My powerbook 170 woke up this morning with a black line on the screen.
If I put it to sleep, or switch it off, remove battery..., the two
ends of the line remain black...
Has someone ever experienced that ? Should I ask for a replacement screen ?
The screen had one void when I bought it, not in this location.

A  specific question:

Is it true that one can use this combo at different resolutions? This

Something crawled into my Powerbook and died.  Just behind the

addition to a couple other specs of dirt.

I know this sounds like the old stories that IBM salesmen used to tell
about Ampex memories, but frankly this interferes with my enjoyment of
my Powerbook.  And, like so many Powerbook owners, I got mine in order
to compensate for a wealth of personal inadequacies so that any
problem goes straight to my heart.

Questions:

1) How did the bugs get in?  (I admit to taking the machine to the
Sierras for a month, but it was in my car most of the time)

2) How complex/expensive is it to get them out?  Can I do this myself?

It's about a year since I added a 14" color monitor to my SE/30.
During that time I've never found a "real" use for the 9" B&W
screen.  Sometimes I remember to drag tool palettes or Word's
spell check window over there but usually it displays a blank
desktop.

I wondered whether other netters have come up with creative ways
to use those 29 square inches of valuable real estate.  One
thing I'd like to be able to do is to have my disk icons appear
over there but of course thay always mount on the "menu" screen.
Is there some hack to change this?

Any good uses for a B&W monitor or should I try to let it as
advertising space?

Supposedly an LCII with 40Mhz PowerCache will operate at close to the
speed of a IIfx.  All the PowerCache's have 32K of 25ns RAM cache built
in, and they claim an 80-90% cache hit rate, which mostly eliminates the
bottleneck of the LC/LCII's 16-bit data path.

After a while though, the only thing that could spin up the drive was
removing it, shaking vigorously and then replacing it and booting up.

I also have a SE/030 but I added the hard drive myself.  Lucky for me
because I bought the hard drive with a VISA Gold, which extended the 
warranty to 3 years.

I called Quantum (don't have the numbers on me right now) and they have a
swap program that exchanges the drives for ~1/2 of the street price.
I paid $175+tax+shipping for a new 105M, which comes with a new two year
warranty.  However, VISA is paying for it, so I'm happy. :P

Before I swapped it, however, I had Quantum send me a new EPROM which 
tries harder to spin up the drive.  This works but only if you set the
system to wait about 10s before looking for the drive.  It seems to take
longer to spin up with this PROM.  I used this only has a temp measure 
so I could back up my data before going the swap route above.

The October issue of MacUser magazine indicates that there is NO
Apple Computers Inc upgrade path for the PB140. In other words,
no you can't (officially) upgrade a PB140 into a PB145.

On the other hand, any PB140 that is sent in for repair is returned as a
PB145. Might that not be an *UNOFFICIAL* upgrade method?

Sounds rather expensive in any case.

Date: 25 Aug 1992 17:37:51 GMT

Distribution: na
NNTP-Posting-Host: avalanche.berkeley.edu

We bought a Mac LC a few months ago (*right* before the LCII
was announced) and bought a GoldStar 14" VGA monitor to go along
with it. The back of the monitor calls it a model GT3031, but the
shipping list says model 1450 from MacDirect. The Mac and
monitor have been on continuously, with a few shutdowns, since
February.

We are starting to see problems with the monitor. There are slides
on the front to control brightness and contrast. When the contrast
is set more than halfway towards the high end the screen inverts color.
The color inversion is not exact: some blues turn to yellow and some
don't; likewise the black/white inversion is not exact: a vertical
black line develops a white ghost to the left, a horizontal black line
has no ghost, while the white background turns black, obscuring both
original lines.

I don't know enough about these monitors to know what the problem is.
It seems that one of the electron beams (I assume it has three for the
color) is not aligned with the others when the contrast is changed.
I recall that the Apple 13" has a button on the back to degauss. Of 
course, I don't know exactly what degaussing does in a monitor.

It's still under warranty but before I send it out I'd like to
try to find out what the problem is. Anyone have any ideas?

SAVE YOUR POWERBOOK FROM DAMAGE NOW!

Enter the Mac Powerbook Screen Protector.

This device sits comfortably over the top of your Mac Powerbook screen.
The screen adheres to the Powerbook by means of non-marring removable
adhesive strips.  The protecting screen is clear and shields the Powerbook
screen from scratches, fingerprints, smears and bugs.  

Yes, bugs...

If you have ever used your Powerbook at night with the backlight on, 
you know that bugs are attracted to light.  We've actually seen a unit
that had an insect that had crawled into the seams of the backlight, and
the replacement cost was enormous.

Did you know, that to replace the screen on the Powerbook 100
would cost $790, on the Powerbook 140 it is $880, and for the Powerbook
you will pay a whopping $1600! All these costs are WITHOUT LABOR!.

Every precaution should be taken to protect your Powerbook screen. 
Since I started using this screen protector, I have felt so much more
comfortable using my Powerbook, that I use it more that my home Mac IIci.

This protective device has a cost of only $29.95.  Call now for your
order.

I have two hard drives from a TI Explorer--I think they're 200 MB
each.  The Explorer itself is no longer in use.  I'm not a hardware
person, and don't know anything about the specs on these drives.
Heck, they might even be SCSI -- does anyone know what the TI Explorer
used?

If any hardware person out there has any knowledge of TI Explorers,
you're the person I'm appealing to for help!  (If you don't know
anything about Explorers, educated guesses are also welcome.)

What would it take to convert these drives for use on a Macintosh?  Is
this worth looking into, or would it be ridiculously expensive?  If
it's worth looking into, who would do such work?  What do I need to
find out about the drives?

(BTW, I don't actually own these drives, so I can't sell them.  I can
either use them or trash them.  So no offers, please.)

E-mail preferred, as I rather strongly suspect no one else on the net
is interested in the answers.  Thanks much!

Subject: Bernoulli MacTransportable Pro w/IIfx
Date: 29 Aug 92 12:52:14 GMT
Organization: The Great Beyond


Awhile ago I posted that Iomega had just released a Mac-specific version of
their hard drive (the MacTransportable Pro 90) with a 40% reduction in price.
In fact, the street price on this drive is about $499.

I also posted concern whether this drive would work with the IIfx, since the
IIfx has "weird SCSI" and since the Bernoulli drive is internally terminated.

A MacWeek article had said that IIfx users could "just add the special IIfx
terminator."  I was not aware that the IIfx terminator could be placed
_anywhere_ on the SCSI chain (this really doesn't make sense to me..  :)),
so I didn't see how the terminator could be added.  (BTW, I have a
LightningScan Pro SCSI hand scanner hooked up to my IIfx -- without the IIfx
terminator..  Never had any problems.  Is this good or bad?)

So, I decided to call Iomega, just to make sure the MacWeek article was
correct.

The tech support person I talked to told me that no, the new Bernoulli drive
was _NOT_ compatible with the IIfx, at least not yet.  That I would have to
get the regular Bernoulli drive (several hundred dollars more) so I would
have two SCSI ports.  This was bad news, because I really wanted the drive.

I posted a plea for information on the net, and several people replied that
the IIfx terminator didn't have to be at the end of the chain, and that
there really shouldn't be a problem.  Thanks for the info!

I called Iomega yesterday, and initially talked to a non-tech person, and
explained the situation.  She told me she was very surprised that someone
at Iomega would say it wouldn't work with the IIfx.  She doubted that, but
she transferred me to the technical department just to be sure.

The lady I talked to there was very friendly and said Iomega would never
release a drive that didn't work with the IIfx -- that that would be a crazy
thing for them to do.  She said the worst that would happen is that I'd
have to get a 25-to-50 pin SCSI cable.  But, just to make sure that the
drive did work with the IIfx, she ran down the hall and talked to one of
the drives' engineers.  He confirmed that it did.  (It wasn't clear if I
needed a cable or not.)  But she told me if there was any problem at all
with the IIfx, they would gladly refund my money.

Soo..  I called MacConnection and ordered the drive for $499.  I should be
getting it any hour now.

I'll post my findings..  Hopefully it will work without a problem (and won't
fry the rest of my SCSI devices, or anything like that.)

If you've got a Mac, and need a Mac-specific hard drive, this drive (so far)
sounds like a great value.  For $499 you can't go wrong -- Bernoulli has
an _excellent_ reputation, and you can just get new 90-meg cartridges
whenever you need them.  (Apparently the price on them was dropped 40% too,
so they're very affordable as well.)

Later!

The SIMM speed will not affect performance, as the powercache (as its
name implies) includes a 32K cache of static RAM (SRAM).  I think the
SRAM is 16 ns -- not even close to the 80 ns SIMMS you are considering
buying.

You should probably check this out with Daystar, just in case I'm
grossly misinformed.

Yes, "Quadra 256K VRAM" is what you need.  512K VRAM will *NOT* work.
A little-known fact is that the Quadra 256K VRAM is the same as the
256K VRAM that comes standard with the LC.  Many people upgrade their
LC's with 512K VRAM, so you may be able to find someone with unused
