Type:	Programmable scientific calculator
Picture:
Batteries:	LR43 x 2
Lifetime:	Introduced: unknown Terminated: unknown
Notes:	Small key-programmable calculator by PHILIPS. This calculator has two programming memories. It has two statistical modes and also the ability to perform hexadecimal and octal operations (no binary mode). Some peculiarities: Inverse operations are not marked on the keyboard, but some keys do have them. For example, pressing INV x² performs the square root. The INV key, by the way, is the unmarked top-left key . The calculator has Constant Memory, and the current mode of the calculator is also retained over a power cycle. To switch the calculator between angle systems, press INV +/−. This is not apparent from the keyboard. To get the constant π press INV EXP. Also not apparent from the keyboard. I have no idea what the brown A→B key does. A big thank you to J. Rovers for this donation to the museum.
