Project MikroMikko: Introduction

I've come across an old Nokia MikroMikko 4 m310 laptop. Released in 1989 with a 10" display, Intel i386, 8MB ram and 20MB of hard-drive.

The internals were already dead, so I decided to try to build something more modern into it. This series of posts will describe my journey.

Mapping the keyboard

First part of the project is to get the keyboard running. I started to connect all the wires and then map out which column/row was pointing to which keys.

Frood RP2040 Pro Micro Controller

After that I did some research on which controller I'd like to run. I decided on the Frood RP2040 Pro from 42.Keebs since it had enough I/O to handle all 22 connections.

Then I got started on the software for the controller. It runs QMK and you can find the keyboard code on my GitHub.

For the next step I've ordered a 10.5" 1920x1280 IPS display running on USB-C. My next post will be when that arrives and is mounted.
