We continue our look at building a joystick, after breaking down how they work in the last part now we take a look at the initial design.
We don’t have any joysticks for our RX-78 computers, we could build an adaptor to use another style of controller but what about if we just build one from scratch?
The Bandai RX-78 uses a proprietary joystick port with an 8 pin din. This din should be a 2-3-3 layout with all pins symmetrical. It also makes use of two ground connections, Ground 1 provides Fire, Left and Up when connected to the relevant pins and Ground 2 provides Right and Down.
