ok.....here goes....I couldn't find my best file on makin' the red box so I'll have to make my own...oh well about time! ok to start with...some things you will need.... Parts: a radio shack 33-memory dialer (stock # 43-141) a 6.5000 or 6.5536 Mhz crystal (can get from digi-key) some solder and a solder iron INFO: Why a $24.95 33-memory dialer and not the little $15 dialer? Well when you place a quarter in a pay phone it makes 5 distinct sounds (red tones)! If you were using a dialer that didn't have a memory option you couldn't get all 5 of these tones produced by hitting a button...you would have to hit a button 5 times. These tones have to be produced at a certain rate and the 43-141 dialer does a pretty good job at reproducing that rate...so that's why.... Part 1: ok...so you have the dialer? what the hell now? ok take the battery cover off and remove batteries if they are present. There will be two screw in the compartment and two at the top of the dialer...remove all four. Now take a small flat-head screwdriver and pull the body of the dialer apart. I like to start at the bottom where you took out the batteries...there is a section where the screwdriver fits nicely and you can just start prying it apart. alright now its apart and should look something like this: ******************* ******************* * ****** * * _____________ * * ** sp ** *------Wire--- * | Green | * * * eak * * * | Board | * N * * er * *------Wire----* | | * | * ** ** * * | | * W- -E * ****** * * | | * | * * * |XX= | * S * *** * * | | * * * X * *------Wire----* | | * * *** *------Wire----* _____________ * * * * * * * * Batteries * * * * * * * * * ******************* ******************* ok...the wire connect the green board to the speaker and some silver thing, which I have no idea what the function is. The part you want to modify is the XX=, which represent the crystal. This crystal is somewhat cylindrical shaped, silver, and has two prongs soldered to the board. Unsolder the crystal and replace with the 6.5536 or 6.5000, which is about 2 times as big. You might have to place the new crystal in a somewhat different location, I did the following: Original Crystal: New Crystal: The leg of the | | __ Crystal is bent. | | | | The crystal is also | XX= | -- on the opposite side | | || of soldering places | ==_| than the original Thats it...just replace the crystal, essentially anyway you can. Part 2: Now programming the dialer. The * key is the one that produces the correct frequencies. So to program P1 for a quarter turn the dialer on and place switch in store position. Then hit memory, and ***** (* key 5 times), memory again and then P1 or any position you want to store this. A beep will sound confirming the storage. I have P2, and P3 stored as half dollar and dollar. For example: hit memory, *****, pause, *****, memory, P2. That will store the tones for 2 quarters. Remember: * is a nickel ** is a dime ***** is a quarter So program you dialer anyway you want.... ok...now you wan to be cool and have a switch so you can store regular dial tones and red tones.... XX=====--------------| | | |--------------| | | Switch |----|-| | | | | |----|----------------| The crystals will share a common ground and have separate hot wires so that when you switch to one position you have one crystal and the other position will be the other crystal....this SPDT switch can be gotten at Shit Shack (Radio Shack) Thank you for listening...this has been another DINO production.
