I found---completely at random, in a bin of completely unrelated cruft--- the media interface half of an Asante MacCON/30ie (the ethernet card for the Mac IIsi or SE/30 at a recycler's yesterday. I picked it up for $10 because I thought I remembered somebody on the list was looking for specifically this half, but I can't remember who. It has both UTP and AUI interfaces, and all you need is the PDS half and the cable to connect the two. It's a standard IDC ribbon cable. I haven't counted the pins yet, but it looks as if it could be the same width as a ST506 data cable. If you're out there and you still want it (I should've haggled), contact me off list. ok r.
