From the project

Modern, low-cost 10/100 Ethernet for the Macintosh SE and SE/30

Modern, low-cost 10/100 Ethernet for the Macintosh SE and SE/30.

It's an unfortunate reality of retrocomputing that, as time goes on, original hardware only ever becomes more scarce, and usually more expensive.

While PDS ethernet cards are certainly not scarce yet, the collector appeal of Compact Macs means that cards are in high demand, with consequent high prices. As of this writing (October 2023), the going eBay rate for them seems to be of the order of $US 150-200, which is a bit steep for those of us who remember finding them in electronics-recycler dollar bins.
