    Is there any way of knowing to which file a specific disk block
belongs?  There are three blocks on my hard disk (MacBottom HD45) that
are unreadable.  This is established by using disk verification programs
(Disk Express, MacZap) and disk/file editors (MacZap, MacSnoop).
According to MacZap (using the Volume Information window), two of these
blocks are in an area that is currently unoccupied.  I suspect they used
to belong to a text file that got trashed recently.  The third is part
of some file.  How can I find out which file?

    I talked to customer service at PCPC, and they recommend
re-fomatting the disk to get rid of the problem blocks.  I have a recent
back-up of the HD, but I don't want to restore a faulty file after
re-formatting.

    Can anyone point me in the right direction?

>My SE's 20SC died on me about two weeks OUT of warranty! The finder

    My SE died almost exactly 2 weeks out of warranty (2 weeks ago!)
Coincidence?  Planned obsolecence (sp?)?  Actually, the analog board was
the culprit, and it even turned out that it wasn't directly Apple's
fault.
    For about 3(!) days I had an ultrasonic humidifier (using Cambridge
water) about 5 feet from the mac.  This thing puts out lots of this
white  powder stuff (minerals from the water) that lands on everything.
It had  never been a problem with my MacPlus, except to turn the screen
hazy sometimes.
    Unfortunately, the SE fan apparently sucks this powder in like crazy
and dumps it all over the inside!!!!  When the repairman opened it up
the powder was all over the place!  It got bad enough to short out the
analog board somehow!!!  At least the new analog board had the quiet
fan.

    The moral of the story: Don't Use Mac's in a Room with an Ultrasonic
Humidifier!!!!  It can be deadly.  3 days of use killed my mac (and it
didn't die until about a month later).

Subject: Qkeys/Tempo features?
Date: 14 Mar 88 23:06:00 GMT

I'd like to know whether the following 2 features are available in
Tempo; I am sort of disappointed that they are not in Quickeys.

1. All Qkeys macros are activated by one key (plus optional modifiers
   pressed at the same time).  If my leftmost two fingers have to
   struggle for modifier keys, I would rather use multiple keys in
sequal.
   It is also more meaningful this way.  E.g. I would define CMD-W N
   for starting up WriteNow, CMD-W P for Word Perfect ...

2. The Click define in Qkeys are too limited. At least, it should
   support provide checkboxs for whether other modifier keys are
   effectively pressed.  Right now, you cannot use Qkeys to represent
   many finder short-cuts which required modifer keys.

Furthermore, it really needs some mechanism for passing arguments to be
a real macro utility.  But, this is somewhat out of general audience's
scope.  Then, to be ultimate programmable and powerful, an emacs-like
lisp or hypertalk like  ... ?

I don't have an answer for the first problem, but I have one for the
second. Use MacTools (from Copy II mac) to verify all the individual
files.  The one that doesn't verify contains the bad block.

I just tried it with copy II mac 7.0 and it was a pain.  I had to click
OK after every file.  I hope that you can come up with a better way.

 Hiya. Does anyone know of a term program with TRUE ANSI.SYS emulation
that'll run on my Mac SE? I need ANSI, -not- VT100, as my VT seems to
only handle about half the ANSI messages. If you've passed that test, do
you know of a Mac term program with Zmodem? Yes? No? Does it exist?

 The second part of my post involves file servers. Does anyone know of a
Mac binary archive accessible through a file server (NOT Ftp!)? If so,
where's the address so I can send it an index command? Thanks,

When I posted my original note asking for hard drive recommendations, I
got a reply from a fellow who works for Micah drives, recommending his
product.  It sounds like a great deal - for $649 you get a 20 meg drive
with auto-park on powerdown, and 10 meg of PD software, not to mention a
2 YEAR warranty.  Sounds great, but I've never heard anything, good or
bad, about Micah drives.
    If any of you out there who aren't affiliated with Micah have
experience with these drives, I'd appreciate hearing about it.  I just
can't bring myself to buy a product I know nothing about.  The warranty
is great, but having a product in the shop for two years, even if it's
for free, is no great deal (and this has happened to me before with
bargain deals, so I'm especially wary.)

Thanks in advance.

I am about to release a PD video game that I would like to make
multifinder compatible.  It works fine on a Mac II; and on a Plus or SE
most of the time.  The problem is that on the 68000 machines I need the
speed of page flipping, and am using the whole screen including menu bar
and the secondary graphics screen.  First, does anyone know how to get a
window to overlay the menu bar?  Second, has anyone tried to make MF
deal with the second screen?  I think I can accomplish the second if I
get the first.

MultiFinder changes low memory variable MemTop (accesses by routine
TopMem()) to a number *approximately* equal to the size of system heap +
the size of the current (i.e. calling) application's partition.  The
rationale behind this is to "convince" older apps that this is the size
of the machine.  Note that this changes MemTop to be a size rather than
a pointer; the 2 were equivalent before because RAM starts at 0, but
most apps used it as a size.

Hopefully an application does not need to know the real value of MemTop,
or even a fake one, but if it does it should only need it for purposes
of displaying machine information.

Anyway...it seems that we were remiss in the first release of the
MultiFinder Development Package.  There *is* a MF temp memory call for
MemTop, as follows:

    /* MultiFinder dispatch trap */
    #define OSDISPATCH                0xA88F

    /* Routine selector value */
    #define mfMemTopSel                22

    /* Macro that the gets put into your source code */
    #define MFMemTop() \
    cTWMemTop(mfMemTopSel)

    /* And the actual trap that gets called */
    pascal Ptr cMFMemTop(SW)
       short        SW;
       extern OSDISPATCH;

This info will be put in the MultiFinder documentation ASAP, along with
the corresponding interfaces for Pascal and assembler.

Does anyone have any experience writing programs to use the new Apple
MIDI interface?  What I would like to know is if Apple has provided any
kind of driver software that makes use of the interface fairly simple
(ie: you don't have to write your own driver/interrupt routines).

I've been thinking of doing some MIDI stuff but I don't want to have to
write all the interrupt routines & such myself.  So, what does Apple
give you with the MIDI box?  Have they integrated MIDI support into the
operating system yet (I seem to recall reading something about this, but
I'm not sure where).

Please reply via mail if possible.

There isn't anything that's very clean, but there are a couple of things
you can do: (1)  Set the menu bar height to 0.  HyperCard does this to
get rid of the menu bar.  Like HyperCard, your app will have to restore
this when it gets a suspend event (although if you get rid of the menu
bar and your window covers all others it might be difficult for the user
to initiate a layer switch -- but you should still handle all this). (2)
 Change the clipping in the wmgrport.  This is pretty gross, and could
have some nasty side effects.  Therefore, option (1) is much more
preferable, given that you're determined to do this.

Are you really sure that you want to get rid of the menu bar?  This has
some undesirable effects in terms of user interface, especially under
MultiFinder. At the very least, it would be nice to allow the user to
decide whether the menu bar is hidden.  In terms of page flipping, I
think if you're tricky enough you can still make the menu bar work
correctly.

>Second, has anyone tried to make MF
>deal with the second screen?  I think I can accomplish the second if I
>get the first.

Actually, this is the tough task...really tough.  MultiFinder cannot
allocate a new screen (or sound) buffer at application launch time.
This was possible in the old single application mode because the entire
memory state above the system heap was recreated from scratch each time.
 The only way to really make this work is to have an init that allocates
the second buffer before MultiFinder starts up.  This is difficult to
write and forces the alternate buffer to always be allocated.

Note that this is only a problem on MacPlus and SE; the page flipping on
the MacII is done differently (since you have to access the video driver
on the card directly).

A final note:  Your application would become *much* more compatible in
all respects if you could tune it to the point that you don't need to do
page flipping.  I guess that's become obvious just from the fact that my
response was pretty obtuse...or else it's just me.

Are you sure Hypercard *just* sets the menubar height to zero?  I could
imagine it does this in addition to setting the clipping of the wMgrPort
etc., but notice that the bottom corners of the screen become
rectangular when you swtich the menubar off.  Hurm.

In either case, I thought you also had to modify the grayRgn (Which you
can now get at through a routine instead of using a low memory global.
Hurrah!) or maybe both the grayRgn and the wMgrPort clipRgn.

PTCH resources contain patches that are installed early on in the
bootstrapping process.  So far as I know, they're just naked code. The
PTCH executed is selected according to the ROM version number of the
machine that's starting up.  This way new versions of the Apple system
software can contain different patches for different machines with
different ROMs.

I doubt that Apple will ever officially document the format of PTCH
resources.  They're not there for 3rd parties, just for Apple use in
patching the system.  Outside developers are expected to use INITs,
which are much more flexible, easier to install, and generally approved
of.

Why exactly do you *need* this information?  I'm curious.

Does anyone know what algorithm the Apple Laserwriter uses to smooth out
bitmap images like Macpaint files. If you do Print Draft, you get one
quality, if you do Print Final you get a much more smoother image. The
reason why I am asking is because when I take a macpaint file and put it
on my Dec Ln03 (laser printer, 300 dots/in, same as laserwriter) my
image resolution is same as what I get from Print Draft. If anyone knows
the answer please Email it to me. Thanks in advance

   I've just bought a CMS SD60, and so far I have no problems. However,
I have a few questions:

1. I remembered a few people mentioned that it comes preformatted with
1-3
   interleaf. However, mine came preformatted with 1-5 interleaf, and
the
   default (which according to the manual is the optimal) interleaf is
1-5
   for both Plus and SE, and 1-3 for MacII. Is the software that came
with
   my hard disk an older version? It seems that its version is v3.2m, is
   this an old version?

2. The formatted capacity of SD60 is supposedly 62.40MB. Using "Show
Volume
   Data" option, the total physical blocks is shown to be 126784. Now,
   62.40MB == 62.40 * 1024 * 2 == 127995 blocks. What happens to the
other
   1011 blocks (about 505 KB--which is quite large)?

3. The manual mentioned that there are 8 dip switches. However, it seems
   that I can't found those dip switches on the backside of the cabinet.
   Instead, there are three jumpers (they look like jumper to me) near
the
   fan. Are those, which seem like jumper to me, the dip switches
mentioned
   in the manual?


   Thanks in advance.
