[DuoList] Re: CompactFlash: is 8MB/sec read 1.2MB/sec write fast enough? (Gene Osburn)

[Gary F. Daught]

Thanks Gene. This gives me a sense of where I should be heading. Now,  
can you direct me to a source for a 16-bit pcmcia CompactFlash  
adapter? Newegg.com has CardBus adapters but I couldn't find a 16-bit  
version.
