Shangji SJ-560
Brief History
One of the most interesting programmable clones built into the Sharp EL-506H housing. It differs from the standard versions, that its manufacturer rearranged the buttons into a more illogical system than the original, and also swapped the color of the yellow [2ndF] and red [ON/C] keys. In other respects, it is identical to a similar type of Levis presented here.
