EAI Model 180

YEAR: 1970
ITEM: Analog Computer
COMPANY: Electronic Associated Incorporated
COUNTRY: USA
IN OUR COLLECTION: Yes

Electronic Associates Model 180 was manufactured in 1970 and is called a hybrid computer. The device is equipped with IC's from the first generation (DTL-technology). The calculation circuit is plugged with cables on the front panel. The cycle time from the analog part can be set to less than 10ms. With that parameter, an equation will be solved at least 100 times per second. So you can watch the output with a simple oscilloscope.
