DO NOT TOUCH

90% of internet in the 90s was hosted like this.

It feels like a loss that this is no longer the case.
- It absolutely is

PSU in the top, old round keyboard and mouse plugs... I get it, you shouldn't touch anything in a museum.

... did they stop putting PSUs at the top?
- Always at the bottom these days
It belongs in a museum!!

About 15 years ago I did some work with a large international pharmaceutical company with over 2,000 of offices across the world. There was a laptop in an empty cubicle with signs like this on it. Apparently if it turned off their entire email system would go down.

Props to them for repurposing old hardware instead of tossing it to a scrap yard.

Needs a blinkenlights sign

ACHTUNG! ALLES LOOKENSPEEPERS! Das computermachine ist nicht fuer gefingerpoken und mittengrabben. Ist easy schnappen der springenwerk, blowenfusen und poppencorken mit spitzensparken. Ist nicht fuer gewerken bei das dumpkopfen. Das rubbernecken sichtseeren keepen das cotten-pickenen hans in das pockets muss; relaxen und watchen das blinkenlichten.

Is that dutch?
- Gesundheit!
- no, i am pretty sure it is a mix of german words + made up german sounding words + english.
  I liked it XD
First time I read that was in about '89/'90 in a printed book of computer jokes gifted to me by my then mother-in-law. Still made me laugh. Thanks for the nostalgia hit.
Fire up your trusty LaserJet.

So, what they're saying is that the sign needs to be removed before unplugging anything. Gotcha, can do

There's always that one guy in the office too...

it started with a sign that only said "don't unplug the cables" and had to expand as things kept happening

PS2, VGA and RS232 cables. Takes me back..

My PC has those 😅

I had a photo kiosk at an old job that I wanted to put something like that for their USB cables. I swear you touch them during transfer and boom your download = canceled.

PS/2 port being used? How old is this image?

It could be from today. I've worked at several manufacturing facilities where something like this is hooked up to a huge ancient device with a serial cable because the drivers only exist for Windows XP and the Italian business who made the machine went out of business decades ago.
I suspect this was taken in the early 2000s, though, since the fan isn't caked in an inch of dust and grime yet.
- Yeah, this is a very clean PC picture, like new (though one can absolutely still get new mobo’s with legacy I/O ports) so probably not a modern build, just an older pic.

That must be a decorative exhaust vent then.

It bothers me that it's being blocked, but the motherboard also has a parallel port, so unless this thing is rocking a Pentium 4 (entirely possible), heat isn't going to be much of an issue.
