   Actually, the symptoms sound like two problems interacting -- a DOA
charger unit and bad battery contacts.

   Recall that lots of posters mention that the "Battery" DA isn't
dependable -- it fluctuates for no apparent reason.  I noticed that on
my Duo, and ignored it for a while...

   But only for a while.  After four hours' use, the "Battery" DA still
wasn't showing full charge, and -- much more seriously -- wasn't showing
the lightning bolt indicating the battery was taking a charge.

   So, I tried flexing the case (a millimeter or so) to explore whether
the battery contacts were working.  Sure enough, the "Battery" DA wildly
fluctuated.  Time to take the battery out and look.

   Looking at it, I was amazed that anyone could think such an arrangement
would work.  Check it out sometime, if you have a sense of humor.  However,
*anything* can be made to work...  I set out to clean the contacts.  (I used
a Pentel Clic Eraser (non-abrasive, and freshly rubbed against clean paper)
to remove any foreign material; then a Q-tip with clean rubbing alcohol.
(And for goodness sake, don't let your greasy fingers near any of this --
especially the alcohol.)

   After cleaning, everything started working.  The "Battery" DA started
giving stable readings, and the lightning bolt was on for an hour or two.
I rather expect it to give me trouble again in six months -- whereupon
I'll clean the contacts again...

Apple's line about this (whether it is true or not remains to be seen) is
that the emulation of the Mac on a PowerPC will not be detrimental because
the toolbox will be coded in native RISC code. Since so much of the mac is
the toolbox, and since so much of the code is spent accessing it, it will
balence out the slower emulation.

SoftPC on the other hand has to emulate the 8088 and all of the PC hardware,
since most MS-DOS programs access it directly. (MS Windows could probably be
speed up if someone could write a video driver that could call the Quickdraw
directly.)

Date: Mon, 23 Nov 1992 14:41:32 GMT

The "Se/30 32-bit clean" thread seems to have been going on 
at just the time that I have been investigating this problem
myself. I have an extensively modified Mac plus in which I 
am about to install a 68030 (not a commercial accelerator, a
board with PALs and real wires on it!). In theory this would
give me access to virtual memory via "compact virtual" if it
works. I had thought of modifying the memory map of the Plus
so that I can expant the RAM area and give me some breathing 
space. 
	To get above 16MB I would run into the "Dirty ROMs"
problem. I have been told by several people that "mode32" will
NOT work on an "accelerated" plus. The idea being that the
patches installed by "mode32" depend on the rom version and
are just incompatible with the Mac Plus ROMs. Fair enough.

	What I would like to know as a C programmer and Mac
hardware hacker is just what is "dirty" in the ROMs? Are the
"dirty" sections limited to the memory manager or speread all
over? 
	Connectix have a solution for the Se/30, the whole 
thing is only 27k bytes long, so what would it take to do it
for a Plus (or anything else that needs it)? 

	Any ideas/suggestions/comments..

 There's a small point that is sometimes overlooked when it comes to what
 a cache really does - how much it helps can directly depend on the program
 that is running. For example, in the rare case that there may be a 128k
 loop in a program you use often, a 128k cache will make a BIG difference
 for you - since a 64k cache could re-load itself twice a loop [depending on
 how it was designed]. 

 Here's my advice : try to find people who use the programs you use and find
 out if their caches help out a lot or don't. If whatever magazine gives
 statistics for various programs and you use one of them - utilize that
 magazine. Generalized comments about caches are usually pretty accurate but
 not always.

I'm trying to build a cable from a DB9 to a Mac 8-pin minicircular.
Here's the pin-outs:

DB9			8-pin minicircular

1 Carrier Detect	1 Handshake out
2 Recieve Data		2 Handshake in/external clock
3 Transmit Data		3 Transmit data -
4 Data Terminal Ready	4 Signal ground
5 Ground		5 Receive data -
6 Data Set Ready	6 Transmit data +
7 Ready To Send		7 No connection
8 Clear To Send		8 Receive data +
9 Clock/synch

I understand the DB9 side pretty much, but I don't understand
why the Mac has transmit + and -.  Which do I hook the transmit
on the DB9 to?  Or is this just not going to work?
On the DB9 I'm planning to wire 1 4 and 6 together so when it
sends out DTR it gets back DSR and Carrier Detect.  I figure
9 to 2 is probably a safe bet as well, but I'm not sure.

Any enlightenment would be appreciated!

More info on what I'm really trying to do:  A friend has an Atari ST
with a Mac emulator (a small box with a Mac 64K ROM in it).  He wants
to hook up a MIDI translator so he can run Macintosh MIDI software.
The Mac emulator does talk to the Atari serial port because he can
print from the Mac Finder.  So I figure there's a good chance the
MIDI thing might work, if I can build the right cable.

Thanks!

Does this only apply to external floppies, or can the power supply be (or not
be) plugged in while asleep?  I left my PB100 on my desk for a few days, and 
started it up (without plugging it in), and received a low power message,
that suggested that I put my computer to SLEEP, plug it in to the power cord,
and awaken it.  I have done so on a few occasions, and not seen any problems.
Should I desist???

Micron makes a cheap 8-bit board that sells for around $238.
You should be able to get a used NuBus Apple 8-Bit board for less
than $90. Check out the back of any MacWeek issue and you should be able
to find ads for several Used Mac Brokers or Mail order operations

The final and ONLY word about the stereo sound capability of the IIvx is as
follows:

1.  The IIvx has a stereo headphone jack.
2.  The IIvx plays mono macintosh sounds (beeps, soundtracker, etc.)
3.  The IIvx/CD ROM plays stereo CD sound since the sound comes from the CD
4.  The IIvx/CD ROM will mix mono macintosh sound with the stereo CD sound.


Apple has NOT covered up the fact that the IIvx has mono macintosh sounds,
just worded it strangely.  The Spec sheet clearly states this fact.  It
has also been stated in MacUser's table of Macintoshes.

The whole fuss about the sound was that many other older macs could play stereo
macintosh sounds, and the IIvx couldn't -- why?!

I hope this clears up ANY confusion about the IIvx's stereo sound.

The monitor measurements are all bogus.  Depending on how you measure your
monitor (from which part of the monitor to which part), you can get 13" or
14".  If your monitor has a power button the front, it's the new one.

Howdy:

Yesterday I proceeded with the upgrade, taking all the precautions with
static electricity, etc.  I installed a heat sink, but I went on and I
soldered the oscillator directly into the PCB.

The computer seemed to boot ok without anything connected.
However, when booting with my Color Pivot LE, all I got was a series of
black and white strips on the monitor (the system loaded, from the activity
of the hard drive). 
I took out my 12'' mono monitor, started everything up, and it worked perfectly.
Speedometer gave me 25% speed increase.
With my 12'' and the Pivot together, the computer recognized the presence of 
the Pivot, but I still had black & white stripes  on it. (Ok for 12'').

Now, the obvious solution would be to go back to 20 MHz. As I soldered the
oscillator, I had to desolder it, install a socket, and put the oscillator
in place. I damaged the original one (40MHz), but I'll get a new one on Monday.

Possible reasons:
- The Pivot card does want to run at 25 MHz.
- The card was dammaged during the process (Oh, no!)

Solution:
- Go back to 20 Mhz, and test the card.
- Tinker around with the card.

Any help would be appreciated. I'll post any conclusions when I get the
40 MHz oscillator.

When I upgraded the hard drive in my PowerBook, I removed the 2.5 inch 20 meg.

case gets plugged into the wall and runs off AC current. If I were to
