Description
This full color book is a snapshot in time of 350+ calculators that contributed to the demise of the slide rule industry. Logarithmic-based slide rules were used in engineering, science, commerce, and education for 350 years until the sudden onslaught of the invention of the “electronic slide rule” and other scientific calculators. The death of all the slide rule manufacturers was kicked off by the Hewlett-Packard HP-35 in 1972 and sealed by the Texas Instruments TI-30 single-chip calculator in 1976. If you are a collector of red LED (Light Emitting Diode) or green VFD (Vacuum Fluorescent Display) calculators that called themselves "slide rules," this is a must-have book for you. Except for the black and white advertisements from that period, all the images are in color to accent the beautiful and widely diverse product packaging and keyboard designs. Read more
