TI 99
Now for the finally (Courtesy of Tap), for all you people who have heard
that you can blue box with a TI-99, look no more, here is the way to do it:
Here is what The new England Archivist got when he tested:
What he wanted: What he got:
--------------- ------------
110 110.0 (the lowest possible frequency)
697 699.1
700 699.1
852 853.9
900 902.1
941 940.0
1000 998.7
1100 1096.7
1200 1202.8
1209 1202.8
1210 1215.9
1300 1300.7
1336 1331.6
1477 1471.8
1500 1491.5
1633 1645.0
1700 1694.9
2000 1997.9
2200 2193.4
2600 2601.4
3200 3995.0
44,733 32,286.6 (the highest possible)
These sounds are generated by a call sound routine, the call sound routine
taked about 32 milliseconds to get going. Since the pulses for a fuzz (red)
box are as so, we can do the following:
Quarter: 35ms on 35 off 5x. then by leaving a 34ms space between the
pulses we can execute the following program:.
10 FOR I=1 TO 5
20 CALL SOUND (35,1700,0,2200,0)
30 NEXT I
The 35 is the duration in ms, 1700 and 2200 are the mf frequencies and the
zeros are the volume for each tone. (0 is the loudest, 30 is the quietest).
For auto-dialing a duration of about 100ms seemed to work well. I could go
into detail on this and quote The New england Archivist but maybe not much
interest is shown, if it is write to:
