Casio CZ/ VZ/ FZ - Pro Series

Sweet math equation!  I did a similar calculation myself last night
and came up with almost the same answer.

The thing is, most Casio keyboards will work form varying degrees of
current and voltage.  For example, I have a Casio MT-68, and the
original adapter for it was 7.5V at 600mA.  I cobbled together an
adapter for it, by splicing a good plug onto a 7.5V at 200mA power supply.

 600mA
-200mA
------
 400mA - That's how much power (current) I'm missing.

Using your sweet equation I find out that I'm missing 400mA.  And yet
it works fabulously.  An MT-68 is not very computery though, and can
run from lower power.  If you lower the power enough it will actually
play quieter, rather than not operate at all (I think).

The CZ-101 needs more current, but I'm guessing it also has a narrower
range of operation.  So the question is really: for people who have
made their own power supplies, do you have any clue about the range of
operation in a CZ-101?

Thanks!
