You got it mixed up, Louis. It's you who is on the *wrong* side of the pond.
Anyway, I recently got some DEC EtherWorks adapters:

They are not the best for multitasking environments (see here:
https://www.ardent-tool.com/NIC/Ethernet_Bench.html). But they should be
perfectly fine for the occasional file transfer or some light vintage
web browsing.
The adapters look good visually but are untested. I can test one before
shipping if you are willing to wait. Or we can YOLO it, up to you. You
can have it for the shipping costs (I'm from the Czech Republic, so
shipping to Finland should be relatively cheap).
Pertti, email me if you are interested.
