The *real* problem with Token Ring is that there is only 802.5 and no 
true specifications on the 'nitty-gritty'.  If you look at 'ethernet',
you will find 802.3 - but, you will also see very explicit standards
on it under the IEEE, i.e., 10BASE2, 10BASE5, 10BASET, etc.

There are NO specifications for the transmission media for TR...in addition,
the actual implementation is IMHO, antique.  In an era where even my humble
AM radio is fully solid-state, and my VCR is Digital, TR has mechanical
relays (and depends on Analog Phase-Lock to remove jitter)...even the
automotive industry is moving away from electro-mech relay technology.

Go to a large TR installation and listen to the clatter...then find a 1950's
Telephone Central Office and listen to the clatter...hmmm, is TR *really*
'50's technology?
