ASCII Stick II Turbo for Family Computer

From Videogame Interface Wiki

ASCII's sequel to the ASCII Stick for Family Computer, which's a bit more comfortable to use as there're no sharp corners to dig into your palms, but it's not as pretty. It adds variable speed turbo fire (like the ASCII Stick Engine for PC Engine), and audio ports so you can use a cassette recorder to save/load data without needing a Family BASIC Keyboard. It retains the pass-through port and adds a switch to assign it as player 1 or 2, and there's also a slider to set if it reads 4 or 8 directions off the stick.

There's also a version for the MSX.

It's a little unintuitive how you assign rapid fire: you have to hold the button you want to add this too (can be any button, even a joystick direction or start (slow-motion)), then press the 'TURBO' button.
