In this video I show how to make an adapter so these common DB9 style joysticks can be connected to a modern PC via USB

Can I Make My Own 3D Printed Retro Joystick?

In this video I attempt to 3D print and build my own retro-style joystick for my Amiga. With slightly different wiring it would also work on many other systems.

How Floppy Disk Copy Protection Worked

In this video I'll take a look at some of the physical copy protection methods used to prevent disk duplicates from working. This is far from a comprehensive list, but these are some of the most common and most interesting. Play with the Simulator
