To recap:
Several people, including me, have posted here about problems with their Duo
battery losing its charge after only a few days.  One person reported that
they actually had to have repairs to the logic board.  I thought I'd relay my
solution to my problem.

After getting quite annoyed at having about a 1 minute charge left on my 
battery, and no luck with the recharger, (and irritated that I'd have to
take my machine in for service), I took the battery out to look at it.  When
I put it back in, it started charging like a madman and has held its charge
since.  (And yes, I am sure that it was _all_ the way in before.)
Silly me, I thought that for >$2000, these machines would have better
battery contacts than your average transistor radio.

The Moral of the Story:  Check your Contacts.  (And thanks to those who
emailed me and suggested this, even after the fact.)

The 10MB limit *is* imposed by the ROMs.  On the original LC you wouldn't
be able to exceed the limit (2 MB motherboard RAM + 2 * 4 MB SIMMS = 10 MB).
However, on the LCII you should be able to get to 12 MB, since it has 4 MB
soldered to the motherboard - but try it and you'll find the machine can
only access 10 MB.

I too am anxiously awaiting the upgrade offer.  However, somehow I just
don't believe the $500 price quoted in MacWeek.  In the past it seems that
the cost of upgrading was something like 60-70% of the purchase price of
the new Mac.  Please, Apple, prove me wrong!

Eric is correct.

The existance of an on chip MMU has nothing to do (in this case) with the
ability to implement Virtual Memory (VM).  The 68020 doesn't have an MMU
*on chip* but many systems have been built (Mac and others) that have
a VM implementation.  The MMU just needs to be there, either in discrete
parts or in the form of the 68851.  The problem with VM and the 68000 is
that the bus fault frame didn't allow for restarting of most instructions
after a bus fault or page fault.
One of the major differences between the 68000 and the 68010 was that
the 68010 had a new bus fault frame that allowed for restarting
instructions.  A 68000 system can be designed (and was) that can provide
the appearance of VM by doing full process swapping (instead of paging),
and thus allowing for several programs combined to consume more memory than
was physically present.  But in my book, this isn't the same as virtual
memory, in that a single process/program can't reference more memory
than is physically present.

I don't know how the Lisa was designed, nor if/how it implemented VM.
And yes, data in code segments is usually a problem, most especially so
with processors like the 68040 that have separate paths and caches for
instructions and data.

Thanks to all who responded to my original posting.  It turned out
that the cause of my "printer not responding" error was a loose
power cord connection on the printer, and had nothing to do with
either the serial cable itself, nor whether it was plugged into
the modem or the printer port on the Mac.

I never suspected the power cord connection was bad since the
"power" and "ready" indicators on the printer were on, and the
printer passed its self-test.  But because the cord has a 4-prong
plug, what apprently happened was that the prongs supplying power
for the printing mechanism were solid, but the ones powering the
communications interface to the Mac were not.  Re-seating the
plug fixed it.

the only use of mmu is virtual memory, so it is true that 68000 machine can't
use virtual memory. that does not mean there is any affect on the performance.
286 can't use virtual memory either. i could be wrong.
what i posted is some marketing thinking, it is interesting tot see how those
computer and chip companies competing with each other.
as far as i know, the top line of mac used to be faster than pcs, however, p5
might change the picture(486 already is better than 68040 at the top speed).
that means apple will HAVE to switch to powerpc to kepp the performance
competitive. however, recent news about overheat of p5 bring some uncertainty.

Sure.  Set the processor speed  to standard, and set it NOT to rest,
restart, and run Speedometer.  If you are running at 16Mhz you will
get an overall rating of 4.  If you are running at 25, you should get
at least a 6, depending on RAM speed and the HD.

The Quadra 950 does _not_ require that larger capacity DRAM SIMMs be 
placed in the lower (or upper, for that matter) SIMM bank.  You can place 
either 4MB or 1MB SIMMs in any bank, in any order.   At startup memory is 
sized independently for each bank, and then all banks are stitched 
together in hardware into a single contiguous physical address space.

Whatever your problem was, it was not solved by placing the larger SIMMs 
in the lower bank, per se.  Perhaps one of the SIMMs was not seated 
properly in the socket in your original installation?

Something not in your table that you might want to consider is length of
warrantee. I think the quantums are 2 years. Not sure of the others.
I tried to replace my stock 40 meg conner in a IIsi with the Maxtor 213,
and, because the Maxtor is just a bit longer than the conner (front to
back),
it interfered with the logica cache card that I had installed. Just
something
to watch for. I ended up getting the els170 as an external drive, and am 
satisfied with it. I also use the quantum 240 at work, and that's a nice
drive also. I've dealt with both APS and MacDirect. Macdirect's brackets
never have the holes in the right place. On drives we bought from them, we
could only get 2 of the 4 mounting screws to go in, because of the
misalignment.
In those cases, the drives were Fujitsu. I guess it's possible the holes
on
the drive were in the wrong place, and the brackets were ok.

I'm looking for a good driver to use on my SyQuest drive.

I just got a an 88c (from Mass Micro) and I also use cartridges in an 88
and
some in a 44 also. I use some 44 and some 88 M cartridges.

I've tried three drivers so far.

Mass Micros (3.0) doesn't recognize that when I put a 44M cartridge in an
88
(non-C) that it can't be written to. It doesn't display a 'lock' icon in
the
disk windows, instead just gives a disk error when I try to write a file.

MicroNet (5.4.4) puts up the 'insert disk' dialog when the cartridge is
already installed and sometimes the disks show up as 'ejected' when they
are initially mounted. anyway, when either of these happen I have to
spin down the cartridge and spin it back up to use it.

I used to use Disk Manager Mac (2.1? or something like that) and SyQuests
formatted with it don't show up in Disk First Aid unless they are the
boot disk. They say '--no disk found--' instead.


Somebody please help me. I'll pay a reasonable amount of money for a
driver
which handles all my problems well.

Please e-mail replies.

The PowerBook 145 has 2 MB soldered to the motherboard.  The supplemental
memory modules come in 2, 4, and 6 MB size.  Usually, a 145 will come
with a 2 MB memory module in it.  To increase memory, you pull out the
2 and replace it with a 4 or 6 (isn't that wasteful?).  So it's a good deal
that the 145 came with 6 MB.

A PowerBook 140 has a 16 MHz 68030; a 145 has a 25 MHz 68030.  Neither has
an FPU.  In a Speedometer test, a 140 should run more slowly than a stock
IIsi (which has a 20 MHz 68030 and no FPU), and a 145 faster.

Connectix PowerBook Utilities ($49 mail-order) will tell you how fast
the processor is running.  For example, a PowerBook 160 can run at 25 MHz
or 16 MHz (plus the equivalent of 1 MHz in processor idling mode).  The
160 comes with a control panel that let's you switch processor speeds 
between 16 and 25 MHz.  It seems like you should be able to do the same
on a 145 (but not on a 140) -- maybe a 145 owner can find out.

Hello.  We just got in some 8 Meg SIMMs and were trying to install them
	in a IIci.  We took out the existing 4-1 Meg SIMMs and put in 
	the 8 Meggers.  We then booted and turned on the 32 bit 
	addressing in the memory control panel.   Oh, they are installed 
	in the first bank.  We currently get bus errors or Finder, bad
	f-line errors when we boot back up.  And the last time we booted
	(no extensions--as were all the previous boots), we got a dialog
	box with a bomb in it, that just flickered, no message, just the
	flickering box with a bomb in it.  

	If anyone has done this, how did you accomplish adding the 8 Meg
	SIMMs?  Thanks for any ideas.
