Some fun photos from Large Scale Systems Museum near Pittsburgh!
This magnificent Enter on both sides of this Singer/Friden minicomputer console.

DEC disk pacs (and some magnetic tapes) everywhere.

Some very good on/off switches…

…and some very good regular switches, too.

(I liked the whole hierarchy of toggles in that last photo.)

Although the FILE UNSAFE… switch? light maybe? was unexpected.
A strange way to put an LED inside a button.
On the other hand, this is a cool way to choose a font.
This Dasher line famously inspired Severance set design…
…but I have never seen a screen-less printer-terminal like this one!
Speaking of, some more nice keyboards.
Loved this guarded (and hyphenated) RESTART key.
Which one is more scary: a Mac keyboard pretending to be a Space Cadet, or a Kaypro keyboard with an extremely intense overlay?
(Mastodon rate limited me! More in a bit.)
I miss the old terminal proofreading-inspired icons for INSERT and DELETE.
Here: symbols for inverse video, blinking, underlining, and… something?
This is a rare space-saving variant of the famous DEC keyboard that established the inverse T arrow key standard.
All the classic colors of CRTs: amber, white, green, and burn-in.

@mwichary That one twigged some nostalgia: My father worked for Control Data, and some of my earliest clear memories are of him taking me to work, and seeing an animated Snoopy in flying ace gear flying his doghouse across the screen — in ASCII art no less, at first.

Long time ago. <sigh>

(As a bonus, the amber brought to mind my old Hyperion mostly-PC-compatible “portable”, which I still have)
