Yes, this has been here before. Back then I replied that, when confronted with the same problem, I simply took a hacksaw to a DB-25 and had a working connector within a minute. Not as fancy, maybe, but just as functional...
Sure, that works for a one-off. Not exactly a good solution though when you are selling a new product. "So, plug the cable into the rough hack-sawed connector on the back of our jankey product".
