No, you are out of luck. You bought a totally different type of card.

PC Cards (and that is the correct name, "PCMCIA" should not be used)
come in two electrical types:

1. 16-bit
2. 32-bit (aka "Cardbus")

Machines that support cardbus also support 16-bit, but machines made
before about 1998 do not support cardbus, only 16-bit.

In addition to these two electrical varieties, they also potentially
come in 3 thicknesses, called Type I, Type II and Type III.

Express Bus cards are a totally different animal altogether. They are
not a "type of" PC Card, they are the successor to PC Cards. Note that
Express Bus cards come in two very different physical formats, one looks
like a stick of gum, the other is "L" shaped.

Electrically:

16-bit PC Cards are the laptop equivalent of ISA bus cards
32-bit PC Cards are the laptop equivalent of PCI cards
Express Bus cards are the laptop equivalent of PCI Express cards

In my view, Dell, HP and Compaq were far too quick to drop PC Card
support. Toshiba did this much better: Most of their current models
have one PC Card slot and one Express Bus card slot.

There are no adapters for going from any of the cards to any other type
of cards.
