Subject: Re: Mac IIsi sound problems

Okay, this really should be a FAQ, and maybe it is, but I'll answer you anyway.

Many people report their sound going out on them with a IIsi. It has happened
to me, and it might be the same problem you are having.  The problem is most
commonly attested to a poor connection, and corrosion, between the internal
speaker, and the motherboard. Some have said this is a result of the way the
IIsi is constructed, that is without much solder.   Some have said the problem
can be fixed by cleanign the contacts between speaker and board, various
methods such as using a pencil erraser have been suggested. Others have said
this is only a temporary fix anyway as the residue will build up again anyway, and
someone even specifically cautioned *against* using a pencil eraser as it
could harm something or other.

In any event, spiking the power, that is turning the volume up all the way,
then back to it's previous level should cause the sound to come back. It will
leave again later, of course.  There is even an FKEY which will automatically
spike the volume and then turn it back again.

Also, it has been said that this is only an internal speaker problem, so if
you plug in external speakers there will never be a problem.  And even thought
the majority of people this happens to have IIsi (the majority of IIsi owners
have this happen to them? perhaps) I personally have noted a sound problem
which behaves in the exact same way on an LC.  So it could happen other
computers as well.

There. That is the IIsi sound problem, as I know it.  I think that was a
pretty good summary, and hopefully it was the last time it will ever have to
appear in this group, as I think everyone is getting pretty much sick of it. 
FAQ, anyone?

For those who want to actually buy the external version, you'll have o wait
awhile. Word on the street has it that the drives are in short supply, and
almost every one Apple gets is going into the IIvx and Performa 600CD.
Can't wait until the February Macs whom some say will have CDs as well will
affect the shipments! :-)

The DeskWriter will print grayscale. You need the latest driver (v3.1) to
get background printing and grayscale. They are available free by calling

I've found a place that sells Math co-processors pretty cheep and
I need to know if it matters if I buy a 68881 or a 68882.  I 
don't care about speed too much(I only have an LC). If a

68881 or a 68882
(oops)           ?  And they had different speeds, do I need a
particular speed for my LC (my guess would be the slowest...)
Well any words of wisdom would be appreciated.

There is only one internal SCSI port and only one hard drive power port inside.
 I'm not sure that you can put another drive in. I have a Mac II and I have loa

Powerbook:  160,180,210 & 230s all come with 4MB ram on the board.  They
do not ship with memory cards installed.   I just ordered memory from
Technology Works in Texas.  They ship (and I think most mail order companies)
the memory with the tools and instructions to install it yourself.  At least
with the 230 duo, apple allows the user to install the memory without
invalidating the warrenty.

Do you trust Disk First Aid 7.1?

I have had a Frog 100e external 105Mb Rodime drive on my SE for around 10
months and have been very pleased with it. I had a rather bad crash a few
days ago that corrupted it, so I went through the following time-honoured
ritual (because Disk First Aid couldn't repair it):

	1. Attach the drive to a IIci at work with lots of free space on
	   the internal drive.
	
	2. Boot from the internal drive.

	3. Copy all the stuff (except the System) from the Frog on to the
	   internal drive.

	4. Format the Frog using the Frog utility.

	5. Copy all the stuff back using the Finder.

	6. Rebuild the desktop on the Frog.

I then checked the Frog using Disk First Aid 7.1. It found "invalid sibling"
problems, so I repeated steps 4-6 again.

I then ran Disk First Aid about 10 times. Around half the time it found no
problems, the other times it found a variety of different problems (which I
didn't allow it to fix).

Norton Utilities cannot find anything wrong with the drive and it seems to
work just fine.

I called Frog technical support. They suspect a problem with Disk First Aid,
but promise to replace the drive if it goes wrong in any way during normal
use.

Does anybody out there have a *clue* what might be going on? Could it be
something funny to do with the driver?

This kind of weirdness is enough to put me off buying another Mac!

Thanks in advance, Andrew

MacLeak reported this a couple weeks ago. The Q800 and Q950 are both based
on 33MHz 68040's but apparently the 800 does get 'slightly better
performance.'

I would doubt that it is anything that you could notice without running a
hypersensitive benchmark test.

Indeed, It does!  I am, as I type, listening to some Wagner.  We took the Apple  
CD300 mechanism out of a (my)IIvx and put it in a drive enclosure (that came with an  
85 MB drive we put in another mac...)  The mechanism has an mini-stereo plug out in  
the front.  We send the audio signal to a couple of el-cheapo speakers deisigned for  
use with a walkman.  (You could send the signal to a bvoombox or stereo and have it  
amplified more to your liking (sp?))  I believe there is audio out in the back which  
you -may- be able to use.  If you are connecting to a NeXT, as we are,  you need to  
make sure the SCSI number is whatever it is supposed to be.

  About the SIMMS speed, the Mac+ needs 150 ns SIMMs min, so 100 ns & 70 ns

There are 2 kinds of boards: the resistor board and the jumper board.  If
it's a resistor board, you cut R35.  If it's a jumber board, you remove
the jumper (the one labeled 2/4M)

The AppleCD 300 has the ability to read RedBook audio directly over the
SCSI bus.  No analog conversion.  It's one of at least two drives that
currently have this ability, the other being the SGI drive mentioned
earlier.

This is not the same as the analog signal out the RCA jacks or headphone
jacks.

Does anyone know what the problem of error reading long supervisor word or
something is?  Every once in a while (fairly often), my IIsi drops into
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!

Joel.

I don't know how this was accomplished. When the 68000 first came out
it was not designed to support virtual memory. At the company I was
then working for, we did a lot of looking to see how we might get around
the limitations that prevented implementing VM. Finally we decided that
there were some instructions (notably the block move instructions I
think) for which not enough information was saved on page fault to enable
them to be restarted. Possibly Apple's compiler never generated these
instructions? On the systems I was working on, we couldn't guarantee
that users wouldn't program in assembly language and use these instructions.

I've been having trouble with an internally-terminated SCSI device (a Bernoulli

little erratic. Iomega's tech service folks suggested that I add a terminator  
block to the equation to see if that helps, i.e.

For what it's worth, the terminator that I have is of the II/fx flavor.
This goes against what I've read about SCSI termination, since that means that  
I have THREE terminators present. It also seems odd that the terminator isn't  
at the end of the chain -- it's in between the cable and the last device.
My major fears are that (1) this will damage something (2) this will only work  
erratically (3) this will not work at all (4) this will not work when I add  
more SCSI devices.
Can anyone shed any additional light on the subject?
