Fan failure has been discussed at length here in the past.  As most people
know, the 3b1 fan will kick into "high gear" when the temperature rises inside
the case.  For the first couple years that I had a 3b1 the fan would
kick into high during most of the summer months - as soon as the room
temperature hit about 80.  I have since found a very simple "cure" for
this and would encourage others to take a couple minutes a week to do the
same.  Very simply, once a week I take a household vacuum cleaner and suck
the dust out of everything.  First I use a brush attachment to clean the 
the keyboard, monitor and case.  Then I use the "snout" attachement to 
clean the floppy slot, ALL vent holes and the fan exhaust port.  Ever since
I started this regimen (about 3 years ago) the fan almost NEVER kicks into
high speed, even with room temperatures hitting close to 90.  I got my
3b1 in (I think) 1987 and it runs 24 hours a day.  Still has the original fan
and everything else.  No hardware failures whatsoever.

>I would like to know *why* people think that this
>is a good idea.

Good idea or not "if it ain't broke don't fix it".  I live in a rural area
with really unreliable electricity.  Several years ago a storm caused the
power to cycle on and off multiple times during a short period when I
wasn't home.  When I got home my 67 mb disk was scrambled.  Re-formatting
fixed it, but I went right out and bought a UPS.  Considering how inexpensive
these are today I think its a pretty cheap "insurance policy."  And I've
been amazed at how long the 3b1 runs on my 325W Tripplite.  In one case when
I wasn't home it ran the 3b1 (2MB/67MB, EIA card, ext modem) for 3 HOURS!
When we discussed this several years back I think the conclusion was that the
3b1 only consumes 60 or 70 watts, despite the 250 watt rating on the name tag.

I constantly read stories of people's 3b1's "panic'ing", having disks die,
etc here.  Maybe I'm lucky?  All I know is that mine runs 24 hours a day
and nothing has broken yet, so I'm not going to change now.  Aside from that,
it wouldn't be very useful as a UUCP site if it weren't available 24 hours
a day would it?

Ok, I've recently acquired a dead 3b2.  The person I got it from said that it

Yes.  I simply replaced the (blackened) cap. and monitor came back to life with
no shrinking from right.  I couldn't locate a *mylar* cap. but used a metalized
polyester film cap. (which may be the same thing?).  I used a diode tester (on
my pocket Radio Shack multimeter) to test the transistor and diode also
mentioned in the FAQ.  They were fine.

I did have one unusual problem about a week later (Sept. 5, '92).  The
horizontal size became only about 3 - 4 inches instead fo the normal 8.2" (or
so).  Also, alternate raster rows were not necessarily aligning properly.
Looked like the horizontal deflection sawtooth waveform was being distorted,
i.e. low max. voltage and non-linear.  A cpl. of shutdown - reset (reboot)
sequences and cycling of power didn't help.  I poked around inside a bit
including unplugging and replugging a 4 pin connector (associated with
horizontal circuitry?).  A subsequent power off and on with the floppy diag.
inserted resulted in restored monitor operation.  Perhaps I fixed a connection
problem.  I did get one "unexpected interrupt from level 11" from the "All w's"
video test which I ignored.  I eventually executed the reboot command with no
floppy and haven't had any problems since.  I wonder if anyone has experienced
this?

Good luck!

I just looked inside a 720K only 3.5" drive: There are 2 heads inside - one
for each side of the diskette.  When I dosconnected each head - only one
disconnected at a time - only half of the tracks on the disk were readable
(either the odd or the even numbered tracks depending on which head I
disconnected.

This strongly implies that the 720K 3.5" drives ARE DSDD rather than SSQD.

Summary: Why shouldn't I shut down my computer when not in use?
Keywords: power-toggling disk-crash melt-down
Organization: UCLA, Computer Science Department
Date: Fri, 2 Oct 92 02:09:08 GMT

    Some people have mentioned that the 3B1 was designed to be left on
*all* the time, and that turning it off and on will seriously shorten
the life of the machine.  If someone could elaborate on this, I would
surely appreciate it, as I have not seen this discussed at length on
this newsgroup, nor is there any mention of this in the FAQ.

    When I originally bought my 3B1, I used to leave it on all the time,
until the Whittier earthquake (1987?), when I had a major disk crash.
(Earthquakes and disk accesses do *not* mix).  Fortunately, I was still
under a 90-day warranty, so AT&T promptly came out and gave me a brand
new disk drive for free.  (No backups at the time, but I had yet to do
anything *really* interesting with my machine, so no big loss).

    On another occasion, several years later, I left my computer alone
for about an hour, and came back to find it *constantly* rebooting.  A
quick feel of the top of the base revealed major heat build-up, so I
shut it off.  Once again, Fortune had smiled upon me, and I suffered no
disk damage, or even a warped plastic meltdown.  My computer has never
overheated since then, but I would not like for this to happen again
just as I am leaving for work ... so now I shut my computer off when I'm
done for the day.

    I would guess I turn my machine on about 2-3 times a week.  Does
anybody think this is an excessive amount of power toggling?  Given
my past experiences, I doubt that anyone could convince me to leave it
on all the time, but I would like to know *why* people think that this
is a good idea.

Whoa!  I just looked up the specs on the TEAC FD-35F, which was the original
"standard" 720K MS-DOS 3-1/2" floppy, and it definitely is double sided.

In any event, the real issue here would be the transfer rate, as we have
a MAXIMUM of 250kbs availiable from the stock Unix-PC.  This is compatable
with the 720k "standard".

"Quad" or "high" density disks usually have a higher rotational speed
and require a 500bps transfer rate, incompatable with the stock
Unix-PC floppy controller clock.

Specs on the FD-35F are: Double sided, 135tpi track density, Unformatted
capacity 1 meg.  MFM transfer rate 250bps.  160 tracks per disk, 80 cylinders.
Average acces time: 94ms! 300 rpm.
