    I have always thought that PCMCIA used ISA-like bus timing and
    frequencies, which would make PCMCIA's maximum bandwidth somewhere
    around 5 MBytes/sec.  This would appear to preclude being able
    to get good performance out of a 100Base-T PCMCIA ethernet card.
    (verses a PCI 100BaseT card, where PCI has 130MBytes/sec of 
    available bandwiddh).
