Working adapter which I can't use on my Sun Ultra1 170, because it's not compatible. Seen by the PROM and by the OS as present, but can't get drivers to load. Not a big deal, as this belongs in a Sun4M machine anyways!

Boost your vintage SparcStation lunchbox or pizzabox system with 100mbit 100bT ethernet!

Link: to the official Sun FEH / option sheet.

$30 USD + shipping. DM me your address for a post estimate. It will fit in quite a small box so I don't expect shipping to cost much.

Thanks for looking! :D
