50 Hz UNIX

[utzoo!decvax!duke!chico!harpo!mhtsa!eagle!ihnss!cbosg!ost]

   I am interested in UNIX systems running on 50 Hz DEC equipment
(in particular, 11/70's and VAX's).  I would like to hear from
anyone with experience on such a system or who knows of one.
Please reply directly a I am not a regular reader of net.unix-wizards.
I will also accept collect calls at (614) 860-4500.
