If you have been using computers since the early 90s or even before, you probably have couple of these DIN keyboards lying around.
Here’s a DIY that will show you how to solder on a PS/2 style cable to your old DIN keyboard so you can re-use it again.
This instructable is for anyone out there with a perfectly good older style din 5 keyboard that they just can’t seem to throw away. With a little work you can save something from the land fill. Sure you could just buy an adapter cable but that wouldn’t exactly be recycling.
