Take a good look at the connectors. Replace the plastic key. You
wouldn't think it important, but it helps guide the plugin so you
don't blow it up when you plug it in hot...


You are NOT supposed to "hot" plug TM500/5K units.

You are NOT supposed to spill coffee on your laptop.
You're NOT supposed to cut yourself shaving.
You're NOT supposed to drive your car into another.
You're NOT supposed...well...you get the point...$#!^ happens...
and having the key in place reduces the carnage when it does.

Actually,it does not.
It all depends on which contacts are made first.

You are absolutely correct...it depends. And you should ALWAYS turn off
the power before removing/inserting plugins.
The key wasn't designed as an alignment aid, and it doesn't provide much
help, and I didn't intend to overblow it's importance.

Color me conservative...


BTW,I worked for TEK for 21.5 years,testing,calibrating,and repairing TEK
test and measurement and video test equipment.I've worked on plenty of
TM500 items.

I defer to your experience. I was merely the engineering manager for
much of the TM500 stuff that came out in the mid 70's.
