Hi- Thls may end some of the conblslon about the nu~nber to ~11 whlch glves you a computer-generated volce telling you your phone number: In lIYC there are 4 numbers-They are: 730, 840, 958, 880. One w311 always worktexcept in a few C. Q s) The numbers rotate each month. Other boros may lead or lag 1 month. IAst is for 1973 but I think it will be same next year. -FIH, N-Y- TAP~ You rntght tell Phellovv ~reaks in NYC that there are three different 3-digit nurnbers to dial for flnding out the number you're calling from, and that they are rea- onal. What's more, Pa BeI1 likes to switch 'em now then to confuse us. That's the reasontthey're regir~al} tbat one might work for one area but not another. ~hey are 958,311, and 221. If N, Y. C. telephone subscribers have suspected tbat the number of "additional message units" they're being charged for on their monthly bill is too high, itis probably true. I got it on good authority (a former operator) that NY Tel routinely overcharges customers on ~dditional m. u. 's every month. And they qet a~=y with it since message units are not verifiable, because they are not itemized like toll calls. You have to take their word. The padding takes place not in the computers but in Acconnting, where Pa Bell~s hard- worLing CPA's are under orders to pile on a heap of extra message units because who'll be the wiser? And wLen one complains to the B O. Rep. tbat he keeps track of his calls and couldn't possibly have made so many, we're told that they wiIl'bheck our equipment"- a ruse, a diversionary tactic, because that's not where the shlllduggery is being done. Get it? - H. R. Holdafone- Dear TAP, There existed among the gang back in NJancouver some very sick minds who delighted in setting various parts of a payphone on fire. What they would do is open the phone book up around the middle, pour gasoline on same, placed a peper cup containing a particular mixture in it upon the soaked book and waLk away ln about two min- utes' the book would be a~ame and would parboll the plastic handset into submission and if the booth itself was molded out o! plastic, a cheerful blaze greeted the pigs and other such carbon compaounds. The mix- blre in the cup was about half a heaping teaspoon of Potasstum Permanganate(chemical and hobby stores) and, to be added just before an innocent departure, one drop of glycerine(drugstores for ointment use). This pile of goodies usnally erupts into a white hot ~are capable of igniting almost anything, including gas fumes. The reacLion, by the way, takes from 30 seconds on a hot day with finely gronnd Pot Per to 6 minutes on a cold day with clunky Compound P. Also ideal for quiet little garbage cans at school or may~e even Telco vehicle's gas tank in a small bag- gie or a gas sodden piece of construction ~at you feel is bad for the environment or simply remote & safe ignition of fireworks.

The 2600 wEistle perfector is a 2600 detector similar to existing toll-fraud detectors. The Displayed Red Box is similar to Issue #16's circuit with an improved IC timer, LED lights to demonstrate operation, and a fe~v other improvemenLs. The circult can be used as p~rtable with a few chan~es ~e explain, and is far more reliable than the older cLrcuit. The Dual Tone Oscillator is a circui: for demonstrating signalling ~nes, and can even be uged as a s~mple blue box. The sheets are 15½ each~free if you can't aflord it).
