Another collecting success

On the past Sunday I purchased a mint condition Casio fx-7000G, the first graphing calculator, with a mint condition user's manual for four dollars at the local Salvation Army thrift store. My original one, which was purchased directly from Casio at the time the device came on the market, had developed that sort of dark bloom in the display which made it hard to read.
