I'm looking at an image that says:
NARROW SCSI: DB 25-pin connector

What does the DB mean? Not Database, not decibals, but something mysterious!

Weird... I've never asked the question either, but I do know the D is just the shape of the connector. I have no idea what the B stands for.

[...]The "D" orginally described the shape of the housing. The second letter : A, B, C, D, or E originally specified the size of the housing where the "E" is used somewhat like it's used as a drawing size (i.e., smaller then a "D"). [...]

Hey Thantos what was your Google query?

So "D" is the shape of the SCSI connector and "B" is the size type.
