But as far as I know the interface of the SMD drives and CMD drives were
identical. At least the Norsk Data ND10 used them both on the same
interface in the computer end.

Hello,
I also was searching about a clear SMD specification years ago, I found
something in disk documentation from CDC, but doubts remain, because some
disks call the interface SMD, some other CMD, never understood the
difference...
CMD was the name of the division that manufactured the disks, FWIW. Not
heard of CDC calling it anything other than SMD. It was their golden
goose, so though it's not really a spec, reading the specs of any CDC drive
of an equivalent capability as you are looking for is probably what any
standard would contain. The big problem they faced was there wasn't a
second act for them, despite
spending huge amounts on a lot of other products. They continued using
oddball interfaces to try to pull the same stunt and people didn't fall for
it twice.
The closesest that anyone came to challenging them was the Trident
interface, but they crashed and burned anyway.
When did you see something called CMD?
thanks
Jim
