>Q. Does the QMS PS410 have an Adobe PostScript interpreter?

PS410 User's Guide says `PostScript licensed by Adobe Systems,
Incorporated' and the initial copyright notice sent back in the
interactive mode says
  PostScript(r) Version 52.4
  Copyright (c) 1984, '85, ... '90 Adobe Systems Incorporated.
  Typefaces Copyright (c) 1918 Linotype AG ...
So it *seems* that they do.
