Emax

SD cards and Transflash with PC Card adapter.

But I have also used older, actual CF in testing in the past.
There is a database of known working Part #s on the group.

But basically, if you get a blue label SanDisk for example, it will be a
slower speed.
Like This:

I haven't had any problems with Sandisk....

Thx,
Ted
