Eldorado Electrodata Corp was a company making Computers and electronic instruments, between 196x to 1974. The history is difficult to trace, but by browsing many pages on the internet I was able to find some details about what they were doing.
They were based in Concord, California. They started to make mini computers, such as the EE200
For those of you old enough to remember this, please note the Bootstrap Loader switch !!
The computer was using Core memory in the increment of 4KB (4096 bytes). As the price of one core was $900, this gives us a price of 22 cents per byte.
This would give a price for a 1GB memory card of : 219.7 Million dollars
They also made some measurement instruments, such as Frequency counter.
In the 1970s, as everybody else was making calculators, they tried to release a few products. The calculators were solidly built, such as the Director Two model, and the large display was ideal for a desktop model.
You can still find many of these for sale, and most of them are working fine.
Here is an overview of the models offered by Eldorado Electrodata Corp:
