  If you take all the static precautions it is a piece of cake.  After
removing
the necessay screws (do not remove the one under the trackball) the
keyboard
lifts off and the memory slot/connector is easily accessible. The modem
looks like a different story.  I think you need to take apart something
else
to access it wasily.
  I added memory to my Duo last week.  I bought it from Newer Technology
because
their 4 MB base module can be added onto later.

Eric, some people have indicated in other posts that the keyboard was
a bit flimsy in its construction. Specifically, mention was made of
the fact that if you press down on the "cntrl" key the left hand side
of the keyboard has 1mm or so "give". Have you noticed this on your
210?

I just got a PB170.  I wonder if the battery is ok on it!  How long does
a fully charged battery last under different power conservation settings?

BTW, in system 7.1 the Portable CDEV (control panel) has been replaced by
Powerbook CDEV.  In the Portable control panel you can specify the time before
the system or disk goes to sleep; nut, in the Powerbook control panel you can
only select a position from the 'Maximum Performance' position to the
'Maximum Conservation position'.  I think the original method was better because
it was clearer as to what the computer is doing.

Thanks a lot.

   Martin,

   It seems as if the *big* problem might be: "How to keep your daughter's
   healthy interest in such things alive...without damaging anything important!".

There should be a degaussing switch on the monitor.  You can also
pickup degaussing coils in some electronics supply places that
deal with TV parts.  There is nothing "permanently" wrong with the
monitor (or shouldn't be anyway).

Hello there everyone.  Hope ya'll had a good holiday season.  I know I

question 1:  Can I hook up the SE and my Quadra as to take advantage of
my speed and better networking capabilities?

question 2:  If I use my Quadra, could I use the cables already there
(appletalk and network) and connect the SE as an external monitor.  (Mine's

I am thinking a video cable would do it but I'm not sure.  Any suggestions?

Subject:  Performa memory
Organization: FAA / Mike Monroney Aeronautical Center
Date: Fri, 8 Jan 1993 18:30:35 GMT

I recently bought a Performa 600CD, which came with 5 meg of memory --
4 soldered in and 1 meg added so I am told.  I want to add a 4 meg
simm which would give me a total of 9 megs.  Will this work?  In a
MacUser magazine article on memory it says that the performa 600 can
be configured for 4, 5, 8, 12, 20, etc.  If I have five and add four,
doesn't that give me nine?  The question is, must all of the simms be
the same size (with the possible exception of the original four?), or
can a 4 meg simm coexist with the 1 meg already installed?

Also, MacUser claims that I can install memory in my Performa without
voiding the warranty (well, they didn't mention me personally ... :-)?
I mean, is somebody out there ABSOLUTELY sure that I won't void the
warranty?  I can't find any written word from Apple stating the fact,
though to be honest I haven't looked at all the docs I got.  I may be
missing some docs because I took delivery of a demo machine.  Now, I
don't need warnings pertaining to the physical act (ooooohhhh!)  since
I went to school to be a hardware tech on (gasp) IBM equipment back
when an AT was something to brag about (though I gave that up when I
got my CS degree -- I'm much happier now as a programmer, thank you).
I know simms are different (presumably easier than chips), but I am
well aware of static discharge and other hazards of tinkering with the
innards.

Thanks.

I guess it'll work as a color TV, shut the monitor off for a few
minutes and back on. Or if the monitor has a de-gauss button, press it
and wait until the image stops waving. The procedure may have to be
repeated a few times.

Both the pb 160 and pb 145 are 32-bit machines, where that means that they have
a 32-bit wide data bus. I suspect that their performace is very close; a recent
MacUser (december?) had a chart of all current mac's performance. Unfortunately
I left it at home over Christmas and don't have access to it now!

What they probably meant by 'greater performance' was either: a trivial but
measurable difference in speed for some reason; or simply that there were
more options to make you perform better, like a greyscale screen, video out,
etc. I suspect the latter.

Well, the Mac LC is a steal at its current special offer price in the UK

I have upgraded it to 10/105/512k and I've just bought an Ethernet card 
from Focus (which is presumably on its way here).  The Ethernet card has 
a socket for an FPU, and Focus recommend MC68882.  Question is, will an 
MC68881 work?  The 68882 part is out of stock at all the places I've 
tried where I can get it cheap.

Also, will there be some sort of Apple upgrade program from the LC to the

I have a Personal Laserwriter LS with the 512K memory they come with.
I'm somewhat confused from some conflicting info I got when the newest
driver came out (7.2). I heard that it allows full size printing on
legal sized paper (if you choose "Use larger print area") without expanding
the memory. It was also _implied_ that since the new driver it doesn't even
help to add memory anymore.

Well, my experience with the new driver is that on a reasonably complex legal
sheet (I do a monthly newsletter), the smallest margins I can get without 
graphics just disapearing is about .4" all around, even using the larger print
area. I'm printing from Works 3.0, which has plenty of problems, but the problem
is even worse from Word 4.0. What I'm wondering is, will more memory even help,
or is the new driver written so that it doesn't have to know how much
memory is in the printer? Or is it the program instead of the driver, since
things are clipped in Print Preview? I'd really like to use that extra space,
and the memory only costs about $25.

First: Are you able to use double-sided (800KB) disks with
       this computer?
       If you can format disks two-sided try the following...

       Obtain the 'NewLife 1' CPU upgrade from NewLife
       1-800-663-6395 Ontario, Canada. 

       This will give you Mac Plus equivalent if not a bit faster.
       There is also space for up to 8 SIMMS to a total of 4MB.
       The SCSI connector allows use of HARD DRIVE.

Second:Get 8 256KB SIMMS. Since they should be FREE (no use to 
       anyone anymore) get a dozen. You will have extras in case
       one is bad and you can swap/test combinations until they all
       work. (Static charges might kill a SIMM)

For $300 (especially US$300) you should be able to have a 2.5MB
Mac Plus equivalent. There are 16 and 25 MHz upgrades for the 512
but they are more money.

Remember that the above advice is dependent on your Mac being able
to format double-sided (770-800KB) disks. If you can only use
400KB (single-sided) disks then you have a 512K Mac which must be
upgraded with the 128K ROM and 800K drive kit. You might want to buy
a used Mac Classic or something else for less than a $1000.

If you do upgrade with the NewLife you should try to get a used
hard drive. It makes an improvement on speed of use and convenience.
I have seen System 7.0.1 (maybe System 7.1 too), System 6.0.8,
Word 5.1, Excel 3+4, and most other recent software still be able to
work on a 512Ke (double-sided disks) with the NewLife. You may want
to use System 6.0.x for slightly faster responses.

Note: There are no guarantees that you upgraded 512K is going to last 
very long. I have seen the 512Ke with NewLife still going after two years
though...
