Well that's what I said (cause frankly, I didn't want a costly CF chip in my system ... nor did I really want to take space for it) ... but they rattled off a couple of other common formats and said anything was possible. > Probably not a lot of money selling little $10 adapters to the rather > small pool of embedded developers who aren't: > (a) smart enough to choose real embedded chipsets with big-flash support > built in, or Aw > (b) smart enough to realize how easy paging is and design it in > themselves. Big Aw .. Ron, did you hear what he said about you? ;-) Design's not too bad ... manufacture is ugly. If you've already got a tested product, you're at the cheap end of the process.
