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:
