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
