| Type, Precision, Input mode |
Scientific, 10 BCD digits, exponent ±99,
Algebraic.
The command DEFDBL switches to double precision in RUN mode. This mode
offers 20 digits of precision. The exponent range is still ±99. |
| Programmable |
Yes, BASIC interpreter. The unit is pretty fast
and outperforms even the HP-28S but not the HP-48G or HP-49G.

| Comment |
The PC-E500 is rather fast and its graphical
display makes entering BASIC programs pretty comfortable.
It was later replaced by the PC-E500S.
It is rather tricky to find out about the available memory. Use FRE0 and FRE1 to get the free space for
programs and variables. Use INIT "E:"
to clear all the files from the RAM disk, then DSKF "E:" to see the free space on
the RAM disk. For the PC-E500S FRE0 returns 52886 and DSKF "E:" returns
201216, in total 254102 bytes. So 8042 bytes are used internally. Files
can hold programs or data.
The PC-E500 comes with a sliding cover lid that can be put on the back
of the unit while working with it. The PC-E500S is equipped with a
hinged cover that can be removed.
The keyboard layouts are identical.
