# DecentXL mechanical keyboard for Atari 600/800XL - ABBUC Hardware Competition
I'd like to submit this new design for your consideration in the 2023 hardware competition.
The DecentXL keyboard is a drop-in replacement keyboard for Atari 600XL and 800XL computers. It is designed for people who need to replace a broken keyboard, or want to upgrade to a modern mechanical keyboard.
The new keyboards exist in two versions: 1. The modern layout that you see in the photo above is entirely new and does not require a donor keyboard. The layout features a narrower space bar, leaving space for a control key to the left and a break key to the right. It has a convenient oversized ISO return key and a wide backspace. Finally, caps is at the same spot as on a PC keyboard, above left shift. 2. The vintage layout requires a donor keyboard, of which it re-uses the caps. It is visually indistinguishable from the original keyboard once assembled.
Both versions feature adjustable backlighting:
This is a high-quality, hand-assembled made-to-order keyboard: • Can be built with any MX-compatible switches for the modern version, Kailh Choc v2 switches or Matias Alps-compatible switches for the vintage version • Anti-ghosting diode on each switch • An aluminium plate rigidifies the assembly and keeps switches perfectly aligned • 3D-printed brackets solidly mount the keyboard to the XL top case • A custom flexible PCB connects the keyboard to the motherboard
## Video I made a 5 minute video presenting the keyboard: https://youtu.be/AVq3QIOBxNM
## Summary Type of device: keyboard Purpose: drop-in replacement Compatible with devices: Atari 600XL, Atari 800XL Available connectors: connects into the original 24 pin connector on the motherboard through a flexible PCB, or the connector can be replaced with a soldered adapter and a standard FFC 26 pin 1mm pitch cable. Power supply: none needed, provided as part of the standard pinout of the motherboard's keyboard connector. Current consumption: depending on brightness setting, 0 to ~100mA.
## Notes: The photos are from my first prototype of the modern version (v1.0), and the final product may differ in a number of ways. For instance, the blank right shift is an error from our key cap provider, not a deliberate design choice. The final product has a legend on all caps. The fabrication files submitted for the contest are version 1.1, integrating all modifications I had to make on the prototype.
