The game as originally envisaged placed the three balls as they were locked in holes on a slowly rotating ring around the Deadworld. When the third ball was locked, they were released by a mechanical arm and dropped onto the playfield. This was how it worked in the original software ROM. The problem arose if the arm - or the magnet it contained - failed to work.

This would mean there was no way to release the balls, so the software was changed to only lock the third ball on the ring - the first two sailed past the ring entrance and became "virtual" locks instead. In addition, the ring was changed so the holes became slots. That way, if a ball erroneously ends up on the ring, as it turns, the ball will simply fall off. In a home environment though, the potential for the arm to fail is minimised so wouldn`t it be nice to restore the functionality and make the ball lock work as originally intended I had previously looked on the rec. games. pinball newsgroup to see if anyone had been able to restore the Deadworld, but no one could find the original ROM. Then in October of last year I saw that The Shoot `M Again team ” had uploaded the Rom to the Internet Pinball Database. Originally the prototype Judge Dredd had an opto switch near the entrance to the left ramp (switch 32), later this switch was moved up the ramp and changed number to switch 67. The next step was to try to convert switch 67 back to 32 (switch 67 was not used on the production L_1 rom). Opto switches consist of a transmitter and receiver and need a separate opto board on the Judge Dredd pinball. In order to make the switch number change I needed to use a spare opto switch (65). In the modification switch 65 became column 3 and 67 was linked to row 2 to make 67 become 32. The next task was to make the new locking ring...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
