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:
