ScreamingAtTheRadio Posted September 4, 2021 Share Posted September 4, 2021 My Atari 130XE keyboard rebuild project is finally done and I'm excited to share it with you! There's been a number of previous projects to put a modern keyboard on Atari 8-bit computers. I don't think anyone's done it while preserving the original keycaps though (would love to be proven wrong). This is exactly what I did though, by 3D-printing modified stems for Kailh Box Pink switches that take the Atari XE key footprint instead of the Cherry MX cross. Cheap resin printers can print at an amazing 50 micron resolution, which is enough to print very small parts with very fine details. Switch stems are such parts, and must be printed very precisely to reproduce the touch and feel from the original. It took a lot of tinkering to get there, and trying a lot of different resins (in the end, Elegoo black and translucent red were the most reliable), but the keyboard feels absolutely great. What's more, you can't tell the difference from an aesthetic point of view... Check this out: This is built on a new original PCB design, a custom laser-cut steel plate, Kailh Box Pinks and Costar stabilizers. The stabilizer metal parts are also preserved, but the one for the space bar has a diameter that's considerably larger than off-the-shelf Costar stabilizers can handle, so I also 3D printed new ones: I have a video showing the end result in action: All files for this project can be found here: https://github.com/bleroy/3d-junkyard/tree/main/Atari130MX Let me know what you think! 24 2 Quote Link to comment Share on other sites More sharing options...
