Folks, I _think_ SimWare was out of Ontario, and joined Wiremold. www.wiremold.com
BUT the SAM was produced in @1990, while the earliest Internet Archive
snapshot is a single one in Dec 1996.
The relays in the Token-Ring MAU (multistation access unit) connect
active stations into the ring. Every station needs to have its own
unique connection into the ring, but this doesn't mean that you have to
buy an eight-port MAU just to add one more node. The fact of the matter
is you don’t have to buy a MAU at all.
A company called SimWare ((800) 451-3683) markets a product called SAM,
for Single-station Access Module, which links PCs over Token-Ring
without a MAU. A SAM device looks like a regular Token-Ring cable that swallowed a mouse. The lump in the cable ts actually the same type of
relay contained in the typical MAU.
You can use SAM cables with regular MAUs in order to add a node by
connecting to the OUT port in the MAU. You can even use two SAMs to link
two PCs directly for troubleshooting, backups, and any other chores. The capability to combine MAUs and SAMs lets you design a network for
economy and efficiency, and according to SimWare the cost of using eight
SAMs is less than the cost of a single eight-port MAU.
