3Com EtherLink III 3C509B-TPO

The 3Com EtherLink III 3C509B-TPO is family of the EtherLink III network cards of 3Com. This version is a 16 bit ISA card with RJ-45 UTP connector.

I use this card with my Commodore Amiga 2000 with the A2286 BridgeBoard solution.

The settings shown via 3C5X9CFG.exe on the bridgeboard.

I prefer to change the transceiver type to RJ-45 and optimization DOS Client. Full Duplex had no major effect on the performance.

TcpSpeed shows 261 kB/s with half duplex and 269 kB/s with full duplex.

I use RoadShow TCP/IP for my Amigas.
