DIY joystick for the BBC Micro – part 2

In the first part I described the interface between two RJ45 Ethernet sockets and the BBC Micro’s analogue port. The idea behind using RJ45 connectors is that you can use any old Ethernet cable to connect the joysticks. But as these are homemade joysticks, they’ll need RJ45 sockets of their own into which one can plug the other end of… Read more »
