This file will get you free accounts for the new 1-900 system being
offered by over 700 BBS's (according to BoardWatch Mag) throughout
the USA.
The TABS system is a 1-900 billing service that BBS's subscribe to
that allows you to call a 900 number and get access to the bbs or
files or whatever the bbs happens to be giving out for the call.
Each call costs $10.00 but shortly there will be $25.00 options
too.
When you call the 900 number, you type in the BBS's phone number as
the "PIN" and a 7 digit number is parcelled out to you for your 10
bucks. This 7 digit number is somehow computed from the board's
PIN. From my experimentation, you can derive the next number valid
number from any existing valid number.
For example, if you know that the number 1234567 was valid at some
point in time, then you can apply this formula to it to derive the
next valid number for that board. If that number is already used,
then you would derive the next number from that number and continue
until you get a number that get's your account.
The only problem with my technique is that you require one valid
number to act as the seed. This is because each board starts out
at some point which I have not been able to discern, but I think it
is based upon the board's phone number. Hopefully by January or
February I will have that nailed.
The steps
1. Known Valid Number: 1234567
2. First, raise by 1/12 1234567 ^ (1/12) = 3.218297753
3. The next number is the first 7 fractional digits : 2182977
To Get Next Valid Number, Repeat Steps 1-3
1. Known Valid Number: 2182977
2. First, raise by 1/12 2182977 ^ (1/12) = 3.374847062
3. The next number is the first 7 fractional digits : 3748470
To Get Next Valid Number, Repeat Steps 1-3
1. Known Valid Number: 3748470
2. First, raise by 1/12 3748470 ^ (1/12) = 3.53037769
3. The next number is the first 7 fractional digits : 5303776
You get the point.
The only problem with my technique is that you require one valid
I have used this technique to get 23 accounts (worth $230.00) in
the 3 weeks I have since I have figured out the iterative formula.
I figure by Jan. 94 I should probably have enough to give to my
friend! The trouble now is finding the boards that subscribe to
tabs.
