Model: SBC 1701 "Junior Slide Rule"
Type: Almost scientific calculator
Picture: PHILIPS SBC 1701
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.
