Philips - SBC 1745 N


Brand: Philips
Model: SBC 1745 N
Type: Programmable scientific calculator
Batteries: LR43 x 2
Lifetime: Introduced: unknown
Terminated: unknown
Notes: The only similarity between this SBC 1745 N and its predecessor the Philips SBC 1745 is the type designation. And the fact that it can store two programs. Other than that it's a completely different calculator.

The first thing that struck me when I first saw this calculator is the keyboard layout. It very much reminds me of the layout of the TI-68.

This is a two-program key-programmable calculator with many scientific functions. The calculator has statistical functions, the ability to use hexadecimal and octal (but no binary) systems. The calculator has a regular memory "M" but also six separate memories accessed using the "STO" and "RCL" keys in combination with a numerical selection from 1 to 6 (e.g. "RCL" "6").

Also present are conversion functions. To convert 0 oC to oF simply press "0", "INV", "←m", "oF↔oC".

Programming functions include conditional branching and halting.

The calculator has constant memory and remembers the mode it was in when switched off.

A big thank you to J. Rovers for this donation to the museum.
