    The EL-9000 is the first graphic calculator from Sharp. It was certainly designed to counter Casio's pionneer effort in this area, yet it offered a screen half the size of Casio's flagship model, the FX-7000G.
    I've first heard about the EL-9000 in high-school, when it was released, as a class mate had one and was very proud of it (France was acquired to Casio's cause at the time).
    Since then, i had a weird memory about it : the sequence for drawing a function's graph seemed a bit awkward. On the Casio machines i was used to, launching any calculation or command (like drawing a graph) was done by entering the expression to execute/calculate, then pressing the "EXE" key, which is exactly like the "ENTER" key on computers.
    In my memory, drawing a graph on the EL-9000 required the following sequence : press the "GRAPH" key to display to graphing command, then enter the function, then press the "DRAW" key to request the graph calculation and drawing!
    A dedicated key just to execute the function graph command! So i grew up with this memory, and as time passed, i started believing the memory could not be accurate.
    A few years later, i found an EL-9000 for sale in a second-hand shop, and missed the chance to buy it. It had disappeared from the store when i came back, and even the store itself disappeared a few months later. Thenks to the internet, i eventually did not miss the second chance i had to buy an EL-9000, and here it is!
    I have thus been able to test it, and check if my memory was accurate : it is!! I have not done any more test for now, tho, so i couldn't say whether the DRAW key is used only to execute the GRAPH command (well then, why not a dedicated execution key for every command, as they were at it?! :) ) or also has another use.
