|Type, Precision, Input mode||Scientific, 10 BCD digits, exponent ±99, Algebraic|
|Programmable||Yes, keystrokes. After exchanging batteries the program memory may be filled with garbage that makes programming impossible! Use "MODE 3 INV MAC" to clear all memory.|
|Performance Index||10. This is surprisingly fast! The HP-15C and HP-41 which which were introduced around the same time only reached performance indices of around 2.6!|
|Memory||Memory shared between program and variables. Use
." to change configuration. Adjustable between 22 register/512 program
and 88 register/32 program steps. One register can store 8 program
Use "MODE .." to see the current configuration. In total approx. 688
Up to 10 different programs. "Synthetic Programming", see also HP-41.
Permanent memory. See manual pg.26.
|Display||11 digits, 5x7 pixel black&white LCD, shared between mantissa and sign. Additional 3 digit 7 segment exponent with one digit reserved for the exponent sign. Contrast not adjustable.|
|Special features||Uses a somewhat strange rounding scheme with 12 digits of internal precision. See manual chapter 2-14, pg. 62.|
|Original Pricing, Production||March 1981 - 1989 or later, list price 29500
1981 one Yen corresponded to approx. 0.005 € so the list price was
Other sources mention introduction Jan 1984 at a price of 198 DM. Maybe that's the introduction date and price in Europe. In 1984 one Yen valued approx. 0.012 DM so the price would have been about 16500 Yen. See Oanda.
Yet other sources indicate availability of the fx-602P in Germany by 1982.
|Batteries||2x large button sized cells|
|Dimensions||Length 14.3cm, Width 7.4cm, Height 1.1cm|

|Comment||A calculator with cult status! Lots of
be found on the web. Its main advantages are the high-contrast dot LCD
(compare this with the HP-41!) and
fact that program instructions are displayed with their normal names
than by cryptic key codes. This makes program editing extremely simple.
Available peripherals: Printer FP-10, cassette interface FA-1 and FA-2 and others.
