Used for a few months when I was fixing my old PowerMac 9500/150 to get drivers off the internet for it, then boxed it up and put on shelf. Works for the old school macs pre-G3's that only came with 10 base T ethernet ports. Even System 8.5. The drivers were always a problem for the older macs and this is fully compatible. Speeds up network and internet speeds. Also works for PC's.
Comes with driver floppy's and in original box.
