USB NeXT Keyboard With an Arduino Micro

coop0030 writes "Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware: pre PS/2 and definitely pre-USB. That means you can't just plug the keyboard into a PS/2 port (even though it looks similar). There is no existing adapters for sale, and no code out there for getting these working, so we spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between."

Re:waste

congratulations on devoting your time & money on doing something useless, thanks for sharing!

They're using a keyboard they like, where previously they could not. And in the abstract, they found a problem and solved it... which is reason enough for a hobby project.

Now go away, troll.

When things lasted

[girlintraining]

Back in the 90s, a company called Northgate Computer Systems, based out of Minnesota, ranked right up there in terms of marketshare, etc as Dell, HP, etc. They had several government contracts which were exceptionally lucrative. They also made keyboards that everyone at the time lusted for because they were super-reliable, very comfortable to use, and quiet despite the snappiness of the keys. You simply couldn't find a better keyboard. Everything was looking great for them, until senior management made a series of horrible and totally avoidable blunders and within a year the company tanked. The one thing to survive the company's demise was their patents on keyboards -- bought out by a company called Avant Stellar (if memory serves). They charge a fortune for their keyboards, and they aren't as reliable as those old ones are.

I can understand why these guys decided to hack together a microcontroller assembly to get it working on modern hardware: human interface equipment back in that day and age was built to last forever. It could even survive contact with 5 year olds, as my keyboard frequently crashed onto concrete floors, was pissed on by animals, and crushed by falling monitors (remember: Back in the day, a 19" monitor weighed a good 50 pounds). Things that would kill today's keyboards dead, it simply brushed off as a non-event.

I wish things were built like that today, rather than this planned obsolesence bullsh*t. There's some things in this industry that just don't change: The power cord, the mouse, the keyboard, and the cases. Build those things to last guys. Really.

Re:ADB

[Misagon]

Not all NeXT keyboards talked ADB, but rather some proprietary NeXT protocol.

The commercial USB-to-ADB adapters, such as the Belkin iMate are not that easy to come by.
The best option might just be to use a small microcontroller board and load it up with custom firmware.

Most keyboard hackers use the Teensy instead of an Arduino, but the boards have more similarities than differences.
You can find open source ADB adapter firmware made for the Teensy over on the Geekhack.org forum. It was made by a guy with the handle "Hasu".
