They also seem to bear the name of an aftermarket
supplier -
Systems Industries?- and some sort of system name, which I cannot
remember, but suggests typesetting.
May be the Atex (?) system, which I understand was very popular and
is still hanging on in some corners.
I've got some pictures around here somewhere from one datacenter of
a major metro New York area newspaper showing racks of what I believe
are rebadged pdp-11/x4's (they look recent, so maybe /84, /94, or one
of the goosed third party CPUs) dedicated to running Atex terminals
in newsrooms.
The systems are using some reasonably modern storage system - might
even be 3.5" form factor. But I wasn't in a position to inspect any-
thing too closely.
If I run across the snapshots I'll scan them and put them up
somewhere for grins.
