I have an "Amiganet" zorro card by hydra systems up for sale - its the bnc/rj45 connector version, in its original box complete with original floppy disk and manuals. Comes with "hydranexus" software on the disk (as well as standard sanaII ? drivers).
Worked fine with genesis on workbench 3.9 in my A4000 (which I have now sold, hence why card available).
PM me if interested. :-D
