Probably

Is it still available?
You can probably pick up cheap cards on ebay, but I doubt they're being made anymore.

I think the last time we talked about this, someone said that using the PC card for floating point didn't work very well because (with a StrongARM) it didn't provide any speed boost.

Of course if you were to write a program that uses the PC card as a proper second processor (rather than a simple FPU) then you'd get much better performance.

Posts: 600 		As Jeffrey says, on a StrongArm, the overheads in calling the card were such that the normal FPEmulator was faster. However, there is SuperFPEm which is a different software FP emulator which is supposed to be faster.
