Brand: CASIO
Model: SF-5580
Type: Organiser
Picture: CASIO SF-5580
Batteries: AAA x 2 + CR 2032 x 1 (memory backup)
Lifetime: Introduced: unknown
Terminated: unknown
Notes: This is a big and heavy organiser with quite a lot of functions, 128KB of memory, a backlit display and even a game (Poker).

The calculator part has a nice separate keyboard layout to the right of the display for easy access.

The keyboard has soft rubber keys and has a good feel to it.

The organiser can be connected to other units and to a computer as well, using a special link cable.


This organiser can be hooked up to a PC using a PC-link cable and PC-link software (available from CASIO, but there are also third-party versions around on the net). The schematics for the link cable can be found on the net as well. I've cached two versions (version 1 and version 2) that are technically practically identical.
