Sycard PCCtest 450/460 PC Card (Optional)
The PCCtest 450 and 460 cards (version 1.05) from Sycard Technology are the only recommended
diagnostic tools that test the functionality of the PCMCIA slots using a PCMCIA card. Each is a
Type II PC card that works with test software to exercise PCMCIA functions. (For details, see the
Sycard Technology Web site: http://www.sycard.com).
The PCCtest product contains these components:
PCCtest 450 or 460 (revision 1.05) PC card.
PCCtest 450/460 software disk. (Software updates are available at the Sycard Technology
Web site.)
Configuration headers (PC card/16-bit and CardBus/32-bit) that attach to the card.
You will also need a CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the
Sycard PCMCIA connector.
Use the following tests to check the function of the notebook’s PCMCIA slots. See the Sycard
documentation for details about running the tests.
