RIP Radio Shack EC-4013 Calculator
I got this calculator in high school back in 19something… a long time ago. I used it in calculus, college physics, statistics, last semester’s chemistry class… it was the calculator I grew up on.
A few weeks ago, some of the buttons on the fold-out section stopped working. It’s very sad but calculator microsurgery isn’t a priority.
I have the same calculator!!! I bought it in 1985.
I have the same problem with some buttons on the right side pad.
The quality is excellant!
The problem is with the ribbon connecting left and right side, which is hiden under welded plastic cover. Some of the metal path are broken due to folding and unfolding the cover. I can’t understand the manufacturer’s policy (Sharp?) not to continue production of one of the best scientific calc tools.
It must be a cosmic conspiracy. I just googled Radio Shack EC-4013 because the 3 key has started not registering. The right hand side is fine. I purchase this calculator in 1986, my senior year in high school. It made it all the way to 2012. It has seen me through college, grad school and post doc. Its an old friend that I’m going to miss. Especially the easy metric to US standard conversions.
Mourning a calculator. My sister is right, I’m a nerd.
where is the battery in these things?
i am tired of it blinking out when a shadow goes by…

wle, sorry, dunno. I never had trouble with the battery. On mine, if you covered the solar panel, the display would shut off in like 5 seconds so the battery was more of a small capacitor. It would have to be pretty much so dark that I couldn’t see the display for the solar panel to not power it.
battery is behind the display
very hard to get to
may not be able to reassemble
snaps broke
etc
plus weird size battery
but i did find it :)

without battery, it would revert to HEX and GRAD mode or something weird every time the light went away

Cool! Glad you found it!
