I will e-mail a copy to you (or anyone else). The compiler supports it, see cc(1). The laodable device driver comes with UNIX, see /etc/lddrv/fpa.o. You can't get the board because it was canceled due to poor performance (only 50% improvement) It is an expansion board, and the driver uses an F-line emulator to talk to it. >Please help, I am starving for floating point support.

Thanks for any info you can provide. Don't even bother.
