Just a FYI - as this is in Amiga - assume you mean the Amiga RGB and floppy connector - yes ?
Well that connector is not a D-sub connector - its just (AFAIK) called D-shell . The confusion arises from the name of the VGA 15-pin connector - which IS called 15-pin D-sub. Thats to distinguish it from the old 15-pin D connector, which has the same pin spacing/density as 23-pin D, 9-pin D, 25-pin D etc.
Mentioning it cos it could well affect on-line searches ....
