    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

    -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.

    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.
