A few months ago, I purchased this on Ebay to get an inexpensive ethernet working. I'd seen several tutorials on how to set this up to use the PC bridgeboard with a PC ISA network card for connectivity on the Amiga side.
I never had the opportunity to test it out though as other auction bids yielded all the network cards I needed.
I'm putting the Commodore A2286 and 3COM Etherlink III card up for auction together if someone wants to try it out.
