Carefully re-attach the lid making sure that none of the wires are pinched between the lid and the bottom case, and similarly making sure that none of the wires impinge on the movement of any of the gears or other moving parts.

Test the movement before installing it in the clock. Install a AA battery in the movement and hold the shaft up to your ear. You should be able to hear a distinct ticking that's consistent with the particular pattern of the firmware you've loaded.

Assemble (or re-assemble) the movement in its clock. This step is no different than it would be otherwise with an ordinary movement.

To modify a Quartex Q-80 movement, first obtain the Q-80 variant crazy clock board. If you make the boards yourself, you must get them made with 1mm thickness. 1.6mm, which is the "standard" thickness, won't fit properly.

Pry the lid off the movement. Pull the plastic gear train box out carefully. Do not allow the black square gear retainer to fall off the shaft and take the outside gears with it. Also, don't allow the battery contact prongs to fall out of the bottom of the case.

Place the gear train on your workbench on its back (shaft facing up). Unscrew and set aside the screw holding the battery terminal end of the board down.

Carefully and completely desolder the two coil terminal pins. Watch out for the plastic pins immediately adjacent to the top coil pin. Do not melt or deform them or the board will be very difficult to remove and replace.

Make sure that the two coil pins are completely free from the board and that you can see an "air gap" all the way around each pin.

Holding the pins down with your finger, wiggle the board to insure it's free, then carefully lift it up and off the pins. Your goal is to insure you do not put any upwards tension on either coil pin, lest you break the coil wires attached to them. If those wires break, repairing them is virtually impossible. You can use an ohmmeter to test the continuity. You should see approximately 230 ohms resistance between the two pins.

If you haven't already, program and fuse the crazy clock board. This is easier to do without the coil terminals connected, as they represent a low impedance load on the programmer.

Install the Crazy Clock board in the space formerly occupied by the manufacturer's board. Screw the screw back into place and insure the board is flat against the gear case. Solder the two coil pins to the board.
