Fix Broken Numpad 0 on yacobo IBM Model M (#25742)
I built three of these and was confused as to why my numpad 0 wasn't
working. Eventually, I consulted this website to see the key matrix for
the Model M

https://sharktastica.co.uk/sims/matrix?kb=enhanced

`kp_0` is in the matrix at [0, 12], not [0, 11]. Simple off by one
error. I fixed this, flashed to all my keyboards, and it worked.

yacobo

A replacement qmk-compatible control board for the 101-key Model M keyboards. Inspired by and based on the ModelH by jhawthorn, in comparison this design uses 100% through-hole components, including the widely available STM32F103C8T6 "Blue Pill" development board, for ease of assembly.

  • Keyboard Maintainer: Stephen Edwards
  • Hardware Supported: IBM 101-key Model M with Yacobo replacement control boards.
  • Hardware Availability: Yacobo PCB.

Make example for this keyboard (after setting up your build environment):

make yacobo:default

Flashing example for this keyboard:

make yacobo:default:flash

Bootloader

Enter the bootloader in 3 ways:

  • Bootmagic reset: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
  • Physical reset button: Press the "Reset" button on the Blue Pill daughterboard.
  • Keycode in layout: Press the key mapped to QK_BOOT if it is available
