ZX Spectrum Internal Kempston
I wanted to add an internal Kempston joystick port to my Sinclair ZX Spectrum Plus, but all the boards I found to make were for external ones via the expansion port, so I decided to make one myself.
The 8 pin header that goes to the DSUB-9 is wired as:
Pin 1: Up
Pin 2: Ground
Pin 3: Down
Pin 4: Action 1
Pin 5: Left
Pin 6: Action 2
Pin 7: Right
Pin 8: +5V
