Subject: [*] AddrePhone
This is a stack that can help you keep track of addresses and phone numbers.
Unlike the one shiped with apple, this stack have an index page that helps you
to scroll through and jump to any card. I also included phone number auto
formatters to help automate entery process. There is also an birthday check
option that checks one's birthday within 15 days.

Stefan Bilaniuk's rotating EARTH exists on just about all Macs, Spectre
GCR's, and Amax II's. FUJI_GADGETS is a rotating ball that has the
GADGETS logo on one side, and the ATARI FUJI on the other. This is
an INIT, goes in the SYSTEM/FOLDER and was designed for the Spectre
GCR Macintosh Plus emulator. Although it will work on any Mac, the
GADGETS and FUJI logos are obviously for the Spectre GCR Atari Macintosh
Plus emulator.

Subject: Creating color icons
I'm sure that many netters have seen the tremendous improvement that
using icon colorizers such as SunDesk brings to the Mac desktop. Color icons
really make the Mac desktop look great! I've been so impressed that
I decided to try my hand at modifing some icons and creating new color
icons of my own (based on their pre-existing black and white cousins).
Frankly, I've had only limited success. I can modify icl8s (color icons)
with the latest version of ResEdit (version 2.1) which has MacPaint type
tools. I'm okay as long as I don't mess with the ICN#(black and white)
bit maps of the icon. If I change them in any way, none of the color icons
are recognized after reboot. The entire desktop comes up with the generic
black and white ICNs.
Perhaps some netters can suggest how we can customize existing color icons
(icl8s) and create our own new ones either with or without SunDesk. If some-
one could create a brief tutorial it would be greatly appreciated.

Dick,
Something is WRONG and I don't think it can be your IIsi. Your talking
almost an order of magnitude difference here. It is probably your
Quantum HD. It could be one or more of the following three things (in
order):
1. Your interleave and driver type is not set for the IIsi. If you
received your HD formatted by the dealer, he may have formatted
incorrectly. Even the HD manufacturer could screw-up (My CMS20 Utility
wanted to format my CMS20 HD on my Mac+ at an interleave of 5! I got
maximum speed and performance manually setting my interleave to 3 and
using a MacSE driver!) Interleave varies with what machine you have and
what HD you use. With today's high speed drives it should be the
following: Mac+(3), MacSE(2), Classic(2 -I think), everything else(1).
The interleave on a IIsi should be set for 1. You can check the
interleave with a application like SCSITools (no longer in the sumex
archives but I do have it if you want it). If your interleave is wrong
or you just want to redo it, the HD must be formatted. Use the utility
that came with the drive, but don't forget to backup your data. You can
reinstall the driver (use IIsi driver) at any time.
2. Your HD is badly fragmented. I can't see this being the case since
I don't think you have had your system for too long (unless you've been
doing a lot of copying and deleting with your HD). You should run an
optimization program anyway.
3. Your HD is a slow drive. This is highly unlikely since the average
access time for a Quantum 100Mb is listed as 12ms. You could check the
average access time with SCSI evaluator in the sumex archives. It
should be around 12ms. By the way, if you try SCSI evaluator and the
average access time is much greater than 12ms, your interleave is not
set correctly. I guess I should have mentioned this in the first
paragraph.
I hope this helps and I'm not just tooting my horn.

Subject: Dollars and Sense
The recent discussion of Dollars and Sense interests me because I still
use D&S version 3.x. I tried upgrading to version 4 when it first came
out, but did not like the significant change--for the worse, in my
opinion--in the user interface. In version 3, accounts are kept
separately for each year, so that archiving is not necessary. Data entry
seems easier and cleaner to me. This year, I did have to generate new
accounts from scratch due to some sort of error that crept into my file
for last year, but that is the first problem of this sort I'd ever
encountered. Of course, I still have to use this version of D&S with
its own start-up disk and older version of the system files, but as I
have an old Mac 512ke sitting around, it's no big deal.
Questions: are there other people around who still use/prefer this
earlier version of D&S? Did version 5 stick with version 4's interface?
What additional features in version 5 am I missing out on?
Thanks for any information...Bob Chen, Brown University.

Greetings,
Thanks to all who sent me suggestions for getting System 6.0 to boot on my Mac
512KE with the Human Touch accelerator/memory board. It turns out that 6.0
requires an SCSI bus. It hangs indefinitely trying to initialize the SCSI bus
if none is present. I installed a Dove SCSI kit, and 6.0.7 is happy, and I am
almost happy. Excel 2.2 now runs, etc. BUT HYPERCARD 2.0 DOES NOT! It crashes
with an illegal instruction at 0000! Why it is branching to 0000 is a mystery
to me. Could it be related to a sound manager anomoly I've also noticed? When I
select the "Sound" CDEV in the control panel, I see the usual list of four
sounds, "Simple Beep", "Boing", "Monkey", and "Clank". But regardless of which
of these I choose, I just get a beep.

Subject: Mac Buyer's Guide for Apple Support Coordinators
Last spring I *paid for the privilege* of becoming an official Apple Resource
Coordinator and Apple Technical Coordinator after attending a seminar in
Houston. Prior to that, I was recognized by Apple National Accounts as an
Apple Support Coordinator for the Schlumberger Austin System Center.
Since *paying* $120 for the Resource Coordinator and Technical Coordinator
kits (made up of two huge binders loaded with product spec and sales
literature) I have received minimal support from Apple. Before I *paid* for
the kits, I used to receive lots of technical and resource help - including
the Mac Buyer's Guide! I never had to pay a cent for these materials, and
Apple benefited by increased sales volume. Apple has since reduced its
National Account support to nothing. I get an occasional AppleGram, but
nothing else. Big Deal! I got more than this before I *paid* for the support
kits!
Anyone else been burned by Apple by *paying* to support your users? What a
rip-off. Don't bother subscribing to the Apple Coordinator anything! It's
not worth it. Acutally, Apple was pretty shrewd in getting users to *PAY* to
become their "front-end" support. Makes one wonder what the Account salesmen
do with all that spare time!
In summary: You'll get much better support by asking questions of our
esteemed colleagues on Info-Mac. (And it's FREE!)
In my Humble, but accurate, opinion,

Subject: Mac IIsi RAM
In Info-Mac V. 9 #35, Alberto Ricci states with regard to memory configurations
of the Mac IIsi that:
>The possible configurations are 1, 2, 5, and 17 Mb (in this case you'll be able
>to use only 16 of the 17Mb, because of System 6.x addressing. However, System
>7.0 will use (by the way, A/UX already does) up to 4Gb (that's 4096 Mb)).
I have a IIsi configured with 17Mb of memory running system 6.0.7. Only 8 Mb
of that memory is addressable, although the system 'knows' about the other 9
Mb. The latter is lumped with the actual (about 1 Mb) RAM used by the system,
so that the 'About Finder ...' menu item indicates that some 10 Mb is allocated
to the system.
We have heard that software exists (Maxima? and/or Optima?) to make all 17 Mb
addressable within system 6.0.x. As Mr. Ricci notes, however, the addressing
problem will be eliminated with the imminent (?) release of system 7.0.

Yes the flyer from Falcon said Mac IIcx. An interesting comment was made in

perhaps it would explain why Falcon says they have limited quantities. And
what better way for Apple to clear out some older machines and get good
press by supporting the troops in the Middle East? Of course I could be cynical and say it was all motivated by profit and a lust for more Federal contracts.

1) Is there any way to allow "guest" access? That is, after selecting
AppleShare in the Chooser, and then selecting the Sun file server,
is there any way to connect to the file server as a "guest", instead
of a "Registered User"?
How do you all provide for 'guest' access (if you do) ?
2) Not related to the first question but, is it possible to
download configurations to the GatorBox from ethernet connected
Macintoshes? Or does one have to always download to the GatorBox

Subject: README Solution?
Along with Larry Rymal and Les Ferch, I have been participating in the
discussion about README files, and would like to contribute two thoughts:
1) Les calls for the various WP vendors to provide a PD version of their
programs (MacWrite, Word, etc) which can read and print. I think this
is a great idea, if it would work. I use both Word and Write/Now,
neither of which provide such a utility. I also have a "demo"
version of MacWrite II, but for this use, it is worthless because
the Print function is crippled. Write/Now seems to do a pretty
good job of translating most other formats to itself, so that's
what I'm using.
2) For those doing new documentation, who are willing to look at an
alternative method, I'd like to suggest DocMaker, from Green Mountain
Software. It is a shareware program which allows you to develop a
documentation package with complete control of text attributes, inclusion
of pictures, etc., then allows you to distribute that package as a
fully-functional self-reading document. I've created DocMaker documents
and received a number of them, and they are no problem at all.
I don't know if the package is in the archives (moderators?), but it
could be uploaded if it is not. If you're interested, let me know and
I'll send you the address and other information. BTW, I know that the
latest version is available on several of the commercial services and
through some user groups.
I have no connection with Mark Wall or Green Mountain Software, other than as
a very satisfied user of DocMaker.

Subject: Some bugs in HyperCard 2.0
>From: SWAT::NEUBURG 12-FEB-1991 13:05:37.88
To: NEUBURG
CC: NEUBURG
Subj: hbr
The following is a report on a couple of miscellaneous bugs and
programming errors I have run across in HYPERCARD 2.0.
-------------------
BUG #1 is the only actual serious BUG, and has to do with MARKED
CARDS. This bug is present both in the developer's version of 2.0
which was sent out around October and in the 2.0 currently being
shipped with new machines (as far as I can tell, these are
identical). If anyone knows how to notify Apple, I would
appreciate having this passed on to the appropriate personnel, as
it is fairly serious.
It is now possible, as you may know, to MARK cards, by setting the
card property MARKED of a given card to True, or by the command to
"MARK..." the given card; similarly cards are that have been
marked can be made unmarked by setting the card property MARKED of
the card to False, or by the command "UNMARK".
However, HyperCard behaves inconsistently with respect to the
question of whether a card is or is not marked. The bug is
complicated, so I have broken it down into different cases.
If any cards of the stack are marked, then HyperCard behaves
"correctly", as follows:
Commands such as "go first marked card", "go last marked card",
"go any marked card", "go next marked card", "go prev marked
card", will go correctly to the given marked card. In the case
where only ONE card is marked, all of these commands will go to
it, but commands such as "go second marked card" will correctly
cause HyperCard to return that there is no such card ("return" in
this discussion means, either directly to the user, if the command
was given from the msg box, or else by way of The Result, if the
command was given from a script).
But if NO CARDS of the stack are marked, then (this is the bug!):
Giving the command "go next marked card" or "go prev marked
card" from any card will correctly return "No such card" from
HyperCard; but the commands "go first marked card", "go last
marked card", "go second marked card", etc., will go to the FIRST
CARD OF THE STACK, even though that card is NOT marked, and even
though going to that card and asking for the Marked of that card
will correctly return False. Furthermore, the statement "there is
a first marked card", etc., will evaluate as "true", even though
no cards are marked.
Programmers are warned that in scripts one must avoid falling in
to the trap of supposing, just because it is possible to "go first
marked card", that therefore any cards of the stack are in fact
marked. The numerical test "the number of marked cards" always
correctly returns the actual number, and should be used prior to a
"go" of this sort. (NB: by the way, the Boolean test "there is a
marked card" is for some reason illegal, even though the statement
"there is a card" is legal.)
-------
The remaining bugs are programming errors in the scripts of the
developer's stack as distributed around October. The material
referred to here, the Help stacks and Power Tools, is NOT present
in the version of HyperCard distributed free with new machines;
but it was present in the developer's stack, and I presume that it
is present in the new "pay" version of HyperCard distributed by
Claris. However, I do not know whether the scripting errors in
question have been corrected in that version: users should check
the scripts.
BUG #2 has to do with HELP stacks for HyperCard 2.0.
The HyperCard Help and HyperCard Reference stacks have the
property that clicking on grouped text (marked with a gray
underline) will send the user to the corresponding discussion in
the Help Extras stack. However, this feature will sometimes seem
to fail to operate. This turns out to be because if the grouped
text occurs right before a Return, it sometimes has accidentally
been permitted to include that Return. Then, when the script
checks the style and font of the grouped text to see whether it is
a "Placeholder" or a "Glossary Item", it can be misled by the
style and font of the Return if the Return is not in the same font
and style as the text itself. The solution is to insert something
like the following lines into the CheckActiveText handler in the
script of the Stack of HyperCard Help:
if the last char of thePhrase is return then
put char 1 to (the length of thePhrase - 1) of thePhrase into
thePhrase
subtract 1 from word 4 of theChunkOfText
end if
These lines, which will remove the final Return from the text to
be evaluated, should go after the line that reads "put the
clickChunk into theChunkOfText".
------
BUG #3 has to do with a SUPER GROUPER script.
The repeat loop in the "on spaceObjects" handler in the Stack
script of the Power Tools stack should read:
repeat with count = 2 to NumberOfItems
get item count of ObjectList
if direction is "Horz"
then set LEFT of it to (RIGHT of item (count - 1) of
ObjectList) + spacing
else set TOP of it to (BOTTOM of item (count - 1) of
ObjectList) + spacing
end repeat
The loop in my copy was written incorrectly, so that spacing did
not work properly (the objects were caused to overlap, because the
LEFT of it was set with respect to the LEFT of the previous item.
------
Hope this proves helpful to people.

Subject: System 7, IAC, and DTP
Hi y'all,
I was just thinking about system 7's inter-app communications(IAC) stuff. I
can see one heck of a page layout program. The current versions of Pagemaker
must understand the file format of an article they import. For example, I
think pagemaker can read Word files, mac write II files, etc.
Well, with IAC, that could be different. A user decides where a document is
to be placed on the page (including size of bounding box, columns, etc.). This
new page layout program then boots the app who owns the document and tells it,
via IAC, to render the document in the specified bounding box. The page layout
program need never know about the format of the data on the disk.
Of course, I'm just a low-life when it comes to the world of DTP. I have
used Pagemaker,.. breifly. More importantly, I don't use it everyday, all
day. My idea, above, would take a lot of memory (many apps up and running at
once) and also require quite a bit of processing power if things are going to
go at a reasonable speed (ie -- each time you flip a page, all the sections
would have to be redrawn by the owner programs).
But it would be nice. If the IAC format was made public, everyone could
write their programs with type setting build it. Perhaps programmers wouldn't
have to pay attention to detailed page layout for each program they write. Just
let the user do it (this means something cheaper than Pagemaker, I suppose)
with this layout program.
But hey, for this IAC stuff, are there going to be a bunch of accepted
(public) formats for messages (not just in the DTP area, but in word
processing, communications packages, utilities, etc.?).
Idle hands are the devil's hands,
Gordon.

Subject: Terminating harddisks
There has recently been somebody who has told that the Macintosh computers
have internal termination for the SCSI bus.
THIS IS NOT THE CASE
The internal termination in Macs consists of the 3 resistor packs that is
fitted to the internal SCSI drive!!!.
If you want to remove the termination of a drive, then you must pull up the
resistor packs, which is 3 black or yellow IC-lookalike with only 1 row of
pins. They are found just behind the drives connector. You can remove them
with some controlled violence, as they are often mounted in some very small
holes in the PCB which does not look like a socket.
The problem in making an internal drives external is to get a PSU and to
change the SCSI ID for the drive, but this is another story.

TinCan is written by George Furnival <Furnival@YaleVM.YCC.Yale.Edu>
It offers a pretty good VT100 emulator (and a few others, I'm at home
using an old Apple 2, so I haven't all the options handy :-)
TinCan is to the Macintosh what YTerm is to the PC. Along with PC Trans
running on a VM/CMS mainframe, these two programs provide rather simple
(easy to learn how to use) file transfer protocols (text, binary, MacBinary)
with appropriate CRC error checking.
XModem is supported (at least in the beta version I'm testing :-) and
George is busy adding Kermit too (coming soon). There is a discussion
list on BITNET (TINCAN-L). Docs are shipped on disk with the program.
George spends more time improving the program than writing docs, but
TinCan was written for the Mac from the ground up. As with most Macware,
you can get along fine with out paying much attention to the docs.
