1. Obscure commands, part 8

8. BEEP abilities and limitations
Contrary to the manual, BEEP t, f (t = time from 0-10 in seconds), f--
the number of semitones above/below middle C--is not limited to 69 as
the maximum value. To the limit of the computer's precision, the
limit is actually 69.84586091. Minimum value is actually -60 as the
book states. The full 10-second range is not available for higher f
values. The T/S 2068 Technical Manual touches on this a little.
Here are some relevant charts that I compiled:
f Max. t, sec t, sec highest f
------------------------ -------------------
69.84586091 4.437 5.000 67.777
69 4.654 6.000 64.614
68 4.931 7.000 61.961
67 5.224 8.000 59.634
66 5.535 9.000 57.594
65 5.864 10.000 55.777
64 6.213
63 6.582
62 6.973
61 7.388
60 7.827
59 8.293
58 8.786
57 9.309
56 9.862
55 10.449
54 to -60 10.499
Note that 10 seconds is not the absolute maximum time: 10.499 is.
All right, gang, I'd be interested in any additions or comments.
Thanks for your indulgence, and maybe this will spur some discussion.

Hi, Why do you think that those are obscure commands?
They are all (almost) reported in my TC2048 and TC2068 manual.
Less this one about beep (the limit being 69.84586091), but what does this
matters?
Beep 1,69 is almost un-earable...
You can find some real obscure commands in my website:
