several companies make adapters to MAU to increase the number of
 nodes attached to the MAU; as a fallout of this, some of these
 adapters can be used without a MAU to connect two nodes.  RAD is
 the only company I can think of now; I don't have their number
 but you can try the directory assistance for 800 numbers.  Make
 sure you ask for the model which can be used without the MAU.

Hope this helps.

Re: TokenRing format specs; the Technical Reference for Token-Ring
Network PC Adapter provides programming information for the token
ring interface (originally TOKREUI, currently LAN SUPPORT PROGRAM)
as well as direct interface to the TokenRing adapter hardware.
This also contains just a tad of information regarding the adapter
hardware itself as well as the Adapter Cable pin details.

If you are looking for Token-Ring frame specs (specifically
MAC and LLC frame layouts and protocol details) you will need
the IBM Token-Ring Architecture Reference Manual.

The former manual is usually available at PC dealers (selling
IBM T/R adapter) and IBM Direct; the latter is available only
from IBM Direct.
