Are there any project management packagers available for the Mac that
are more powerful than MacProject?  I think my boss is about to
recommend the purchase of an IBM PC because he claims that MacProject
wont do the trick.  I think he's full of it and is just lookin for an
excuse, but I would love to shut him up again.  So far I've countered
every argument he's presented for getting one of the "other" machines.

While I ahaven't seen their stuff, you might contact Micro Planning
Software USA, 235 Montgomery St., Ste. 840, San Francisco, CA 94104
[phone]. They publish MicroPlanner and Micro Planner Plus ($395 &
$495) & Micro Planner Project Exchange, an add-on module to the above.
From descriptions, it appears to have many features lacking in
MacProject (including swapping files between the same company's IBM
version and the Mac version...;-)).

You might even ask your boss if he'd like to purchase the Mac version
for you, and get the IBM version and a clone for himself and see who
sets it all up first! (hehe)

I heard one complaint about MacSafe, probably on one of the networks,
but I'm sorry I can't remember exactly where it was.  This is one
program you *don't* want bugs in.  Alternatives are Hard Disk Partition
from FWB software, which provides low-level password protection, and
MacServe from Infosphere, which provides good password protection along
with the networking functions.  TOPS also provides password protection,
on a folder basis, unlike the others, which do it on a logical volume
basis.

Subject: interrupts
Date: 19-MAR 03:05 Programming Techniques

I just recently reviewed the chapter in IM on interrupts for a project
that i'm working on and ran across something I found rather mystifying.
The SCC and VIA are tied to the 68000 interrupt pins such that the SCC
generates a priority level 1 interrupt, and the VIA a level 2 interrupt.
If both are interrupting at the same time this generates a level 3
interrupt. According to IM the Mac responds to a level 3 interrupt by
merely executing an RTE.  I checked it, and sure enuf, that's what it
does!

Now it seems to me than since the RTE instruction does nothing about
removing the source of the interrupt, the processor will just get
interrupted again right away and be caught in this loop forever.  Is it
possible that either the SCC, the VIA, or both are removing their
interrupts after some short time interval, or is there something else
going on that i'm overlooking?

Joe

From: PEABO
Subject: RE: interrupts (Re: Msg 1350)
Date: 19-MAR 12:31 Programming Techniques

I don't have a VIA data sheet handy, but the way priority interrupt
decoders usually work, the levels don't get ORed.  Instead, the highest
priority signal going into the decoder causes all the lower priority
signals to be temporarily blocked until the high priority signal goes
away.

From: JOSEF
Subject: RE: interrupts (Re: Msg 1351)

yes, that's the way it usually works, but in this case, there's no
decoder. The SCC interrupt is tied direrctly to IPL0 and the VIA
interrupt is tied directly to IPL1, and sooner or later, both of these
are bound to get activated simultaneiously.

Word 3.0 has some major problems saving large documents in Word 1.0
format, ( which happens to be necessary for interchanging documents with
PageMaker, Scriptor, and other applications that read word files). Large
documents will often get scrambled in the process. The cure seems to be
(other than using small documents only) to save in RTF (Interchange)
format, close the original document, open the newly saved document, and
save it in 1.0 format ... yecch! Some help may be on the way, as
microsoft _finally_ agreed to release the details of word 3.0 format to
other developers (although MS admits it's a very bad mess).

Has anyone had any problems using DiskExpress with the new Sys/Finder

my main drive, it stops in the middle of the optimization process...or
hangs, I should say.

I rebooted by pressing the programmer's switch, and surprisingly didn't
lose anything or have any problems as a result (after my problems of a
few months ago, I don't do anything like express without an up to the
minute backup, so I wasn't worried about losing anything).

So this might be a bug report, as DiskExpress works fine when I replace
the System/Finder with the 3.0/5.3 set...but any clues as to why it
might cause a problem?

If I distributed their libraries, I would be happy to display a
copyright notice.  If I link MY code using the software I bought from
them, they would have to sue me first.  Their product is sold for the
purpose of being linked with other code to produce a NEW product.  If
your/their argument prevails, then the copyright/patent owner of
anything used as a component has rights to the whole, even when the
product doesn't resemble the component.  Nonsense.  DuPont has no rights
concerning clothing made of orlon; the manufacturer bought the orlon and
made cloth.

What they are looking for is advertising, not protection; and I doubt
that a court would recognize my obligation to advertise the component
any more than it would force me to include the name Kodak that appears
on my negatives on every print I make.

They are entitled to an internal copyright notice if it's part of their
code. I'm not even sure if they could legally prevent me from removing
THAT during the process that creates my product.  Does anyone know of a
precedent (in the software industry)?

Welcome to the fun and exciting world of 2400 baud telecommunications.
The problem is probably NOT your modem.  I get the same interference
when using non- local (intra-state) phone service.  Since there is no
error correction protocol in these "affordable " 2400 baud modems, you
are operating under extreme conditions for a telephone system virtually
unchanged in fifty years.  Your mainframe can probably connect at either
8 bits, no parity, one stop bit, OR 7 bits, even parity, 1 stop bit. Try
both protocol s.  Fortunately, you can usually backspace the offending
character away.

You commented on a press release from MacNeal-Schwendler Corp concerning
a new stress and vibration analysis program for the Mac, called MSC/pal.
 We received a demo copy at the San Francisco MacWorld Expo, and were
VERY disappointed with it.  The program has been ported over from some
other computer and absolutely DOES NOT use the Mac user interface.  You
have to type in everything you need to enter just like you were
operating on one of those other computers.  No matter how good the
technical computational capability of the program is, we simply _will
not use it_.  The MSC people told us last week that they would be
releasing a new version with "some of the Mac interface implemented"
later this spring, but for the prices they are charging ($1000+), they
should implement (and fully test) a _full_ Mac user interface.

I sent you a long reply which I will not repeat here.  The Davong is a
fast and robust implementation of the serial port hard drive, which
leaves you with a whole another port to choose printing, modeming, or
AppleTalking from.

I forget the patch now - a bunch of NOPs (4 or 6) instead of dividing
and multiplying by a global that changed with the new ROMs. I may post
it if I find it, but I'll USnail you what you need.  I'm a sucker for a

Raines, I notice your special interest in the surge-suppression issue. I
too have been particularly interested in this. Normally, the power here
is relatively clean, free of major anomalies, and is not prone to
disturbance from outside influences . At one of our meetings a year or
so ago, we had a fellow come in from Clark County power co., who had run
LOTS of tests on power conditions in the SW Wahsington, NW Oregon area.
In addition, there were quite a few tests of surge protection and power
line conditioning equipment. Results of tests showed that the TrippLite
Isobar units were among the best (No.2). I don't remember the #1 unit,
but it was a lot more expensive. The 2 "Extra Protected" sockets on the
top of the line DataShield also rated well. One of our more technically
oriented members steadfastly maintains that surge protection is pretty
much unnecessary for the Mac. I can't say that I agree. Statistics show
there are too many power anomalies which affect microchips in unknown
ways. However, it does seem to be true that most so-called surge
protectors do not provide much protection - certainly not on all three
wires - and few offer adequate shielding from noise. Along similar lines
is the need(?) to protect phone lines from surges and noise. I read an
article from somewhere in the midwest (where they have lots of
electrical storms) that outlined a host of problems associated with
phone-line surges. Since the serial ports have _NO_ protection
whatsoever, a surge of this type can permanently fry your Macs innards.
Fortunately, most of us on the west coast do not experience such things.
Nevertheless, a good protector is cheap insurance, as far as I'm
concerned. Anyone who uses a computer in a large office building, in
which the power is subject to wide fluctuations, ought to have some
protection. But I have not seen any studies done which might support
this hypothesis. It would be good to see some research showing just what
environments merited what kind of protection - and to what degree. Short
of doing any research, which would put the matter in its proper
perspective, there are just too many scare stories and wild theories to
substantiate manufacturers' claims of the necessity for various kinds of
protection. Keep me posted - and let me know if I can help gather info.

Subject: potential problem in lightspeed DAs
Date: 22-MAR 04:33 Programming Techniques

After about 48 hours in the twilight zone, I discovered a potential
problem which can occur in DAs written in Lightspeed C (and possibly any
DA, for that matter).

background: DAs written in LSC can have global variables.  The compiler
generates references off of A4, which is loaded by the glue routine
before it calls main().  The area itself is initialized from the DAs
DATA resource at the open call (also by the glue).  If the data area is
present, the glue locks it before each call to the driver.  The LSC
manual (chpt 9) states that you can unlock the handle between calls if
you want to be nice to the rest of the system (and you can live with a
floating data area,ie-no stored pointers across calls).

Anyway, I was doing this in a new DA I'm working on and was experiencing
all sorts of bizarre behavior that seemed to be related to using
dialogs. I finally traced it down to the fact that somehow, both the
DATA and DRVR segments were being unlocked somewhere in the middle of a
call to the DA! More tracing revealed that unlocking was happening when
I called ModalDialog.

After more than a bit of thought, I realized what had happened.
ModalDialog calls SystemTask, which calls the DA with update events.
This second, recursive entry was unlocking the DATA area and worse,
since I was running without dNeedLock, the DRVR's code segment.

The solution was to use an up-down counter.  On each entry to main(), I
increment the counter and set the dNeedLock bit (which inhibits the glue
from unlocking the code segment after main() returns).  And just before
exiting, I decrement the counter and, when it hits zero, unlock the DATA
seg and clear the dNeedLock flag.

I've never run across anything that mentiions the possibility of this
kind of recursive entry into a DA.  Could be a source of problems
elsewhere.
