Well, I've had issues getting my Farallon card to work.  If I used the Apple supplied MacTCP & AppleTalk software, it doesn't work.  If I use the copies supplied on the Farallon disk, it works.  They're the same version number, too.

I've yet to compare them with ResCompare, maybe Farallon's adds an identifier or something to make it work.  Could be something similar with the DaynaPort.

Also, I'm not aware of a clock chip for IIci.  If it's a 50MHz accelerator, probably an 030 Daystar or something similar.
