PHILIPS SBC 1701

Description

Brand:	PHILIPS
Model:	SBC 1701 "Junior Slide Rule"
Type:	Almost scientific calculator
Picture:
Batteries:	186 x 2 (LR 43)
Lifetime:	Introduced: unknown Terminated: unknown
Notes:	Not entirely sure how to classify this, it’s not quite a scientific calculator but it’s not a basic calculator either because it has squares, reciprocals, π and brackets. This calculator is functionally equivalent to the PHILIPS SBC 155 (which has a very annoying key-press beep). Next to the four basic functions it has a memory, percentages, some scientific functions and even brackets (one level deep). It also has a "π"-key but lacks the trigonometric functions. The constant π however can still be very useful for calculations upon circles and spheres and their derivatives.
