hello everyone,
I am looking for the data sheet of the dlart dc319.I did not find it ,I
found only a few informations in micronote 33,and schematics using it in
several cpus.If someone has the file or any pointer,I'll appreciate ?the
purpose is to look
what it really does and how,and the differences
with standard dl11 devices.
thanks very much ,best regards

If there isn't already a scan on the 'net, I think I picked up an
original paper copy last weekend when I was loading my station wagon
full of PDP-11s. I'll check the documentation stack this weekend.

I met up with another member of the list who wanted to find a home for

an 11/03, a rack-mounted "naked" 11/03 (backplane and PSU bolted to a
19" aluminum plate), a "MicroPDP-11" (11/53 w/RD51 and RX50) running
MicroRSX v3.0, plus a few terminals (VT100, VT320 and DECwriter IV)
and docs+floppies to go with. My Saturn station wagon was filled to
the scuppers (barely a slot at the top to see out the back window).
I used to have a PDT-11/150 but sold it years ago to another
listmember from Kentucky (not sure he's still a subscriber or not), so
I was happy to get another one. I've never had a MicroPDP-11 (just
MicroVAXen in BA-23s and older Qbus PDP-11s in BA-11s), so that one is
going to be fun to play with. I've excavated an ST225 and an ST251-1,
saved from Intel PCs, that have been on my shelf awaiting attachment
to an RQDX3 - 20MB should be enough for RT-11, and 40MB should be
enough for 2.11BSD.
So that's the score.

Recreating broken plastic toggles has been queried on the list many times, ran

this is the part about creating the toggles, maybe someone can translate
the info better than google translate
It manufactures key with the Fimo dough, armed with a small piece of
nickel to increase their rigidity, after casting a survivor. .
The axis is replaced by a small rod metal.On can mix different colors of
Fimo dough to get the desired shade.
The mold is made of Siligum Gedeo, pulp molding bi.

That looks very nice. I know people who cast plastic at home, but his
results look amazingly clean.

That's because he's not casting, but rather using a polymer clay:

Are you familiar with this material and what his process might have
been? Was the mold of the same material, do you think?

I don't know what he made the mold of, but anything, including
plaster of Paris should work. I've never worked with Fimo, but I've
done a few things with Sculpey; it's kind of porous, which makes me
wonder how good it would be for a toggle switch handle.
It might be better to try this with one of the two-part epoxy
sculpting material, say Apoxie:

hello ,here are some explanations
I made the mold with a two components silicone product used by dentists
,several makes exits according to local ressources.I just used a
surviving handle .It is the silicone mix that is poured over the handle when
liquid,all that in a small plastic box to contain everything of course.
After is is solid (like rubber of course) the silicon is cut in two with a
cutter ,the original handle is
carefully removed.The Fimo paste is
rather smooth ,not solid ,not rigid when new and not cooked .I fill the hole
in the mold with light but firm pressure ,take care of filling everything
,not leaving holes .The result is not porous ,to make it even better , when
still hot I cleaned the fabricated handle with a soft sand paper.The result
is bright handle ,no hole ,no porous surface.
No not forget the metal piece inside the fimo,and the small rod as axis
,Fimo is not strong enought to sustain mecanical efforts.Cooking of Fimo
paste is done in a microwave owen:the fabricated handle in the mold is put
in a small glass with a few quantity of water,10 minutes cooking....ask xyl
for the user's manual of your microwave owen:-)))
I hope it is precise enought ,excuse for some unprecise or inappropriate
words,the vocabulary about making DEC pdp8 handles is not in my
dictionnary:-))

Alain,
Thank you very much for the explanation of your very clever
replacements!
Do you think that adding some glass fibers (as is done with polyester
and epoxy composite materials) would improve the mechanical strength
of your replacement?
For small metal rods, I maintain a stock of stainless steel bicycle
wheel spokes in various sizes here. They can often be gotten used
from the local bicycle repair shop for next to nothing.
I can't
begin to tell you how many things here have been repaired with one of
these... :)
Best regards,
Chuck

You can also try Shapelock. This only requires hot water(boiling hot)
to soften the plastic pellets which you can mold into any shape. I use
it to build custom mechanical parts for my robots or pinball games,
there's lots of uses for this. Once it's cooled, it's just as hard and
rigid enough to also let you use a dremel or a CNC machine to further
customize your parts.
If you build a mold of the switch, say using a block of aluminum on a
milling machine. You can then use a press to fabricate the switch
handles with just a ball of molten shapelock plastic.
