Well, at least you HAVE a console.  When I first encountered this problem I
had ONLY an X terminal (DEC VT1000) and thus NO way to CDA VIEW PostScript
files.

The problem is that the PS interpretation is done by "PostScript extensions"
in the X _server_, not in the CDA-Viewer _client_ -- and DEC did NOT put the
necessary PS interpretation capability into the server code built into the
VT1x00 series of X terminals.  As far as I know, there is therefore no way to
CDA-View a PostScript file on a DEC X terminal, and it also seems unlikely
that "generic" X terminals would have the necessary DEC extensions either.
(But I know very little about this subject and could be wrong on the subject
of "generic" X terminal behavior.)

I suggest finding an alternate X-based PostScript interpreter/viewer in
which the client side does the conversion-to-X-image; I do not know any
such software specifically.
