
they'll be mentioned soon enough 8-/
-spc (But I do want to say the PDP-8 was a 12 bit system for some reason
... )

9bits was the byte size for the PDP-10, I believe
IBM360 and CDC6600
Na, the /360 was a plain 8 Bit/Byte machine, but I think you're
right about the CDC. AFAIR there was a Bull machine using 9 Bit Bytes,
and 18 Bit integers.

I don't know about the /360, but the the /370 and
/390 used 8-bit bytes,
32-bit words, and 31-bit (!) addressing.
Well,
/360 16 Bit address
/370 24 Bit address
/390 24 or 31 Bit address
All architectures had 8 Bit Bytes and 32 Bit Registers

/360 24 bit addresses, 8 bit bytes 32 bit registers
Shure that you don't mangle up /360 and /370 ?
The Addresscalculation as Register Field plus 12 Bit offset in the
16 Bit operand field of an instruction was already an extension.

Unrelated to CDCs, there was the 1610 CPU in the
Intellivision that was
10-bit internally.
I've always found it interesting that some documents,
including the Intellivision FAQ, list it as using the GI CP1600 at
500KHz while other documentation, including the Blue Sky Rangers
site, lists it as using the CP1610 at roughtly 900KHz. Supposedly
they are they same other than the differing clock rates. All agree
that the chip had 16bit registers, 16bit data bus and 10bit
instructions.

You sure about the CDC-6600? The complete word length was 60 bits, and I
seem to recall that for the purposes of characters, there were 10 6 bit
characters stored per word.
http://www.scd.ucar.edu/computers/gallery/cdc/6600.html The PPUs were 12
bitters.

the pdp-10 could use 6/7/9 bits for bytes.
