VAX/VMS V4.6 on a cluster of two VAX 8530 and one VAX 8250, and upgraded
to V5.0
VAX 11/730 with VAX/VMS V4.4
MicroVMS 4.7 on something
Customer systems included:
VAX 11/750
MicroVAX II
Some PDP machines, running TSX-Plus and some other multiuser OS
Lots of MicroVAX 3100 series, running VMS V5.2 through V5.5-2Hx
Some smaller, early AlphaServer
AlphaServer 1000A/233 with OpenVMS V6.1
AlphaServer 1000A/266
AlphaServer 1200
AlphaServer DS10
AlphaServer DS20
AlphaServer ES40
These AlphaServers up through OpenVMS 7.3
VAX 4000-200
Two customer servers replaced with vtVAX, running OpenVMS V6.2 and
OpenVMS V7.1

Never Itanium.

I'm only aware of one customer still running VMS and it's on a vtVAX.
