(of course with an external power supply) DataComm Warehouse sells a 4-port 10Base2 repeater for $199. I've used one of these before and it works just fine. If you really need to extend or segment a thinnet, this is probably the least expensive way to do it. > I am asking because quite often I have seen RJ45 "transceivers" to be > connected to the AUI port which are a block of plastic with > only wires inside.

I suspect this won't work, but it'll only cost you two transcievers to find out. The AUI to BNC transcievers I've worked with get power from the AUI port, amongst other problems, so you can't just wire two of them back-to-back. -- "Where am I, and what am I doing in this handbasket?"
