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.
(Hey computer, read the room.)
For blue, you have to go with IBM blue.
If you looked carefully, you might have spotted this Y2K readiness sticker on the last photo.
@mwichary I think @d_j_fitzgerald made reproductions of those for a recent show or conference!
