Sharp electronic organizers with the IC card slot (Wizard OZ/IQ/PA/PI series)

[Akuji]

Japanese organizer Sharp PA-S1/S1s is not only the last model from the PA series and the cheapest one at the time of introduction (more than twice cheaper than the flagship PA-9500). It's also one of the most widespread Sharp organizer models with the IC card slot. It was introduced in 1991 and re-introduced in 1994 as PA-S1s modification and remained in production until at least 1999, outliving the whole Zaurus/PI series.

PA-S1 is essentially a stripped-down version of PA-8800, though feature-wise, they are(?) identical.





Besides PA-S1, another model, PA-T1, was introduced at the same time. It had a slightly different design and twice the memory but was short-lived.



Finally, let's compare PA-S1 and PA-S1s:













When I got the PA-S1s pictured above (produced in April 1999), a custom IC card based on the stock Basic card PA-7C18 (that's the one that had to be programmed using the PC) was held inside. Unfortunately, the custom app (which stored winning combinations from some Japanese lottery) is gone due to the dead battery. However, what's interesting about this card is that it was produced in December 1997, making PA-7C18 (one of?) the most long-living Japanese IC cards (Sharp introduced it in 1989):
