I have the Bionic Blue one, since that one is very popular in my school. Not sure if mine has the faster flash, but I guess it depends on the serial. I don't want to take apart my calculator though, I fear I might screw it up somehow
You can definitely tell if yours has the faster flash without taking it apart. Try timing graphing the function in my video; it'll either be ~4-5 seconds or 11+ seconds.
Or you can look at the hardware revision if its M or N (N being the latest revision currently), its got the faster flash. If its any of the following revisions, it doesn't.
prototypes, pre-A, A0, A, B, B0, B1, C, D, E, F, I, J, L
