Product code: Xonex Vintage outlet Calculator ECL-81iii ECL81III Tested and Working 1973 HTF READ
Xonex Vintage Calculator ECL-81iii ECL81III Tested Working Hard to Find!!! Vintage 1973. There was some corrosion in the battery compartment when I bought it, but I managed to clean it up. My initial test showed it wasn't working, but after a little more work on it, I got it going! Also, I tried using a generic 6 volt adaptor to see if it works work via electricity - but just shows some errors on the screen. So for your best bet, I'd stick with using it outlet via battery power.
