** Amiga firmware (and alternative standard legacy PS/2 PC firmware) can be found in account downloads area after purchase**

1. Connect a USB cable to the Raspberry Pi Pico board (mounted on the conversion kit PCB) and hold down the BOOTSEL button whilst plugging it into a Linux/Mac/Windows PC. Once connected, release the button.
2. A new Mass Storage Device will appear on your computer called "RPI-RP2". Copy the "usb2ami-0.4.0.uf2" firmware file to this drive.
3. The RPI-RP2 Mass Storage Device drive will now disappear, meaning the firmware is installed. The USB cable can be unplugged from the PCB board and your computer.
4. Carefully - using a plastic guitar plectrum, credit card or other non-marking tool - ease the outer casing from the Amiga mechanical USB keyboard, sliding your tool around the case gently until it comes apart.
5. Remove the Caps Lock, Tab and upper left Q/A keycaps to reveal a screw. Remove the 7 and 4 Numpad keycaps to reveal a second screw. Unscrew both screws and carefully turn over the keyboard PCB.
6. Use a small screwdriver to push the cable connector plug out from the keyboard PCB - be patient, easing a little down each side slit and in the middle of the plug until it pops out easily without excessive force.
7. Have a good look at the supplied photos within the firmware ZIP file (see website account downloads section) to familiarise yourself with the conversion adaptor and where the connectors will go.
8. Remove the USB cable from the keyboard case by unscrewing the two screws, taking out the plastic retainer and remove the connector plug and cable through the case hole. Feed the new grey conversion kit cable through the hole instead, allow some cable slack and relocate the plastic retainer and screws. Tighten everything back in place - connect the plug into the bottom socket of the conversion kit PCB.
9. Connect the multi-coloured 5-wired plug from the top socket of the conversion kit PCB to the keyboard, and tuck this additional controller PCB into the keyboard case cavity so that the two sockets are either side of the internal ridge (see included photo for best position within the case).
10. Check that the supplied clear insulation stickers are blocking any unwanted electrical contact between the PCBs and put the keyboard back together. Plug into your Amiga keyboard socket and enjoy a very nice typing experience!
