  I got my keyboard replaced (to RevB) to see if I could get the space bar
problem
fixed.  My keyboard also sagged at the lower left corner when a key was 
press. (ie the Control key).  Unfortunately the space bar is still very
insensitive but the sagging was fixed.  I think that is the only external

Hi-
I wrote a while ago asking if anyone had a problem with the Duo 210 keyboard  
where certain keys would sometimes give double-keystrokes instead of the  
normal one.  It's really annoying since I then have to go back with a spell  
checker to get rid of the unintentional double letters.

So I am wondering if anyone else has had this problem, or am I the only one?   
I suspect I have a revision B keyboard, and the keyboard was swapped out  
already, but that didn't fix the problem.  I'm going to get a logic board  
replacement and a new keyboard next week.

    Yes, they are talking about 832x624 monitors when they refer to 16",
but this isn't what the person was asking.

    What it depends on, really, is how much VRAM the LCIII will be able
to handle. From the specs it looks as though it will come with 512k
standard. Which is enough VRAM to support 8-bit color on 13" and 16"
monitors. The 4-bit to 8-bit trick of the LC/LCII is because they come
with 256k of VRAM, standard, that was just not enough to do 8-bit on
640x480 monitors, but was enough for the 12" which had fewer pixels. Due
to the number of pixels, the jump to 16-bit color on these 2 monitors
cannot be reached with less than 1MB of VRAM. Hopefully, the LCIII will
have this option, but I don't know.

Now that new Macs support VGA monitors I have an opposite need. I would
like to use the good old Apple 13" HiRes monitor, normally connected to
my SE/30, occasionally with a portable PC. Does anyone know if this is
possible? The sync signals seem to be different, VGA having separate H
and V signals and Apple using a composite sync signal. However, I
remember that I've seen some discussion on this topic before and also
some wiring instructions. If someone has such instructions I would be
more than happy to get a copy of them.

It's pretty amazing how fast things change.  Back when the Lisa
was introduced, everyone was running machines with 64-256K of
RAM.  One megabyte was a big deal then.  Now, 16MB is common
place.  Let's see, my Radius Rocket can support up to 128MB of
RAM and Fujitsu just introduced 256Mb RAM chips.  Sounds a lot
like the 1980s only our standards have increased roughly by an
order of magnitude.

   I discovered an easier way to get the duo trackball out, and I thought
I might pass it long.  The manual says to turn the retainer ring
counterclockwise and then lift the ball out.  For the life of me, I
couldn't get a good enough grip on the ring to turn it.

   My solution was to increase the coefficient of friction by using a
strip of rubber to grip the trackball retainer ring.  I found a fairly
wide rubber-band, and used it to grip the ring.  The thing turned fairly
easily with this crude device.  Hope this was helpful.

I bought a PLI TurboFloppy 1.4, used, for my Plus.  Hooked it into the SCSI
chain, and it worked right away.  Still going....

It was built with all the necessary firmware on board to handle mounting funny
Mac disks for computers that aren't savvy.  For Apple SuperDrive compatibility
 it's great.  It needs an INIT, however, to let it work with DOS Mounter
AccessPC/PC Exchange.  Without the INIT, you're stuck with Apple File Exchange
  No big deal.

I might mention that when I called PLI to inquire about AccessPC compatibility
 they were the absolute model of customer service and support--not unlike H-P.
 They directed me to their BBS.  A quick call, a quick 8K download, and I was
all set.

Note that PLI makes both the TurboFloppy and the SuperFloppy.  The TF can read
 write, and format IBM 720K and 1.44MB, and Mac 1.4MB.  The SuperFloppy does
all that plus adds Mac 800K compatibility--perhaps a plus in many replacement
situations.

   If that's true, $800 for a 16 Mhz '000 in a PB is probably wishful
thinking.  Especially since it would be a non-duo form factor, but without
an internal drive sort of deal--Apple factories would have to add a third

The DeskWriter family of printers are designed for the Macintosh.
The DeskJet family of printers are designed to work with PCs.

The DeskWriter comes in three flavors: DeskWriter, DeskWriterC and
DeskWriter550C.

The DeskJet also comes in three flavors: DeskJet 500, DeskJet 500C
and the DeskJet 550C.

Hope this clears up the confusion.

Does anyone know what the problem of error reading long supervisor word or

MacsBug and that's what it says the reason was.
When I try to restart the app/finder (ea) or quit it (es) from MacsBug, it
just drops right back in with the same thing!  I have to reboot to get it
to work again.

I tried reinstalling the system, but it still does it (though not quite as
often).  I can't say for sure what action causes it, but it's always when
I open or close an application or select something from a menu.  (happened
when I ejected a disk once, too!)

Do I have to reformat my hard drive? (groan...)  Or do I have a more serious
problem?  Is there maybe a way I can check my hard drive for errors?

Thanks all!

I have had a similar problem with two duo 230s I purchased.  In each case,
after about 8 hours of use, the lower button would click twice for each
time I pressed.  To be more precise, it made a 'click' sound twice,
but only registered one click, so it was more annoying than a real problem.
I took the first one back, but when it happened on the second one I
decided to take a look (not wanting to spend another 3 hours moving
files over appletalk).  It seems that the circuit board under the button
eventually flexes.  In my case that meant a second click sound, but I could
see that after a longer amount of time it would mean no click at all!

What I did was to wedge a thick peice of paper between the board and the
lower case of the unit, this prevents the board from flexing down when
you press on the button.  Has been workng for the last week no problem.

I also don't like the way the bottom corners of the keyboard bend when
you press a key - it has the same problem - there is no support under
those corners.  When you drop $2500 on a machine, you would think it
would not have this kind of manufacturing defect!

Hi,

My trusty old SE/30 is in need of a new logic board.  The nearest Apple
dealer is willing to replace it for $1,200 + labor, and I was wondering if
there is a cheaper way to bring it back to life.

I suppose I should just write it off and replace it, but I kind of like it and
would be willing to spend a few hundred bucks fixing it (keep it as a second
machine), but $1,200 is a lot of money.

Anyway, if you know of a cheaper source of a new logic board (can these things
be fixed by anyone but a Apple dealer?), I would appreciate if you let me
know.

Thanks in advance,

Go ahead and swap them. The SE/30 and SE drives do not use ANY -5v (just +5v
and +12v). You will still need the SE/30 analog board, of course.

The SE, after the installation, booted up fine with the finder;
however, some applications now no longer work.. ie Word 4.0. I feel
guilty since my roomate is currently working on his thesis and is

it.
