HP’s got the Primr. What about Sharp, Casio, TI?

Sharp do a free pc emulator for their EL-9950G graphing calculator. search for Sharp EL9950g Simulator. should show up "http://www.sharp-calculators.com/en/id/127-downloads" which should give you all sorts of sharp goodies. windows will warn that it it is not secure, but if you go on anyway it should be ok. I did panic at the start because I forgot to switch the ON button and follow the display instructions. Have fun.
