- I don't know where you came up with that notation, but in any parts catalog
- I've ever used, all D-subminiature connectors are referenced as DB connectors,
- where the number following indicates the number of pins. That is typically
- followed by a "P" or an "S" to indicate male or female, but in any case,
- the Apple uses a DB-9 for the game port, a DB-25 (on the //e) for the serial
- port, a DB-25 for the SCSI port, and I believe a DB-15 for the RGB monitor and
- a DB-19 for the Smartport.
-
- (If there was a different letter designation for each type, then there's be no
- need for the number of pins to follow. And the highest DB is apparently a
- DB-37 (always an odd number of pins!). Now there are other connectors with
- the same trapezoidal outline but more than two rows of pins. Those connectors
- have different designations. (An example would be an IBM VGA monitor connector.)
