It is just an LC PDS NIC card, I'm afraid. Farallon probably contracted the design and manufacture. Assante may have designed it in house. Wherever it was designed, you should assume that the designers tried to do a good job.

There are half a dozen other brands that you might recognise. I use a Sonic for the LC PDS NIC because I know that it works and flies. One gotcha is to use an early card in an LC III or later.
