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 :)

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.
