It's not just the price which surprises me, but my overall impression
of the offer. They even have a clause saying that they might need to
spin a second board because this is a high-speed design, as if that
is their norm, but I don't get the impression that this would be
included in the offer. It's possible to get GHz right the first time,
and I get the impression that BMOCon are used to doing that.

Yep, that's right.

Yes, for "5(?)" boards, whatever that means. Is that about one order
of magnitude off?

Again implying that they will need more spins. :\

I agree that it's important to make bringup as easy as possible, and
I'm sure that BMOCon wouldn't mind adding such a clause if that's a
dealbreaker.

No I don't.

Yes that is clear.

Entities wanting to re-use and modify the Alpha board in their own
project.

By settling for a proprietary closed format of delivery, Cryptech
technology becomes significantly less usable for others.


> PCB source files are like closed format vector images,

There are open EDA file formats too. But the proprietary tools of
ourse do not support them, because proprietary tools lock in their
users. This lack of transparency is an important part of the
motivation for Cryptech in the first place.


> I doubt, that anyone will ever want to modify Alpha PCB sources

We can speculate about that all we want. The important point is that
when the deliverables are in a proprietary closed format, noone
without the proprietar tools *can* re-use the Alpha sources.

Who do you think is the Cryptech user? I think it's hardware developers.
