Streaming setting up the mainframe

I want to try something I have never done before. I will stream setting up the mainframe.

Ok, let's try this. Stream for setting up the mainframe is going to be at twitch.tv/mainframedev. I aim to start tomorrow (Sat) at 13:00 CEST / 11:00 Z. It's going to be recorded as well. Tune in and chat with me and my friend soundgoof when we install a mainframe from scratch. — Christian Svensson (@blueCmd) August 9, 2019 As I mentioned it will be recorded and I will post the uploaded videos here after the fact unless something catastrophic happens.

Update: The stream was successful! You can watch the recording here:
