Radio Shack EC-4027
No question about it; the EC-4027 calculator is none other but the Sharp EL-5020 in disguise. Not exactly a surprise, given that all Radio Shack calculators are OEM versions of popular models from manufacturers like Casio, Sharp, or Texas Instruments. However, sometimes it's surprisingly difficult to find the original model. Not in this case, however; since I already had an EL-5020 in my possession, it was easy to tell that there was no functional difference between the two machines.
