Tornado Avionics, Displays...
Dear Tornado-Techies,
in 2005 I asked on the "Spectators Balcony" of pprune regarding a black-box I got via
eBay and which should be from the early RAF-Tornadoes where it has been re-
placed by something newer. In the last years I reverse engineered this one
as a very interesting hobby project. This box called
PROGRAMMER ELECTRONIC CONTROL
contains a full 12bit computer with 8192 words of core memory and I was able
to bring it back to live again, i.e. I can write programs for it now and I even connected a
LCD to the box for a first "Hello World" program. A report on this restoration project can
be found in the vintage computing mailing list via this link:
http://www.classiccmp.org/pipermail/...ch/075079.html
An slightly modified version is available via pdf from the following link:
http://www.baigar.de/TornadoComputer..._ReportPEC.pdf
As I got quite far, the question arises, what the original purpose of this box in
the Tornado aircraft was . From some input I conclude, that it must have been responsible
for controlling some of the displays in the back cockpit. So I got some books from
Dour Richardson and Andy Evans to learn about the Tornado and the displays in
question are named the TV-tabs or the CRPMD.
Maybe on this forum there are people still knowing about technical details on these
vintage displays and whether the "Programmer Electronic Control" was involved
here, too?
Did the TV-tabs include some kind of analog storage included? From discussion
in the German forum "www.flugzeugforum.de" it is obvious, that German and UK
versions of the Tornado are different. Are the displays, too?
As every techie might imagine - the real dream would be to have one of
these original displays to connect it to the box. In Germany trashed equipment is
often sold on auctions (www.vebeg.de) to the public. Is there something similar in
the UK or is there an other way to locate one of these vintage displays?
Any hints are highly welcome,
best regards,
Erik.
P.S. the RAF-version of early Tornado contained a TV-tab like display for the
pilot, as well. Was this display technically similar to the TV-tab?

One of the stickers is from GEC Marconi - I know one major component of the early F2/3 made by them and it was little better than the concrete it replaced!
If your box is part of this equipment and you got it to work you did a lot better than the RAF who had to spend lots more money and effort to turn it into the good piece of kit it is today!

This doesn't really answer your question but to give you some more info - The F3 has 2 TV tabs in the back and 1 in the front. They were all monochrome (green) then a few years ago the rear ones were replaced with colour displays, but they can only be operated in monochrome (makes things a little tricky with 30 odd tracks on!) The front display is still the old tv tab (pilots dont break them anywhere near as often as clumsy navs
).
I think that the mono ones all went to the GR4 - but I could be wrong!

Hi and thanks for the answers so far. Maybe I have to apologize
especially to Olly O'Leg for using the term "vintage" in my question
as these displays seem still to be airborne and some people may be
annoyed by this term!
For me the term "vintage" is in no way negative. As the development
ot the Tornado started (I think 1968), the computers of thoses days
where PDP8 with 12bit and 4k of memory. The legendary PDP11
was released in 1970. Both where rather large 19" machines - so
it was a masaterpiece to put a machine like this into a box like the
Programmer Electronic Control. Additionally IO-Devices in those days
have been the keyboard and the teletype - graphics displays where
NOT commonly available. So these TV-tab displays where ahead of
time those days. This is the reason why many people spend their
free time in getting hands on and keep machines like this running.
So sorry again if anyone feels offended by my question. My only
interest is understanding how this interesting technology was
implemented...
Best regards,
Erik.

knobs below the display) than the normal TV-tabs.
So since the photo in the book shows even text on the pilot's display ths is definitively
some computer controlled display. Those days displays with internal analog storage
where widely used since the computer could draw the information and the display
will display it until a change has to be made - maybe the TV-tabs where of this type?
