Testing the HP-35's chips at Mostek

[EdS2]

I just read this great article by Fred Beckhusen, who worked in the top secret(*) testing facility at Mostek, where they were one of two manufacturers of chips for the HP-35 and successors:

They also tested the bulk of the world's supply of Z80s, apparently:

and points nearby.

(*) Not really. But there was a code name, and HP's name was used only on a need-to-know basis.

Thank you so much for this!

It's a really interesting article and totally on topic for our main forum so I moved it there for better exposure.
