This post has really not too much to do with TwinCAT, at least not directly. Instead, this post will be about a computer that’s close to my heart. So, despite not being directly related to TwinCAT, it’s about the computer which started my interest in software engineering, and ultimately led me to where I am today, therefore this post. The Commodore 64 was my first computer. The first version was released the same year I was born. Rewind the time back to the mid 80s, and this was the computer that everyone had back in those days. It was a fantastic machine back then. 1MHz clock frequency, amazing video-graphics, a whopping 64K of user RAM (hence the name) and fantastic sound (provided by the SID-chip). Despite the limited performance when judged by today standards, people were doing amazing stuff with it. The game and demo-scene was flourishing.
