| 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
"MODE
." to change configuration. Adjustable between 22 register/512 program
steps
and 88 register/32 program steps. One register can store 8 program
steps.
Use "MODE .." to see the current configuration. In total approx. 688
bytes.
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
Yen. In
1981 one Yen corresponded to approx. 0.005 € so the list price was
about
150€.
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. |

| Comment |
A calculator with cult status! Lots of
information can
be found on the web. Its main advantages are the high-contrast dot LCD
display
(compare this with the HP-41!) and
the
fact that program instructions are displayed with their normal names
rather
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. |
