Trouble is, there's no cable-only solution that will hook a modern machine
to a 10Base2 or 10Base5 network at all.  They require that the machines
have either 10Base2 or AUI interfaces (and for AUI, transceivers are also
needed, which hardly qualifies as "cable-only").  Nobody builds those into
machines any more, and interface cards which have them are scarce and
costly (and, again, don't really qualify as "cable-only"). 

The signalling conventions of 10Base5/10Base2 are not compatible with
those of 10BaseT; you can't plug a 10BaseT-only machine into 10Base5
or 10Base2 without electronics in between.
