WangNet uses a dual-cable topology and has divided the cable's bandwidth among
a number of services: Wang Systems (also called Wang Band) dedicated
interconnect services (now Multivendor Services) Utility Band (Utility Service)
and the Peripheral Attachment Service. Each WangNet service uses its own set
of transmission techniques, each with its own form of access control, its own
data transmission rates, and its own place on the network's frequency spectrum.
Each also uses its own interfacing hardware.
Though Multivendor Services is an 802.3 service, accessible to Macintoshes with
Ethernet cards via their MAUs, as of December, 1989, there was no gateway
between the Wang Systems and Multivendor Services. Similarly, there was no
WangNet/AppleTalk gateway.
You might consider alternatives like serial connections for file transfers or
terminal emulation. These techniques that are well-documented in the Tech Info
Library and in the Apple Multivendor Network Solutions Guide.
One mail gateway is SNADS Gateway/MSMail from SoftSwitch, Inc. This product
lets Microsoft Mail 2.0 users exchange files with users of Wang Office, DISOSS,
PROFS, ALL-IN-1, and Hewlett-Packard Desk.
