I agree it would be really neat. The odds of pulling it off are slim,
unfortunately. Consider the Typeset-11 system. There were under 100 sold
world-wide, I think. Each was a custom turnkey system, set up to talk to a
particular model phototypesetter with the specific fonts that the customer
ordered. The terminals are application-specific too. I'm not sure if a
VT-61/t can be used as a VT52, it wouldn't surprise me if the answer were "no".
And a VT-71 won't do anything unless it's first loaded with operating firmware
from the host, which came packaged with Typeset-11 (or a later VMS typesetting
product whose name escapes me).
That said, if anyone were to come across bits & pieces of Typeset-11 (TMS-11)
I'd be quite interested in dusting off old brain cells to help bring it back to
life.
Phototypesetters of that era were often quite big machines. At DEC we had an
Autologic APS-4, which is a gray box about 6 feet on the sides. A fair number
of customers had its successor the APS-5, which is somewhat smaller but not a
whole lot. The smallest machines I remember were the Mergenthaler Linotron
202, about the size of a large high speed copier. Later models of that one
supported PostScript, I think, but the Typeset-11 I worked on predates all
that. Half a generation earlier and also fairly small would be optical disk
based machines, where the letter shapes are kept as shapes on a spinning glass
disks, with a flash bulb to expose the chosen letter onto the film via a set of
lenses that produces one of a number of font sizes. And I still remember the
very early model CRT based phototypesetter at the San Diego Tribune, from III
if memory serves -- it was basically a small room that you'd walk into in order
to unload the film.
And yes, those machines produce output on photographic "film" (paper rolls,
actually) which has to be developed and fixed, then cut, coated on the back
with sticky wax, and pasted onto layout boards.
The whole production process, from film to layout to press, is quite complex
and comes in a bunch of variations. I understand it slightly, but all that was
the province of skilled union tradesmen whose trade has long ago vanished into
history.
And never mind an actual printing press. Newspaper presses of course are still
around, and probably not changed a whole lot. They are big, loud, and scary.
Watching them switch from a used-up roll of paper to a new full roll, on the
fly without stopping, is quite a spectacle. Especially because it *usually*
works -- but if it doesn't it's rather a mess.
