Subject: [*] Battle of Midway Demo (strategic wargame)
This is a demo-version of the Battle of Midway strategic wargame
>From Wartime Simulations/SJP Enterprises. This demo-version has
is limited by alowing only 20 movement turns and only 1 scenario
to be played. But it is still playable.
It is a typical 2 player board game implemented on the Macintosh
using hidden movement. It simulates the attack on Pearl Harbor
during WW II, and includes both naval and air operations.
There are included some instructions in the game, but it is not
mentioned that you have to click the thick horizontal bar in the
bottom of a sector to return to the main screen and enable menus
for the next move.
I have been mailing a chineese in USA, and he should have got a
copy mentioning this in the instructions. If this is correct,
then please contact me.
The game has been created by Steven J. Ponzo of Wartime simulations
at a request from me, but I have never (yet) bought any of his
products, I do not know him in person, and I do not get any money
out of this distribution.
Steven has given permission to widely distribute this program to
other networks, so you can do this if you want. I can only place
it in the sumex-archives, as I have only access to the InterNet.

Apple has unveiled its new models, and I'm doing a little comparison
shopping. I've listed below Apple's new "educational prices" as
provided by the University of British Columia Bookstore, and confirmed
by an Apple Canada rep during a computer fair on campus.
I'd like to find out what the educational prices are at American
universities -- especially those in the Apple Consortium -- and at
other Canadian institutions if they differ from UBC's. If one of you
knows where this information is available for anonymous ftp'ing, will
you please advise? Or if you can provide prices for your own
institution, I'll summarize findings for Info-Mac Digest readers.

I have a Mac at work, and a PC with a modem at home. I tried to download some
Stuffit files from ZMAC on Compuserve (source code from MacUser's Power
Programming). I transfered them to the Mac using Apple File Exchange, then
used ResEdit to change the file and creator types to SIT!. When I tried to
unstuff the files, Stuffit told me they were damaged and to try to salvage
what I could. Then it said there was an unexpected EOF and couldn't read
the SIT file. Can someone help me get this to work?

Subject: Color Games
There have been several messages in the past about color mac games
or lack there of. I have some recent tidbits to impart on the subject.
Might & Magic II Color
----------------------
The color upgrade for the M&M2 is now available. The new version
sports totaly redrawn 8 bit graphics! Very nice. Runs under Multifinder
and 32bit quickdraw. Nice sound. The color version is an upgrade of the
b/w version. Yes, that's right you most first buy the b/w version and
then send in a coupon and 27.50 to recieve the color version.
The b/w version has documentation trivia protection...
"What is the 2nd word in the last sentance on page 54?" Fun, Fun, Fun.
But there is a patch for v1.0.1 of b/w M&M2 that removes this
"Feature." If you have the b/w 1.0.0 the upgrade is free, just
send your disk a letter requesting the most recent version.
With the color version you also get a hint book. Great, bonus
included in the upgrade. But this is not the case. The book
is only included as additional copy protection. The color version
requests a passwords from the clue book! I wanted to keep the clue
book sealed, but no I have to look up a code word evertime
I run the game. This is not very fair, it is quite easy to notice
some detail while looking up a code. One would think for the tune
of $65 that your could get a version that wasn't protected.
I spent much less then $65 for the color version of SimCity.
Also the clue book can be purchased at software stores, and of course
photo copied. If someone can get a copy of color version they can
also get a copy of the manual.
Is the program worth $65?
Yes, but the copy protection is not called for at that price.
Maybe someone will create a patch for the color version?

Thanks to everyone for their responses.
Summarizing....
1 -- I wanted the DA for a friend who recently (grudgingly) obtained a Mac
and misses his Unix machine. The DA is a gift for his upcoming 50th
birthday.
2 -- The DA in question is called Rasnix. It is not available on the Info-
Mac archives, but other places (notably the BCS CD-ROM) have it. It is
limited in what it can do, but it does still work. Rasnix is freeware.
3 -- Another utility called CLIM may do this as well, but I have yet to find
a copy of CLIM to verify what it does.

archive site (sumex, of course), came the file clockadjust.sit. UnStuff into
ClockAdjust and ClockAdjust.doc. CDEV works fine. Documentation (MacWrite
file) is trash. MSWord (3.01 & 4) beeps - file error encountered - and skips
that part of the file. I went thru the whole file and got nothing more than
three of the illustrations out of it. Does anyone know who the author is, or
have a good copy of the file? I also tried simtel, rascal and a BBS I use,
and all have scrambled copies of the documentation!

The disks (NO manuals) were shipped to user groups the first week of
October (by Apple). I'm a dues paying member of two groups (both have
the five disks with Apple labels on them).
If rumors are true, manuals won't be available until the middle of next
month (unless, perhaps you buy one of the new Macs; I understand
HyperCard 1.2.5 won't run under System 6.0.7 unless the sound is set to
zero).

Subject: Hypercard 2.0 and Labels
In the office where I work the main use of Hypercard 1.2x was for
printing labels. Hypercard did a superb job of printing standard
33-to-a-sheet labels on the laserwriter (up to 6 lines), with the
default "label" Report setting. (Of course, "larger print area" must be
selected in the Page Setup dialog.) But there were two minor
problems with label printing with Hypercard 1.2x:
1. Due to a bug, only one copy could be printed at a time. This
meant that if you want many sheets of return address labels
each sheet must be printed individually.
2. There was no way to print just certain labels from a stack.
It was all or nothing.
As Hypercard 2.0 fixed these two problems I decided to try the
new version for printing labels. However I immediately discovered
that there was no preset equivalent to the default from the old
Hypercard. After struggling for half an hour to set up a report
template equivalent to the old default (6 lines of 33-to-a-sheet
labels, to print on standard label sheets), I gave up.
If it can be done, I sure can't figure out how.
If anyone out there has had success in creating such a template,
please e-mail me a copy of a stack containing the template.
Meanwhile, it's back to Hypercard 1.2x for us.

Subject: large monitors
We have over several years used two different "large" Mac monitors.
We began with Radius full page monitors on two Mac Plus(es). One
was DOA but quickly replaced and for two years they have been very
good monitors. One is now dead and I will not buy more Radius mon-
itors because of the Radius refusal to service this one except via
the middle man where we bought it.
We also have three Mirror PixelView II monitors around, one on a
plus and two on SEs. One failed early but was quickly replaced with
no hassle (our relationship with Mirror has been excellent) and all
have been very sharp and the monitors are much loved. Unless you
are (or have access to someone ) very good at component handling I'd have
to say that the Mac Plus interface on both the Radius and Mirror
mitigate against using the Plus. I recommend against it here when
asked. The SE is a cinch to install and so far has been solid.
Taking them away from the secretaries who use them would be a dangerous
act. Taking mine would be more dangerous yet.

Subject:Laser Formatting w/o Printing
You want users to be able to format for a LaserWriter but not be able to print
to a laserWriter. Here's my suggestion.
Take the LaserWriter file from a System Folder and open it with ResEdit. Go
to the DITL that has the print 'OK' button in it (DITL -8191 on my LW driver).
Select and doubleclick on the OK button. Change the Enable to Disable and
for grins you might want to change the text in the OK button from OK to Not OK
so that users will get the idea that something is a bit different.
Also, so that you don't get too confused with your mutant LaserWriter, change
it's name in the Finder from LaserWriter to something like Format LW and then
in the Get Info Window, Lock the file so that users don't change the name.
With the file locked, you will not be able to select a different LaserWriter
in the Chooser (assuming you have multiple) but since you cannot print anyway,
it won't matter.
Spread your Mutant LW driver to all the imagewriter Macs and they'll be able
to do everything except print.
Have fun

From: Greg Wimpey <GWIMPEY%TRINITY.BITNET@forsythe.stanford.edu>
Subject: Limiting LaserWriter to one copy
Fred Condo <condof@clargrad.bitnet> recommends changing the LaserWriter file
with ResEdit to prevent users from printing more than one copy. This may work
fine for your average ResEdit-ignorant users. However, there are two ways to
defeat this:
1) Boot up with a floppy with an unaltered copy of the LaserWriter file.
This is possible for anyone to do, unless you have somehow restricted the
ability to boot up with floppies (e.g.--using AME to disallow mounting of
the hard drive when booting from another disk).
2) Use ResEdit to change the file back.
This is not as easy as #1, but it will work. Of course, you could lock the
file or make it invisible, but these methods are no real obstacle to the
truly obnoxious user. Of course, you could limit access to the file with
a program like AME(I think). This, however, just adds another adminis-
trative hassle.

They make a product called ... HyperBoard ... that will allow you to probably
do whatever you want with real world I/O. It is a small A-Bus card (4x5
inches) that has a serial port connection to the Mac. It has Intel BASIC on
board and it communicates with all sorts of A-Bus cards that are made by
another company. I bought HyperBoard, an 8 port A/D card, a 2 Stepper Motors
Control Card, a stepper motor, and card case for under $500. I have a
HyperCard stack that loads BASIC into the board when I first turn it on, then
it controls the stepper and grabs voltage readings. I am plotting light
intensity vs distance. They have quite a collection of A-Bus cards available
and it is really quite easy to hack together exactly what you want. I am
converting the stack into a SuperCard Standalone and eventually it will be a
"real" application. You can get battery backed up program memory for the
HyperBoard. All in all, it seems like a good way to grab real world data.
You will need someone to find the actual physiology sensors and interface that
into the A/D card(s) but since channel gain is variable with resistors, that
is not going to be such of a problem.
Let me know how it goes.

Subject: Security for a Mac Lab
We have recently installed a Lab containing several MacSE's each with a hard
disk. The problem is the students have been malaigning the information on the
hard disk. We are currently running Empower, but it doesn't prevent a guest
user from creating a folder, it allows the guest user to move existing folders
into the newly created folder even if administrator owns the folder, and it
allows the creator of the folder to set the access levels on the new folder.
This creates a management nightmare. On a daily basis someone must reset the
systems to "normal". What I am looking for is a method to control the write
access to the disk, and to automaticly remove any student files from the disk.
The ideal situation would be the following. A student logs in and a temporary
folder is created. All the student's work is placed in this folder. The
student would only be allowed to write to this folder, and any files or folders external to this temporary folder could not be moved. When the student is
finished the system would prompt him or her regarding saving the files to
a floppy. The student could then choose to save all, save selected or save
none. The system would then execute the appropriate write statements, remove
the temporary folder and log the student off. Does anyone know of anything
out there in the Mac world that would give me all or some of the desired
features? What do other schools do about security in their Mac Labs? Thanks in
advance for any input. Please respond to me directly since I am not a member
of this list.

Subject: Writing a spreadsheet
Greetings.
I am looking for help writing a spreadsheet type program.
If anyone is fimiliar with Datasheet for the Apple IIe, I am rewriting it for
the Macintosh. Datasheet is a "baby" spreadsheet program designed for freshman
level physics students. It is not very powerful, but has the features (and only
the features) needed in basic data analysis and plotting. It has the advantage
of being easy to learn and use. (Remember it is designed for freshman who have
had little computer experience.) Why not write a few macros for a popular
spreadsheet? $$$. The only spreadsheet the college has a site license is
Microsoft Works. Yes, easy to learn and customize, but the plotting
capabilities are not great. (This may still be the answer, if this project
is not susessful.)
I am currently using Lightspeed Pascal. The List Manager provides most
of the bookkeeping in the handling of cell addressing and manipulation. But the
price is speed. The initial design of Datasheet provides 6 columns by 250 rows.
(Any more than this, and the student would not be using this program to begin
with.) At this size, even streamlining as much as possible, short of writing in
assembly, it takes seconds to fill the screen. (Not a major concern, but a
bit annoying.)
What I am looking for is some help with the List Manager or other input
on how to go about building spreadsheet functions from scratch.
