Yes, that's where the AUI port comes out. You need a Sparc-10 speakerbox
breakout cable which has a regular D-15 female for AUI ethernet on the end
of a short length of cable. I just happened to have one of these at home
which is in use with my Sparc classic right now.

I haven't seen 10baset (ie.twisted pair) to 10base2 (coax) adaptors, since
usually the adaption is from AUI to 10baseT or AUI to 10base2.

>3  Would it be easier to source another ethernet adaptor for the SBUS.

You could, but you'd still be left with another AUI or another twisted 
pair ethernet port (or both). Maybe there is an Sbus card with a coax 
ethernet port on it.. I've never come across one.

Regards,

Craig.
