Makes sense to me.

For the PDP-11, there are three kinds of plastic toggle/actuator: one like the
ones used on the mid-age PDP-8's, used on the 11/20; one sui generis one used
on the 11/05; one for the 11/40/45/70. The latter two use the toggle switch
(the one we've just been discussing); the 11/20 one uses a slide switch.
ISTR that there's a CAD drawing for the first kind, and maybe the third too.

No, makes sense (to me, at least).

PS: I can see where this is going: first we're already making parts like front
panels; we're about to start making/selling new cards (I'm thinking MEM-11,
etc, here); soon someone will start reproducing some of the older boards that
are now rare, and command high prices (my suggestion for the first - the M792
diode ROM board); and then it will be cabinets like the H960 (ditto); and then
finally, somewhere down the line, you'll be able to buy a complete,
brand-spanking-new PDP-8 or PDP-11. Just like the vintage steam engine scene
in the UK; first they started making new parts to repair the old ones, and now
there are several groups building entire new engines entirely out of new
parts.
This unfortunate creature has seen ill-storage and a slight mouse
infestation and bears the rusty scars of time and moisture. But with
your kindness and patience, it will have the chance to bound joyfully
through fields of Greenbar once again, bringing joy and the printed
word/ASCII art to all who meet it.
Called LA120 by those that bred it, DECwriter III by those who loved
it, you can call it yours for the mere effort of picking it up from
the Chicago suburbs. Shipping will probably be impractical and,
sadly, its time is short as my shelter needs the space for other lost
souls. The man and his truck from the glue factory are already
hovering along my road.

I have an M24 which does not have the bus converter card P1050). There are a
couple of these cards on ebay in the USA, which makes it expensive for me,
and I am not sure which of the two would be best anyway.
There is another bus converter available in the UK, but it is PC1076 (IF
622), which my web searches suggest make it for the M280 (which was a 286
machine).
Does anyone have any idea if this latter card might work in my M24? It
certainly looks to be physically compatible.

As my mail to cctech dod'nt came through, here a mail only to the cctalk
list.
sorry if it becomes a double post.
Hi All,
I was contacted via the greenkeys list for my spare parts of the two
T100 telexes, but I think it should be possible to obtain them in the
states. Is there someone willing to part of their broken or otherwise
non/half functional T100 in the usa.
they need the machines for a movie in the New York area.

A: Top-posting.
Q: What is the most annoying thing in e-mail?
I was checking out the Altair 8800 kit online (really cool). But I am
hoping to one day find a kit or plans to build a Mark-8 replica, since I'm
so deep into Radio Electronics features. I know there was a kit out there
(Obtronix?). Was it any good? Do I need someone to make a new kit or is
the Mark 8 within the realm of the home hobbyist the way the TVT was? Ie.
were there ever foil patterns available for those boards or did the kit
maker reverse engineer from originals? Is there any likelihood of finding
one of the replica kits still out there (I remember seeing one offered for
$2000 on Fleabay once.. )

Hi Guys
Well my missive on reproductions seems to have generated some interest.
There seems to be a lot of will to keep the old systems going and to
reproduce parts for them
and indeed build complete systems from new parts.
The main areas of interest are front panels (Not just DEC), key switches
and bezels.
Panels I can handle. Who wants to be the focus for switches and who for
bezels?
More than one person for each category can only be a good thing. I'll
call them "The Makers"
Those who want the items I'll call "The Takers" from 'I'll take one /
some if they get made."
Thats my two cents on parts sourcing.
The other topic was less computer centric and can be defined as "They
don't make them any more"
The UK is full of small companies making and repairing all kinds of past
products.
For example the MGB GT (a much loved British sports car). The factory
stopped making them in the early 1980's
However a few guys bought the press tools and have been turning out two
or three body shells a day ever since.
Copy of a Shelby Cobra - no problem build from a kit. GT40 clone oh yes!
Now we are not in that league but with the various tasks taken on by
those with the knowledge and experience
we can make the difficult to parts available.

That's a work of art, together with the PDP-10 he did. I saw them running on a nice touch screen at VCF Berlin, and I wondered whether all this physical replication stuff makes sense when that's around at zero cost. Then I put my blinkers back on and went ahead anyway :)

Did you perchance make a CAD design for that, which could be reused? ;) I'm drafting a design at the moment, but far from perfect still.
I think of all the technologies available for making the bezel, vacuum forming seems to make the most sense. Injection molding is much better quality but just too expensive (tens of thousands USD). The other approaches, I think, work fine for small quantities. But I suspect there's a 'need' to make a few hundred.
Probably the best way is to make a very good open-source CAD model. Then make a low-cost vacuum forming mold, whilst anyone could still use the CAD file for higher-quality one-offs on a CNC router or, perhaps, 3D printer. The problem with vacuum forming is that you cannot make much more details other than the outer hull, which will look fine but need a lot of work on the inside to really mount in an original PDP-11.

Right, I wasn't meaning to imply what you said was incorrect, just giving a
little more detail on what was a murky and complicated process.

Define "the Internet"! :-) If one describes it as 'the large collection of
interoperating networks speaking TCP/IP', then that statement _is_ correct!
If one instead uses a broader definition, something like 'computer networks
in general' (pulling in things like Usenet), then, no, it's not correct.
I'm _not_ trying to say that there is only one, correct, definition of 'the
Internet' - but various statements about 'the Internet' may or may not be
accurate, depending on which definition is used.
