Alright, here's the idea that I've got in my mind:
I have an old Performa which I was thinking about bringing Ethernet capabilities to, but couldn't justify doing it before. Now I think I can. The thing is to turn it into mostly just an ethernet to localtalk bride. Put an ethernet card in it's PDS slot, and then attach it to another Mac using localtalk, so that Mac could then see the rest of the ethernet network, and even the outside internet.
I'm sure this is possible, and is much cheaper than trying to track down an Asante adaptor (which seem to go for insanely high prices, compared to cheap PDS cards). The only thing is, does MacOS support doing this natively? If not, what software packages are required to accomplish this?
The Macs included in this are a Performa 6200CD (horrid design, but it works) and a PowerBook 180. Respective OS versions are 8.1 and 7.5.5 (Rev 2). Since this mostly deals with the capabilties of the Performa, it seems in place to have it within the PPC board.
