| Type, Input Mode |
Special version for computer science
applications/software
development, Reverse Polish Notation |
| Precision |
Depends on selected word size for integer modes:
up to
64 bits.
In float mode 7 bytes: 10 BCD digits (5 bytes) |
| Programmable |
203 bytes maximum, shared with variable
registers. Numeric
and symbolic labels. Indirect GTO. Maximum 4 subroutine calls. Command
insertion
and deletion
Speed-wise it ranks at the low end of HP calculator performance. Slower
ones are the HP-55 and HP-34C. |
| Performance
Index |
1.3 |
| Memory |
Permanent memory. Number of available registers
depends
on current word width. A float value needs 7 bytes, a 64-bit integer
values
needs 8 bytes. 32 direct addressable register STO/RCL 0 to F, .0 to .F.
Additional
registers must be accessed thru indirect register I. |
| Display |
10 digit 7 segment LCD display plus sign |
| Special features |
Can be operated in floating point, decimal, hex,
octal
and binary mode. Integer and floating point word size is adjustable up
to
64 bits in 1-bit increments. Supports bit masks and bit shifting
operations. |

| Comment |
A unique type of calculator, especially designed
for
software engineers who have to program down to the very register bits
of
their machines. A maximum word size of 64-bit makes it state of the art
even
today (2002). Not much use for an average user though. The programming
model
is very similar to the HP-11C. |
