[HaBi 1]    TAP No. 27 - November 1974

TAP No. 27 - November 1974 Yes, after 6 months in the pits we're back! Our unannounced vacation took place for several reasons the main one being a shortage of help and a surplus of work. By now we have sold a lot of back issues & the income has helped to put us solidly in the black. We will try to come out fairly regularly from now on, but this depends also on reader contributions & printing costs. We are also planning a 1975 Convention and need ideas for the convention from everyone. Possibly contests and exhibits and such. Please write to us if you've got suggestions. In addition, we will be having technical seminars as always. If you are well-versed in any phase of phreaking covered in TAP or otherwise, please get in touch with us to teach at the convention. Dear TAP, Checking the guide to Subversive Organizations and Publications (House document 398) I noticed the absence of TAP or YIPL-Then I noticed the date was 1961. Did you make the new list? Anyway, tell your readers that it's illegal to remove the dialing instruction plate on payphones (below dial) if they were planning on using a high carbon bit on a hand drill to drill a hole exactly 2 3/4" to the right and 5/8" down. Not only is it illegal, someone were to accidently poke the end of a paperclip through the hole, it would do all sorts of terrible things like, releasing all the money they had just put in to make a long distance call, preventing them from supporting the wonderful phone company. (Note- drill will cut through cast iron case, though not steel lock or coin box.) -NEW YORK- And the dialing instruction plate could be put back in, obscuring the hole and allowing nefarious individuals to continue their plundering-TAP. Dear TAP, On a recent trip to Paris I was able to make free calls to any point in the U. S. (except Hawaii) and Europe from a special yellow public telephone booth situated all over Paris called "Interurbain". The only catch was that the called party had to be muted otherwise a loud tone makes conversation impossible. As you know, the mute prevents supervision, on overseas trunks this is accomplished by sending 2400 Hz to the calling party C. O. , indicating that the called party has answered. It is the lack of the 2400 Hz tone which prevents the loud blocking tone from coming on the Paris phone. Wait for dial tone, dial 1,9, wait for a second dial tone, then dial 1 + area.code + number. I tried to off a 800 or 555 number, but you can't dial them nor off any number for that matter with an SF. I'm not sure, but you might be able to do this from other European cities. I believe that the black box is international, sirce most European telephone systems are still step or crossbar. -NEW YORK- NEW BLUE BOX INFO We've gotten feedback on the New Blue Box Circuit (Issue 26). One problem of the circuit is that all the diodes for one frequency must be matched. The Motorola Silicon dual diode MSD 6150 (common anode) saves PC board space and is a matched pair. 25c each in 100 quantity. If regular diodes are to be used, use only silicon. Though we said germanium diodes are ok, they usually have too much leakage current and the pots will cross-affect each other. In fact, you can eliminate the hassle and matching of diodes altogether by using double-pole pushbuttons. Polypaks sells a $6.88 General Telephone Data entry keyboard with 10 buttons. You'll need 2 more DPST and a SPST for 2600, but you'll save money on diodes. The same 10 trimpots are used. And keep the wiring to the pots and switches good and secure electrically. A loose connection is a changing frequency. We also have an unchecked report that eliminating diodes with double pole switches makes the regulator unnecessary. Dear TAP, as for picking Medeco and Keso locks you can for get it. Medeco is a sidebar type of lock like the Briggs and Stratton locks G. M. uses in their cars. Locksmiths usually use codes for auto locks as they can't pick them. A more efficient methhod for vending machines would be to use an awl & 5 lb. hammer to make a hole in the sheet metal of the cabinet and then-a nibbling tool (for electronic construction) to enlarge the hole enough to reach in and disengage the lock cylinder from the locking bolts. The nibbler can be bought at Lafayette or Radio Shack but may not cut through all thicknesses of machine doors. -COLORADO Dear TAP, According to the N. E. T. news line, you people are breaking the state law of Mass. when you published the 1975- Credit Card Code. Upon conviction you can be fined $2000 and get a year in the slammer. When I heard this I called the head of Security in Boston with a phoney c.c. number and told him what I was doing. Then I asked him what he was going to do about it. Was he ever pissed off. Yours in conspiracy Stainless-Steel Rat (C) Youth Hot Line Reports, Inc. 1974 Movement qroups may reprint with TAP's address, and please send us a copy of reprinted work.
