Transform your gaming experience on classic systems with our Precision AutoFire Joystick Upgrade -- professionally engineered for the ultimate in comfort, performance, and hardware safety:

Rock‑Solid Compatibility

• Plug‑and‑play support for Commodore C64, C128, VIC‑20, Atari ST, and MSX series computers

• Standard DE‑9 (aka DB9) joystick port wiring -- no adapters, no hacks

Ergonomic Design & Controls

• Super‑comfortable, contoured joystick with silky‑smooth 360° motion

• Button A: Up/Jump (mapped from D-Pad Up, your choice as both methods work)

• Button B: Fire

• Button C: Adjustable AutoFire

Precision AutoFire, Your Way

• Adjustable fire‑rate from 4 Hz to 22 Hz via a precision potentiometer hidden in the rear

• Clean duty cycle (~45% to ~55%) ensures reliable, consistent rapid‑fire performance in every session

• Default factory‑set at 12 Hz -- ideal for most titles, but easily tuned for any game or calibration utility

Built‑in Hardware Protection

• All buttons routed through small‑signal diodes to isolate your MOS6526 (CIA) or equivalent port chip from keyboard‑matrix signals -- prevents back‑feed damage when typing and gaming simultaneously

• AutoFire driven by a transistor switch (not directly tied to the internal 555 timer), ensuring low‑current, fail‑safe operation that can't harm your vintage hardware

Premium Modifications, Ready to Ship

• Genuine HyperKin GN6 controllers -- disassembled, precision‑modified, and re‑sealed in the original packaging

• Controllers are brand‑new, pristine, and fully tested; packaging may show minor handling marks from repackaging or original shipping

• Rear‑panel access hole for easy rate adjustment -- just a small Phillips screwdriver (precision or jeweler's) and you're set
