I only noticed the system resetting when I got my first 1Ghz system
prior to that, its possible the draw wasn't much. I mostly got it to
save the system from power drops, the infamous light dimming fizzle.
I was working on a system one night many years ago when the power
company decided to change out a transformer at 4am. I was always a
night owl, working second shift at the time, it was perfect for computer
exploration and programming. That night I heard lights sizzle, go on
and off about 6 times in 15 secs. By the second trip, I already had my
finger on the power off button, trying to save my drives. 40MB's
weren't as durable as today's drives. :)

The place I'm at is only 3 years old. Pretty decent on hookups, each
room is wired for cable and computer. However, I do notice the lights
flicker here a lot, at least once a day. Reminds me of the movie
"Christmas Vacation", when they kick on the auxiliary. :)

Yes, I am looking at picking up two when I can.
It definitely sounds like its on its last legs.
All I can say is I must have gotten lucky with this unit. I hate to see
it go, its been such a staple and durable device. I sobbed when my
floppy drive died (6 years old) hehe. I gave it a mock funeral, it saw
4 computer systems. It was a good drive. :,) hehehe.

hehe I saw one smoke at work one time. I don't know if it was a
defective unit. I think there was something in that caused it to short.
Thick white smoke.
Workers do stupid things when it comes to computer equipment. I hate to
see what some of these users houses look like. The colors... I cannot
get over some of the color schemes I saw. Enough to take that person out
to a pasture and keep them away from computers.
Computers have turned into peoples brains.
You know the 10% usage or was it capacity... :)
I need a Dual CPU that supports SMP for my new 3-D Poker/Solitaire Game,
the dealer moves too slow. If people only knew the true power of what
they have at their finger tips... ranting over... long day.. :)
