Turbo mode on CASIOs

[xerxes]

Thanks, it was interesting to read. I've modified many devices, but the CASIO PB-1000/2000C was the only one, without having any kind
of complications with the interfaces or the baud rates, regardless of the CPU clock. Another worth mentioning device is the CASIO PB-770,
because it can be accelerated extremly up to factor 5, with a power consumption increase of less than 50% only, if I remember correctly.
