The A1200 supplies +5V to the PCMCIA-card power supply line. I do to recall that the PCMCIA-specification includes support for both +5V and +3.3V cards, but I think most manufactors of PCMCIA-cards makes them compatible with both voltages - to make to cards work in all possible configurations. All modern PCMCIA-cards I have tried has atleast worked in the PCMCIA-slot of the A1200.
