Model H

This conversion kit allows you to replace your IBM Model M's original internal controller board with a modern USB board. This aims to match the footprint of the original controller and plugs into the original keyboard matrix, but exposes a USB port through the original SDL connector.

Thanks to QMK, the keyboard is fully programmable. It ships with a DFU-style bootloader, which can be programmed over USB.

Features​

  • Non-destructive upgrade - just swap the boards
  • Native USB (with type B connector), no adapter required
  • Doesn't require original controller
  • STM32 ARM Processor @ 72MHz with 64kb flash
  • Remappable keys (using QMK configurator)
  • Uses open source QMK firmare
  • Open source hardware
  • Reprogrammable through USB or ARM SWD
  • Lower power (50 mA typical)
  • Genuine "TE Connectivity Trio-mate" connectors, as used on the original Model M

Compatibility​

The Model H comes in two variants to match different internal connectors. Please check to make sure you order the right one.
