Hello,

Today I've tried to connect both cards on SE/30 but it doesn't work.  
MacOS 7.5 reports an error about TCP and NetBSD only detects Asante  
and not Farallon.

:(

Anyone knows why? I've read about a guy with 2 devices (vga card and  
accelarator) attached to an Asante card.

Thanks,

	Nuno Teixeira
