Yes.  Supported display include:
     o hpa1096 Mono-VRX     1280x1024x1
     o hpa1416 Color-VRX    1280x1024x8+2
     o hp98705 Personal-VRX 1280x1024x16+4  (entry 3D)
     o hp98735 Turbo-VRX    1280x1024x24+4  (high-end 3D)

A statement was made by someone close to HP marketing that multiple heads are
not officially supported on the Series 400 workstations.   Despite this, we
(HP's X server development/test team) have some 400 workstatsions with multiple
heads.   To the best of my knowledge, there are no problems, but I think HP
marketing is trying to determine how popular this configuration is before
requesting additional testing and then officially supporting it.

One 400 workstation only has one slot, therefore one display max.  The other
has ?3? slots.  In that case, each display is independently addressible when
installed.

*** If multiple heads are important to you, speak up.  This is one of those
    "it should work, but why support it if few people want it" situations.

The server has always been able to support 4 screens.  This applies to the
s300 and s800 workstations, and should unofficially on the s400 workstations.
