Jeff,
I had (and still have to some extent) the same problem on my Executive. I
managed
to mitigate the problem somewhat by replacing the 12 volt muffin fan with a
117 volt
fan in order to reduce the load on the power supply. The shimmering was
reduced, but
not eliminated.

those are magnetic strips storing programs. you would read the strip in,
then insert it in a special holder below the row of function keys on the
calculator. you could label the strip so you remember what each function
key is programmed for. HP first introduced this with the HP67 (pocket
version) and HP97 (desk version) and TI followed suit with their own
equivalent. This was probably vintage late 70's or early 80's?

I remember going into the local Radio Shack and drooling over the
different TRS-80 models nearly constantly in the period between 1982 and
1987, seeing as those were the systems which I had easiest access too. I
wanted a Model 4P quite badly at the time, but I didn't make enough with my
job for them to even think about financing me on it. I entered the military
in 1983 so didn't make too much. Also, the Model III was the first micro of
any type I got to use, since it was what our computer lab in high school
(circa 1981-2) used.

If I remember correctly, didn't IBM originally charge close to $5000
for it's hard disk system for the original PC-XT's?

The Indus-GT floppy for my Atari 800 was another 5-1/4" drive that
was in the $300-400 price range. Nifty drive though, and I think I have
close to a dozen different DOS's to boot it from.

Howdy all,
In our newspaper they have a little item called NO KIDDING. In it
they list little trivia things. A few days ago there was one on
"Now You Know" listing things that are different than history says
(one was that Linbergh was actually the 67th person to fly solo across
the Atlantic). Each daily listing also shows the reference in case
no one believes.
Anyhind in today's list they had "'Why' behind the names"
The reason for certain names of companies/items.
Apple - desire to be before "Atari" in the phone book.
Atari - to look like a Japanese company
Does anyone know if these reasons are true? Sounds funny but then
we really don't know how/why certain names are chosen.

I have an origional Apple IIC owners guide, under the "Ask Apple"
Section, there is a question that says: "How did Apple get it's name?"
The answer: (Taken from the Apple IIC book, Apple Presents the Apple IIC,
An Interactive Owner's Guide.)
"The name Apple Computer was chosen late one afternoon as Steve Jobs and
Steve Wozniak, Apple's founders faced the deadline for filing a
Fictitious Name Statement, part of the business licensing procedures.
After volleying names back and forth with Wozniak for hours, Jobs looked
at the apple he was eating and decided that, unless he or Woz arrived at
something better by five o'clock, they would call the company Apple. Five
o'clock came and went; Apple was the new company's name."
This could be true, or not.

I like that one. Good explanation for the bite.

Pulled out the Japanese dictionary and the definition is close.
"a hit" or "on target".
For awhile I guess they were.

I didn't take a really close look but it didn't appear to be painted. It also

I have an Osbourne Executive that is in fairly decent shape and for the
most part works fine. There's no burn-in on the CRT and both floppies work
great, but there seems to be a problem with the power supply or the video
system.
The system boots fine, but once it has booted, the image on the screen
begins to jump or shimmer, and you can hear the fan on the rear of the machine
appear to change speeds, as if there was a power fluctuation.
I would really like to find out what's wrong with this machine, and repair
it if possible, and am hesitant to run it the way it is. Any help would be
greatly appreciated. Thanks.
