How does it handle greyscale images?  Does it cut them to 5 bits or
does it use a different compressor?

This looks exactly like a situation I had with a network of 25 macs
with several printers. Trouble was finally diagnosed by polling all
nodes on the net from one end of the backbone. The responses to the
poll can be read out on an oscilloscope. What you look for is marginal
signal amplitude coming back. The "normal" vs troublesome signal
strengths will be visually very clear. Find a bad wire or connection
and repair. The trouble is that Appletalk is a very forgiving protocol
and will tolerate lots of noise without any noticable effects. But
printer packets get lost and ...

I also had some success with a 230kHz signal source and a 'scope
to find and fix problems. Usually the net showed about 0.1v drop
from node to node, each node getting "fainter" as the signal source
was moved further from the 'scope. The bad link showed a much higher
drop. 

If you are having net problems, this is a pretty good basic check
since it validates the _physical_ network layer (or is that _electrical_,
oh well I'm splitting hairs...). E-mail me if you have questions,
this newsgroup ages off my host pretty quickly and I'm liable to miss
a posted reply. Good Luck!!!!!

Any Mac with a Superdrive in it will not accept high density disks formatted
in double density.  I have no idea why this is the case and it is a real
pain sometimes.  Anyways, to fix the problem just put a piece of tape or
better yet write protect stickers from old 5 1/4" disks over the extra hole
in the high density disk.  This will let the LC read the disk.

Organization: The Ohio State University Department of Computer and Information Science
Date: Thu, 9 Apr 1992 16:36:36 GMT

We have two large Macintosh labs (~200 Macs between the two of them)
which currently are equipped with Mac Plusses and ImageWriters (1 per 10
Macs).  We want to start upgrading them, and want to start with the
printers (hey, it's not *my* idea!).  I'd like to hear from other people
handling Mac labs, as to what printers they use in the labs.  Both Apple
and third party printers will be considered.  

We're looking for printers that will be more reliable than the
ImageWriters, and faster as well.  In fact, we'd like to reduce the Mac
to printer ratio, while *still* improving printing speed for users of
the lab overall.  A secondary concern is finding quieter printers.
Print quality isn't an issue; in fact, too high a quality printer would
almost be bad, since we want to avoid becoming a place for studnets
outside of our department to come and get free printouts.

Also, notes on how to prevent the above situation are welcome.  Ideally,
we'd want the "legitimate" users not to be inconvenienced by whatever
mechanism is used to control printer use.

Thanks for answers in advance; if there are requests, I will try to
summarize to the net.

Subject: Memory Speed, will it make a difference?
Organization: DSG, Stanford University, CA 94305, USA
Date: Thu, 16 Apr 92 01:09:07 GMT

I'm looking into upgrading the memory on my Mac IIci with a cache card.
I was just wondering if anyone can tell me if the simm access time will
really make a difference.

The choices are between 80 ns simms and 70 ns simms, and I believe you can
get 9 bit simms that run at 60 ns and 53 ns.  I read here once that
you can simply plug in a 9 bit simm and it will work fine in a mac.
It just wont use the ninth bit.  Can anyone confirm this?

The clock rate of the IIci is 25 MHz, which gives it a clock period of
40 ns.  When the CPU makes a request, I assume that it takes 2,
maybe even 3 more clock ticks before the data is retreived and on the
third or fourth clock tick the CPU can resume.  If it is three clock ticks
to retrieve data, then using 70ns chips may reduce it to 2 clock ticks,
then again maybe it won't.  60 ns and 53 ns simms could conceiveably
reduce it to one clock tick.  Does anyone know?

Also, how does memory speed affect the cache card.  What is the speed
of the SRAM on the cache card and how much is it?  Would 53 ns main
memory render the cache card useless, or even harmful?

I will post a summary of replies.

Followup-To: comp.sys.mac.hardware
Organization: The University of Texas at Austin, Austin TX

I work in one of the residence hall computer labs here on the UT Austin campus,
and we have not upgraded to System 7 because of one big problem:
Our current security system on the Macs relies on having all the applications
in invisible folders, and launching them using On-Cue or by opeing a document
of one of the applications that is "hidden".
Under System 7, invisible files, or files in invisible folders, are truly
invisible- not only on the desktop. Under System 7, openig a document of
one of the invisible applications (applications in an invisible folder or
applications that are themselves invisible) is UNSUCESSFUL. That is, the
Finder cannot find the application to open the document.
Also, the Finder cmd-F command (Find) is not able to locate these invisible
files. 

We do not want users of the labs to be able to copy applications from the hard
disks of the machines, or delete those applications. Basically, we need our
applications protected from copying/deleting. Since System 7 renders our
current sceme inopperative, we need a new method.

If anyone knows of a method that would work for our purposes, please send me
email. If you think others would be intersted, then post your info here, too!

Thanks.

Subject: 105/120 Mb HD w/ LC
Keywords: Quantum, Maxtor, LC
Date: 15 Apr 92 15:48:38 GMT
Organization: University of NC at Charlotte

Hi y'all,

I seek the accumulated wisdom of the net to answer a HD upgrade question...

First, background information:  I have a Mac LC 10/40 w/ FPU running 7.01+.
I want to get a new hard drive, something around 105 to 120Mb.  What I am
leaning toward is buying an external high capacity hard drive, remove the
high capacity hard drive from its box & stick it in the LC, and put the 40Mb
drive in the external box for occasional transport.  I am reasonably sure
that I can stick the high capacity HD in the LC as long as it is a Low Power/
Low Profile mechanism; from what I've seen in the ads Quantuum makes a 105 and
Maxtor has a 120 Mb drive that satisfy the LP/LP criteria.

Question 1)  In order to make the big HD my primary internal drive, do I need
to move a jumper or switch to change its SCSI address?  I think my existing
40Mb address is zero, so I guess I will need to switch it too.  (Note the
40Mb external drive won't be used that often, and I will be booting from the
105/120 Mb drive.)

Question 2)  Price and form factor of the external HD are major considerations.
The smaller the external case the better for transport.  I am thinking about
getting a 1x4x8" Pocket Portable from Relax Technology.  They offer the 105
Quantuum or the 120 Maxtor for the same price: $379 as of 4/6/92 MacWeek.
From the illustration it looks like the drive comes with an external power
supply, but the "wall wart" looks reasonably small.  Has anyone dealt with
Relax?  (Their ads say they are a 14yr old company.)  I'm leaning towards
the higher capacity Maxtor mechanism over the Quantuum since the price is
the same.  (I'm aware of Quantuums 2 yr warranty, but also aware that most
places are backordered by severall months).  Comments on Maxtor reliablity
compared to Quantuum would be welcome.

Thanx much...

	If every square micron of backplane space was so important, why
didn't they just put on a standard BNC ThinNet connector.  It's not

Once more I hacked the Apple HD Set-up program, which was only
letting me partition 40meg of my 80meg as a "Mac" drive...
There are resources in it called lcol(?) which are the partion
"rules" for the different selections, and for some reason the
wild-card (FFFF FFFF) for Maximum Macintosh wasn't working correctly.
This particular field in the resource, I determined to be the size
of the partition to set up (in .5 K increments), which using resedit
I set to the exact size of the partition I wanted.
Ugly, but it got my hard-drive back to full capacity.  One caveat is
that although this field is in .5 K increments, make sure the partition
set up is multiples of your block size... 2K in my case.  Setting it up
otherwise appears to corrupt the partition map which can't handle
fractional blocks (?).

I also had a request to upload the original hack to the sumex archives,
which I will do tonight.  It is in the form of a teachtext document
which tells you which bits to twiddle in the Apple HD Set-up code
resources.

Use Northon SpeedDisk.

Check the media, Northon utility will mark the bad blocs by creating files for
each bloc and put them in a folder. This will prevent your system of writing
in these bad blocs.
