SIC 1570 Intermediate Electrical Engineer

{Description in preparation}

Here is a scan done by the ISRM of the Scientific Instrument Co. slide rules promotional brochure-poster. (I have this same poster in my collection but I have not scanned it yet, it is big...sorry). In this brochure you can see also the prices of models commercialized by Scientific Instruments Co. in the early 1960's. The cost of the 1510 was $25.50. approximately $ 220.00 in 2020, while the 5510 model cost was $ 13.50, approximately $ 114.00 now.

The next operations can be calculated with a precision of two-three decimals with the 1570
