Subject: Administrivia 

I put some information on other Internet archive sites in the file
/info-mac/misc/other-archives.txt. I'm sure this file is very incomplete.
Please let us know about sites we are missing.

It would be very nice if someone with access to Usenet would volunteer to
send us the contents of comp.binaries.mac. That way we could keep our archive
better-stocked, and perhaps reduce some of the "I missed that posting, could
you resend?" traffic on the comp.sys.mac newsgroup. Send mail to
info-mac-request@sumex-aim.stanford.edu if you would be willing to help us in
this.

I put some new GIF 256-color picture files in the /art/gif subdirectory.
There are also some new files in the /unix subdirectory. One set is for
use with /comm/zterm; it supports the Zmodem protocol. Another is the file
bhcomb-c.txt; it knits together multipart postings and strips out all of the
garbage. Bhcomb may be of use to comp.binaries.mac users and also may
help with some of our older files on Info-Mac.

We are getting replacements for our out-of-date Technical Notes. Check the
file /help/recent-files.txt to find out which ones, as there are too
many to list in a digest.

Subject: a request

I recently got a microexplorer in my office. For Mac II applications, I
expect my officemates also to use the machine. Is there any application
that will allow one to protect folders separately? With multiple users,
I need some way of keeping the users' documents private; e.g. it should
ask for a password to open a specific folder.

Please send e-mail to anupindi@isl1.ri.cmu.edu

Thanks,
Ravi

Subject: Default buttons on system alerts

One way to change the default button on system alerts (for example, ALRT -3996
"Replace existing file <x>?") is to use ResEdit to change the ALRT resource in
the system file.

If you open the resource and select the "display as text" item from the ALRT
menu which appears, you will get a panel enabling you to change this
default (via a check box labelled "2 bold") along with other information in
the alert template.  You will probably want to change all four stages.

A safer way to make the change is on a per-application basis (I did it to
Lightspeed C).  Copy the ALRT resource from the system file, paste it into
the application, and edit it there.  While the application is running, the
resource manager will check the application resource map before scanning the
system map, and so your modified alert will be displayed instead of the version
in the system file.

For more information on alerts, see Inside Macintosh...

Subject: Generic SCSI disk driver?     

I'm contemplating using one of several manufacturers' non-Mac disks on my home
Mac+ (with a homebrew cabinet which substantially reduces the incessant noise).
Depending on the manufacturer, i may have a separate controller or put a second
drive on the controller of my existing disk.  In either case, i'm going to need
a new driver, as even the existing one almost certainly won't handle more than
one unit.  This is no big deal for me, i've hacked much hairier disk code for
other machines (and already have the core of a disk diagnostic running on the
Mac).  But I-M VI explicitly does not explain a few things (c.f. p. IV-293) and
perhaps someone in this area has been through this before.  Nor does it suggest
how to implement partitions or multiple units, not to mention sundry `gotcha's.
The Tech. Notes emphasize the latter (esp. TN159), but don't really explain,
and APDA's package is explicitly incomplete (if it is even a disk driver to
begin with).  Of course, it doesn't deal with the issue of large disks or disks
shared by diverse individuals, in either case where partitioning is essential.

Does anyone out there have source code for a SCSI disk driver that i could look
at specific parts of (especially that which is not well-documented in easily
available form)?  Extensive comments take precedence over choice of language,
which are, in order of preference, `C', PASCAL or assembly language.

			-- Tovar 

P.S.  I know about SF&I and do not expect it to cover my situation.  Note that
i am not interesting in proprietary aspects of drivers, like how one can get
better performance than others on the same hardware.  Being out of disk space,
nor do i want to wait to get back-issues from some magazine in some language
i don't have and which probably won't do what i want anyway.  In other words,
i expect to have to hack the code, and if the result is reliable, i would
prefer to make the source code available for non-commercial use without fee,
or other solicitations.  I certainly don't want to use anything that would
preclude this.

Subject: Graphing Software for the Mac

David Swager asks about Mac graphing sofwtare...

   We use Cricket Graph for our graphing needs.  It does excellent xy
plots as well as many other types of plots.  Not only can it print out
on a laswerwriter, you can also use it to drive a plotter (such as an
HP 7475A) abd thus get color plots (the program supports color graphs,
even if you are only using a Plus or SE). I don't know the price, but
you can probably get it from one of the "1-800-Macsomething" companies.

Well, this program isn't shareware, but if you own a Hard Disk, you should
have it - Symmantec Utilities for the Macintosh (SUM). Not only will this
program allow you to partition your hard disk (and give you a special DA for
the management thereof), but it will also allow you to install an earmarking
file wich will allow you to recover files that have been accidentally deleted
with little to no hastle at all. It also "optimizes" disk files to speed up
the bootup proceedure.

I was given SUM as a Gift, and it was by far, one of the most valuable ones I
ever recieved...

Subject: HELP! virus?

     I am worried about a possible virus and was hoping my search can be
directed. A few days ago, my floppy has refued to run period. When a disk
is put in, it just sits as the mac thinks its turning, until eventually it
decides that the disk is unreadible. This also happens on startup, except
when I have done a PRAM dump, I get a bit of action (that high pitched loud
disk sound) but no true extended turning. I don't know the limits of what
a virus can do to floppy operations and how well it can hide in active memory
My SCSI 20 meg internal is running fine.
     Why might I think it is a virus? First the machine is only 5 months old.
Second I don't like the idea of buying a new disk drive. Third I am very
open to attack and have been doing downloading from various PD ARPAnet archives
During runtime, I have been receiving frequent ID 2 error messages and it
took 3 tries to get interferon to check anymore that 1 document without bombing
in my system, I have found 2 inits called "main" with a id=10 with an old Rx
and could not find them with Resedit. in my desktop I have some interesting
things including resourses called (not)=vir with the = really being a not
equals sign, and one that has no name at all. I don't have enough mac code
expirence to understand their codes though. Is there a way to make a virus
act on that first HD activity before the floppy is checked?  Also by the way,
The id=2 errors have decresased since my floppy died and I also have
virus running.
PLEASE RESPOND!

thanx,
David Klein

[The (not-equals)VIR resource in the Desktop file is the signature of
 Interferon. Many slapped-together programs don't have any signature at all,
 which would explain the nameless resource. -Bill]

Subject: Print Spooling w/o Multi-Finder for an ImageWriter II

Hello all!
	We have 8 Mac II's (6 with 1 Meg, 2 with 2 Meg) here at U.N.T. and
would like to be able to have a print spool running on each one without running
MultiFinder.  The Macs are on a AppleTalk network to a single ImageWriter II
and sometimes have to wait several minutes if the printer is tied up.  Is there
any such program (preferable PD or shareware) that allows us have the print
jobs spooled on each machines hard disk (40 meg) so that the user can continue
on?  We feel that the Macs don't have enough memory to justify running
MultiFinder for this job.  Please reply to me directly and I will summarize if
there is enough interest.   Thanks in advance....

The information that follows is a bit old, but I think it's still accurate.
What you've got is essentially a SystemError #64.  It shows up with the sad
Mac rather than the usual bomb alert box because, at that time in the
boot process, not enough of the system is present to display the alert.

The 1985 version of the "boot blocks" (read off your boot disk and
executed early in the boot process), used SystemError #64 to report that
the _InitResources trap failed.  This trap, among other things, opens
the System file and reads in its resource map.

Perhaps you have a bad disk sector within the System file, or maybe the
System file itself is garbaged.  I'd suggest trying to boot off a known-
good floppy, if you haven't already.  If that doesn't work, try clearing
the machine's parameter RAM:  Sometimes bad information in the parameter
RAM can affect booting in unexpected ways.  Good luck.

Subject: SYSTEM BOMB 42

	System error 42 is the "You can shut down your mac safely
now" message - or rather, it's the way the mac normally responds to
it.  The Finder generates this error; normally the Dire Straits
error manager has this mapped to the dialog with that message and
the Restart button.  If the mapping is destroyed, or if you have a
debugger installed that tries to be helpful by intercepting the
error, you may see something else.  I'd try a more complete system
file (the control panel should be irrelavent).
