The Competition Pro is a legendary joystick from the early 80s created by Kempston Micro Electronics, the same company that produced the Kempston interface for my

beloved ZX Spectrum.

Here is my retro remake of this awesome 80s waggle stick using arcade parts to power the internals.

The main body parts click together quite tightly, so make sure to screw your Sanwa clone

joystick into the housing first.

Joy_QSCP_JSTop is built for a stem/shaft of 37 x 9mm (not inc. screw top)

As there are numerous Sanwa clones of various stem/shaft sizes, you might need to fine tune the joystick top to fit.
