ISEC 250 Wood box
Custom wooden case designed to hold the ISEC 250 analog computer. The case measures 17.5 x 9 x 10 inches. The computer that it was designed for measured 16.5 x 7 x 9 inches.
We have only the custom case, not the computer...at least not yet.
The ISEC 250 computer was a single purpose computer...it was designed to assess the risk involved in buying and selling stocks. The Wall Street analyst would enter the latest information on a particular stock along with current market trends and the computer would figure out an answer. The computer had a dial that showed that stock was either a HIGH RISK (in red) or a LOW RISK (in green) or somewhere in between. The ISEC 250 was preloaded with information on over 2,000 stocks.
For more information, see the user manual here.
