blinkenlights /blink'*n-li:tz/ n.
[common] Front-panel diagnostic lights on a computer, esp. a dinosaur. Now that dinosaurs are rare, this term usually refers to status lights on a modem, network hub, or the like.
This term derives from the last word of the famous
blackletter-Gothic sign in mangled pseudo-German that once graced
about half the computer rooms in the English-speaking world. One
version ran in its entirety as follows:
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.
This silliness dates back at least as far as 1959 at Stanford
University and had already gone international by the early 1960s,
when it was reported at London University's ATLAS computing site.
There are several variants of it in circulation, some of which
actually do end with the word `blinkenlights'.
In an amusing example of turnabout-is-fair-play, German hackers
have developed their own versions of the blinkenlights poster in
fractured English, one of which is reproduced here:
ATTENTION
This room is fullfilled mit special electronische equippment. Fingergrabbing and pressing the cnoeppkes from the computers is allowed for die experts only! So all the "lefthanders" stay away and do not disturben the brainstorming von here working intelligencies. Otherwise you will be out thrown and kicked anderswhere! Also: please keep still and only watchen astaunished the blinkenlights.

Old-time hackers sometimes get nostalgic for blinkenlights because
they were so much more fun to look at than a blank panel. Sadly,
very few computers still have them (the three LEDs on a PC keyboard
certainly don't count). The obvious reasons (cost of wiring, cost
of front-panel cutouts, almost nobody needs or wants to interpret
machine-register states on the fly anymore) are only part of the
story. Another part of it is that radio-frequency leakage from the
lamp wiring was beginning to be a problem as far back as transistor
machines. But the most fundamental fact is that there are very few
signals slow enough to blink an LED these days! With slow CPUs,
you could watch the bus register or instruction counter tick, but
at 33/66/150MHz it's all a blur.
Finally, a version updated for the Internet has been seen on
news.admin.net-abuse.email:
ACHTUNG! ALLES LOOKENSPEEPERS!
Das Internet is nicht fuer gefingerclicken und giffengrabben. Ist easy droppenpacket der routers und overloaden der backbone mit der spammen und der me-tooen. Ist nicht fuer gewerken bei das dumpkopfen. Das mausklicken sichtseeren keepen das bandwit-spewin hans in das pockets muss; relaxen und watchen das cursorblinken.
