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.
Fun tape changing instructions on the device itself.
Not-so-fun instructions from an accounting computer that was used at a funeral home.
Fun arrangement of ports on an IBM computer + a secret inventory # Gorton.
Just a lot of shoddy Gorton all around. 🧡
The future was once now.
A lot of wires in the old computers.
Why do companies tried to make circular mice happen so hard? I think this is the third one I know of (after the iMac puck one and the later NeXT one).
In my next life, I want to come back as a Nixie tube.

That’s it! I spent most of the time on the first floor with big machines. There is an entire second floor with a lot of microcomputers, but those were more familiar to me.

It’s currently by appointment. The volunteers were very nice!
