Why not an Emulator? Read on and you will understand. I’ll warn you right away: this method only works where _all_ cards are issued have the same identifier sewn into ROM, and also use a separate conclusion to supply programming voltage. Such cards are still found in vegetable garden Tested on domestically produced machines TMGS-15280 (manufacturer JSC "Telta", Perm) To make a chemulator, the following initial components are required: 1) A person with not very crooked hands. 2) Not working card. Only contact pads are used from it. When wished- You can make a printed circuit board from thin PCB. 3) Empty but serviceable card 4) A card with the nth (you will find out N later) number of units. The chip is removed from a non-working card (the chip itself, contact leave the pads in place!), thin ones are soldered to the contact padswires connected from the other end to the device itself. Device is attached to the place on the map that usually sticks out of the machine when card is inserted (See fig). The device should not interfere with inserting the card. /------------------------------ ----- | ___ |--- D | | < | | | e | | |___| | at 0--- | | a [] <---Switch | | th x--- | Map |--- with | ------------------------------/ ----- Inside the device there are two neatly cut chips (together with contacts, of course) and a two-position switch for 5 groups, switching wires to one or the other chip. One of the chips contains 0 units (empty that is), and the other - exactly as many units as ours The machine eats up in one minute. The switch can be used ready-made, but you can, as we did, strengthen the chips on the slider by placing them under the contacts chip pads have elastic contacts, from standard ISA slots, for example. By moving the slider, you can connect one or another chip to the contacts. Yes, I completely forgot - to the contact to which the programmed voltage is applied.If the voltage is 22 V, it is not only not worth connecting the wire, but it is generally impossible! If you hold the card with the chip towards you and to the left, then this contact will be the second top right (just under the common ground contact). The wires should be thin enough to allow your device to move freely entered and exited the machine (remember Eeyore's ball and pot? All it should be exactly like this - it goes in and out :))) Cover the wires with a wide tape so that they do not dangle or fray. That position switch, in which an empty chip is connected to the output, mark it with “0”. Position, in which a non-empty chip is connected, mark it with an “x”. How to use the device: Set the switch to the "x" position. Insert your device into automatic At the same time, the indicator will display the number of units on your device. that chip. Move the switch to position "0". Now you can dial number and calmly press “reply”. The stupid machine will try to reset the unit tsy from the empty chip you slipped, but there was a zero there, and it will remain there. After that, he will check the result of his redneck actions - there were x units, it became zero, everything was okay - and for one minute of conversation he will give it to you. If you need to talk for more than one minute, wait until the machine will beep about the end of the “paid” period. Take out your device and repeatthe whole operation from the beginning. The machine will assume that you just changed the card. When In the future, the device can be inserted into the machine every minute only for a few seconds at the end of each minute, feeding the machine with new a portion of your “virtual money”. The rest of the time the chemulator can be kept keep it in your pocket so as not to attract the attention of strangers. Now do you understand why you don’t need to connect the programming voltage? If you forget to flip your toggle switch in time, the redneck creature will simply eat units from your non-empty chip. :( when Uprog is disabled, do this the dirty trick won't work :)))) The disadvantage of the method (besides those indicated at the beginning) is that for each tariff zone, the number of units on a non-empty chip must be different. Therefore you need to make several devices for the tariff zones you usually visit call; You can also make a device “with replaceable cartridges”. Have a phun!
