What is the oldest x86 processor that is still supported by a modern Linux kernel in present time?

If you have not read the previous post (Part 1) on this subject, I encourage you but it is not mandatory to do so before reading this post. I’ll still go through the fundamentals in this post. If you just want to see the raw technical details, the schematic and code of this project have been open-sourced here.

The Covox Speech Thing (CST) was a sound card released in 1986 by Covox, Inc to enable computers with parallel ports to have sound capability. Unlike modern machines, proper sound support was not a given on computers in that era and the Soundblaster by Creative has yet to be released.

I’m part of this voluntary social initiative called Repair Kopitiam (RK) started by the social enterprise Sustainable Living Lab. On a monthly basis, we teach Singapore residents how to repair their household electrical appliances, fabrics and furniture. Our volunteers are called repair coaches. This initiative is similar to Repair Cafes which originated in Europe. My area of speciality is of course in the electrical appliance department.

I design Printed Circuit Boards (PCBs) as my part of my job. I also have some PCB projects outside of work with my most famous project among my peers being my PCB name card.

I can’t count how many times I have received business cards only for me to forget about them shortly afterwards. I’m sure I’m not the only one that feel this way when you get a card from someone. For the technical-oriented, you can go directly to my Github link on this project.

Since I started dabbling with hardware like the Arduino, I have always wondered what it would seem like to integrate it with clothing (materials) but did not find the urge to learn.
