I want to have
as many different kinds of segments on my network
as I can manage, which means running a model 95 OS/2 system to bridge
between 10bt and tokenring on twinax.
To round out that heterogeny, you need a set of Thomas-Conrad ARCNet
cards (unless you can find 20Mbps-Datapoint cards), a passive hub,
and a serial-port-based Token-ring network that uses software written
in Russia. The Russian software lets you host drives that are actually
shares from other machines!
You'll want to use a Mac to bridge Ethernet to Localtalk, if you
can find the software...
What else?

DEC used to make an ethernet to SNA gateway based on
the uVAXII, didn't they?
At work we have a couple of the SNA gateway boxes, and they are
based on the MVIII, but the earlier versions were based on the
MVII. The boxes we have are DESNB (ChannelServer II).

OK. That makes sense. I never knew the DEC product names, just that
they sold stuff that did things like that.
We made PU2 intellegent serial cards that plopped into a Qbus or Unibus
backplane and spoke with PU4s over sync serial. We stopped short of
updating our products to PU2.1 and LU6.2 because the market was shrinking
faster than the product cycle could fund developement.
I still have a bunch of toys from those days, including a couple of HP
programmable serial analzers (the ones with the TU-58-style tape) that
we used to use to simulate the signon and bind of a PU5 for debugging
purposes; and an Informer terminal - a self-contained 3274/3270-like
device that you could daisy-chain, simulating a bunch of tubes hanging
off of a terminal controller.

That suggests
that what I am thinking of is a DESNA.
Most probably. The DESNA is a ChannelServer. The DEMSA and DEMSB
are the MicroServer and MicroServer-SP and are PU2, while the DESNA
and DESNB are PU5.
