+# The most basic ringtone included in TI's TCS211 delivery was apparently
+# intended to consist of alternating 800 Hz and 900 Hz tones, although
+# the actual output was a continuous 99 Hz tone as a result of interface
+# mismatch between the BZ_Tone() driver function and the tone generation
+# tables.
+#
+# In 2016 we made FC Magnetite emit actual 800 Hz and 900 Hz tones,
+# or rather the closest approximations to these two frequencies that
+# can be produced in BU mode - see ring.buz example.  In 2021 we are
+# looking into the possibility of switching from BU mode to PWT mode;
+# the present melody file is a test of how the closest PWT counterpart
+# to 800/900 Hz would sound.
