Name that Ware, November 2020

The ware for November 2020 is shown below.

I’m not even sure if these boards are all from the same chassis, but they are definitely all from the same manufacturer. However, I suspect these will be stumpers, to the point where I’ve left the model number on the boards and I’ve only very lightly obscured a couple of logos/names. I have an inkling of who they are made by and what they are for; it’ll be interesting to find out if anybody knows more about the history behind these boards!
