Oscar,
I forgot to ask for your private email on VCFB, so I use this public
channel.
Can you sell me a PiDP8, so I can port my Blinkenlight Api Server to the
platform of the upcoming 11/70?
I'd like to have it as preassembled as possible, 'cause my schedule is
very tight.

BTW, my photos of VCFB are here:

... you remember me shooting into your face while the street car rumbled
behind your back?
Thanks,
Joerg

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 :)
You hit upon one of the key needs for these projects, a good replica bezel.
In my project I had to have a plexiglass bezel laser cut then used white plastic
to frame that bezel. It works but I would love to have a replica bezel.
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.
Regards, Oscar.
