NO. 27 NOVEMBER 1974- ~ Yes, after 6 montEs in the pits we're backl Cur unannounced vacation took place for several reasons the main one bemg a shortage of help and a surplus of work. By now we h~ve sold alot of back i~ssues & the mcome has helped to put us solidly in the black. We will try to come out-jairty reg~larly from now on, but th~s depends also on reader contr~butions & printing costs. We are also planning a 1975 Conven- tion and need ideas for the convention from everyone. Possibly contests and exhibits and such. Please write to us if you've got saggestions. In addition, we wi}1 be having techr~cal seminars as al~rays. If you are wen-versed in any phase of phrea~ing covered in TAP or otherwise, please get in teuch with us to teach at the convention. Dear TAP, Checking the guide to Sub~ersive Organizations and Publications (lIouse document 398) I noticed the absence of TAP or YIPL-Ihen I noticed th" date was 1961. Did you make the new list? Anyway, tell your readers that it's illeg~l to re- move the dialing instruction plate on payphones tbelow ~) 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 5/8r' down. Not onty is it ~egal, but if someone were ~Q acciden~lly pake the end of a paperclip throngh the hole, it would do all sorts of terrible things l~e releasing al1 the money chey had ~ust put in to make a ior~ dis~nce call, preventing them from supporting the wonder- ful phone company. (Note- drill wilJ "ut through cast iron case, though r~ot steel lock or coin box -NEW YORK- -And the d~ ing instructi:on pla~e could be put back in, obscuring the hole and allowing nefarious indi~nduals to cor~tinue their plunderlng-TAP. Dear TAP' On a recent trip to Paris I was able to m~ke free calls to any point in the U. S. (except Hawaii) and Europe i~om a speeia1 yellow public telephone booth situated al1 over Paris c~ed "Interurbain". Ihe only catch was that the called party had to be muted othenvise a lond tone makes con~ersation impos- sible. As you know7the m~te prevents supervision, on oversaas trunks this is accomplishod by sending 2400 Hz to the ~lling party C. O., indicating that the n~lled par~ has answered. It is the lack of the 2400 lIz tone which prevents the loud bloc~ng tone from coming on the Paris phone. W~t for dial tone, d;~ 19, wait for a second dia1 tone, then dia1 1 + area code + nurnber. I tried. to oEf a 800 or 555 number, but you can't r9;?1 them nor odY any number for that matter with an SF. I'm not sure, but you might be ~ble to do this from other European cities. I believe tbat the black box is in- ternational, sirce most Europaan telephone systems are still step or crosstar. -NE:W YCRK- ~ _ '~: -1--- x L~si+- UP FROM THE PITS! NEW BLUE BOX INFO We've gotten feeiback on the New Blue Box Cir- cuit (Issue 26). ~ne problem of the circuit is that all the diodes for one frequency must be matched. The Mctorola Silicon dual diode MSD 6150 (co~rn~r~ anode) saves P C board space and is a matched pair. 25˝ each in- 100 quantity. Tf re~lar diodes are to be used, use only silicoa. Though we said germa~um diodes are ok, they usu~y ha~re too much leakage current and the pots will cross-affect each other. In fact, you can eliminate the hassle and match- ing of diodes altogether by using double-pole push- bottons. Polypaks sells a $6. 88 General Telept~one Data en~y keyboard with 10 buttons. Yourll need 2 more DP3T and a SPSI. for 2600, but you~ sa~re money on diades. Ihe same 10 trimpots are n$ed. And keep the wiring to the po~; and switches go~d and secare electrically. A loose cormection is a changing frequency. We also ha~re an unchecked report that eliminating diodes with double pole switches makos the requlator unnecessary. Dear TAP, As for picking Medeco and Keso locks you can for~ get iL Medeco is a sidebar type of lock like the Briggs and Stratton loc~cs G. M. uses in their cars. Locksmi~s usually use codes for auto locks as they can't pick them. A more efflc~ent method for vending machines would be to use an awl & 5 lb. hammer to make a hole in the sheet me~ of the cabinet and then-a n~bbling tool (for electronic con- struction) to enlarge the hole enough to.reach in and disengage ~e lock cylinder from the locking bolts. The m~bler can be bought at T~f~yette or Radio Shack but may not cut through ~1 thicknesses of machine doors. -COLORAD~ Dear TAP, Accordirig- to the N. E.
