This is my favourite calculator ever !
I bought it on the 26.01.1983, I still have it and
it still works very well ! With this calculator I have the following still
working accessories:
- QUAD-Memory (256 extra register = 2240 program steps)
- X-Function module (more alphanumeric function)
- Time module (Time and more)
- Wand ( picture
)
Here some other nice picture of this calculator:

HP-41 Cardreader
You could also connect a card reader to the HP-41.
You can also see a module for the HP-41.

Here you see two HP-41 connected via HP-IL (IL means Interface Loop) to some
disc-drives.

CASIO FX-602 P

This is my 2nd CASIO calculator. I bought it on
28.05.1982. The main difference to the FX-501 P is that it's memory has 512
programsteps and that you can use alphanumeric characters. Sadly I don't
have it anymore ! I lost it at Hölter, Gladbeck (Germany).

TI-30

I started with this calculator - no programsteps but with
a display that 'eats' batteries..
