“But wait!” says the well-intentioned blog reader, “this web site over here has DB-19P connectors for sale right now!” They may claim to have them, but trust me, they don’t. It’s very similar to the more familiar DB-9 (old style serial ports) or DB-25, but with a different width to accommodate the different number of pins.
The specific part in question is a D-SUB DB-19 male solder cup connector, sometimes called DB-19P.
I also made several attempts to design a DB-19 substitute using a small PCB and suitably-arranged header pins, but while they more-or-less worked, I wasn’t satisfied with the result. Since then I’ve written a dozen times about the impending DB-19 doomsday. The DB-19 shortage first became obvious to me about a year and a half ago, when a manufacturing error forced me to replace all the DB-19 connectors in a batch of boards, and replacements couldn’t be readily found. It was clear I’d reached the end of the road. My last few product batches included DB-19s from some very obscure international sources. Over the past couple of years, I’ve scrounged what seems like every warehouse and basement on the planet, and bought up nearly the entire world’s remaining supply of new-old-stock DB-19 connectors. I’ve got a disk emulator product called Floppy Emu that attaches to an Apple DB-19 port, so I need a steady supply of these connectors to build my hardware, and that’s a problem. Nobody has made these connectors for decades. If you’ve been reading this blog for any length of time, then you’ve certainly heard me whine and moan about how impossible it is to find the obscure DB-19 disk connector used on vintage Macintosh and Apple II computers (and some NeXT and Atari computers too). This is a happy story about the power of global communication and manufacturing resources in today’s world. Oh man, this is good!
