Yes, I saved it then and thought to Edit it some more before I posted it
in the morning, but forgot to and just sent it on its way.

Some product specifications don't have both U.S. and Metric Units listed.
I appreciate it when both values are given.

The first Metric Value I learned was in the instruction sheet for how to use
Kodak Chemicals to develop 35MM Film.
Kodak always printed 68F/20C was the recommended temperature the Developer,
Stop Bath and Fixer chemicals should be at.

20C was a even number and it was easy for me to remember that was the same as
68F when I a young teenager, iirc 14 Years Old then.
Other literature that only shows a Metric Unit, I would have to consult a
Chart or Formula if I was wanting to know the value.

In the early 1960's I bought a Circular Slide Rule and a Weights And Measures
Conversion Table from a store in Hong Kong, then A British Crown Colony.
They were manufactured by Takeda Drawing Instruments Mfg. Company who iirc
is in Japan.
Takeda called those two products by the "Concise" brand name.

Their Weights And Measures Conversion Table had Equivalents of Imperial,
Metric and Japanese weights and measures.

I have forgotten that the U.S. Units are called Imperial and have thought
the Japanese Units were the ones called Imperial, My Mistake, Sorry.

I never saw the movie called The Ugly American, but it looks like I'm one of
them.

I still wonder if the Tripp-Lite UPS charges the battery when I have it turned
OFF, but without a Schematic I wouldn't know for sure.
A long time ago I bought a 12 Volt15 Amp Power Supply and wrote Tripp-Lite
asking if I could get a Schematic for it to put with my other Amatuer Radio
papers and they sent one to me.
I'll send an Email to them to see if I can get one for my UPS so I can find
out if what I think is correct, or not, about the battery being charged while
it is plugged in a A. C. wall socket.

The monitor I have is LCD so it gets power from the UPS so I can see what's
happening.
I tried using Tripp-Lite Power Alert USB software but it had problems with
this XP box so I stopped using it.
If the UPS starts Beeping I come running if I'm out of the room.

 HG> That isn't really necessary, since the machine starts up in an ordely

OS/2 figured out a Better Way than MS has, I'd say.

 EV> Yep, the Nuvistors do that job.

 HG> Please don't use words/names that you don't know the meaning of.

 HG> The nuvistors are/were low-power triodes, used in UHF amplifiers

All I can say is DUH!, as I wrote above I intended to Edit that message before
sending it on the next morning but I forgot to look to see if I used the
correct "ISTORS" word.

MOV - Metal Oxide Varistor is the ISTOR I should had typed.
What can I say but DUH!

 HG> MRI XMAS,

I did have a good one, hope Yours was good also.
