Is it possible that different kinds of devices were all badged "StarLAN"?

Ok, I pulled out my 'black binder'. It's a copy of the AT&T Unix PC
Reference Manual, and is for technicians doing component-level
troubleshooting of the AT&T Unix PC logic board. It's pretty thick
and contains sections on:
* System Features and Functions
* Logic Board Theory of Operation
* Diagnostics
* Logic Board Test Procedures
* Schematics
* PAL Equations
* Mnemonics
* Expansion Memory Locations
As I said, it's pretty thick... has this been preserved in digital
form somewhere?

I don't presently have one, but if I do ever run across one, I'd want
to make sure I had a "StarLAN" card (1Base5, for the pedants in the
crowd) - I even have a few official StarLAN transceivers and such -
they work fine on a 10BaseT network.
StarLAN does *NOT* operate on a 10BaseT network. ?The signalling is
similar, but the data rate is 1 Mbps rather than 10 Mbps.
