Picture: Radio Shack EC-490
Batteries: Build-in accu
Lifetime: Introduced: 1974
Terminated: unknown
Notes: This is Radio Shack’s version of the Rockwell 63R.

It has a build-in battery pack, and I did not dare try to put power to it. I do not know if the calculator works, and I therefore can not tell anything about how it works unfortunately.

What I can tell however is how beautiful this calculator looks and feels. It looks like a beautiful luxurious jewel. Beautiful. It has slightly slanted keys, and it is a Scientific Calculator. It feels like something right out of Star Trek and well thought out.


A power adapter.
