DEC disk pacs (and some magnetic tapes) everywhere.
…and some very good regular switches, too.

@mwichary My dad had an old electronic calculator — an enormous thing that must have weighed 20 kg — with a row of 10 or 12 Nixies for the display.

@mwichary Here's another circular mouse for you. This one came with the AT&T 5620 terminal (I used one in grad school back in the day).

Depraz Digimouse Mouse. The Digimouse mouse has 3 paper labels on the bottom that read The AT&T Digimouse box reads Instead of a steel ball like the older mouse's, a transluscent hard plastic ball moves freely in a larger opening in the Digimouse's retainer ring.
@mwichary because "design"?

@mwichary Why? Because they are great for some people. The ball inside is round and it feels right to grab round things. Why do most companies go out of their way to make mice look like this odd shape that is like nothing you touch in normal life?

worked some years with two 780s and a 750. These we're nice machines to work with.
But quite funny: my pimped Amiga 2000 at home with 68030 and 68882 FPU was running the same applications at comparable speed

My dad worked at ICL Gorton a couple of times.
