The release version of DIMMER is compatible with MACROMAKER. Dimmer is
part of SCREEN GEMS (Microseed), a commercial product.

I would like to hear from people who have installed 3270 emulation cards
in a Mac II. Do any of the cards support 3279G graphics?.

I'm having an odd problem with the new Apple Scanner... it appears to be
in the software. Scanning an image works very nicely, scanning at 300
dpi. Saving the image as a TIFF doc and opening it into ReadySetGo
(4.01a) works perfectly as well. However, when I save the image as
MacPaint it is blown up to match "Fatbits" image within the AppleScan
software... what was a 5" wide image becoming more like 20" wide, and,
of course, not fitting on the screen.
Opening the doc as a MacPaint image to use as a template in Adobe
Illustrator 88 (1.6) does the same thing. I would save the image as a
PICT doc and open it up in Illustrator rather than using the MacPaint
version but when I try that I get absolutely *nothing* on the screen.
Any hints on what the heck is going on, or any news of bugs in the
AppleScan program?
Thanks

David Oster is correct in principle but wrong in practice. There's a
problem with the new hooks, in that at one of the recalc times, the
lineStart array is kept in local storage. You're called to provide the
width. To do this, you need to know the start of a line (a tab at the
beginning of a line has a different width than one after other text).
All you can get at is the lineStart array in the TE record. There may
be a way around this; neither I nor several people at Apple could think
of one. There's a remote chance this was fixed by 6.0.2, but I don't
think so (I can't remember when I last tested it). I had tabs working
except for this. They did slow things down a bit, but it was only about
as bad as using styled text.

Date: 18-OCT 00:10 Programming Techniques
To avoid heap fragmentation when calling GetNewWindow or GetNewCWindow
is it best to pass a pointer for the dStorage argument in the call (I
don't have IM at home so I may have the name slightly wrong--this is the
pointer to the window record). I have been passing a 0L in my calls and
it my be better to pass a pointer to the ROM routine. If my windows are
all initialized at start-up of my program they may not fragment the heap
much I suppose so this may not be a major concern but I would like to
know if it is a major "no-no" not to pass a pointer.
I'm not doing it because sometimes I can't get it to work if I pass a
pointer to a global window record. How do you call GetNewWindow? -Doug

It really depends on your program. Nonrelocatable blocks normally get
created at the bottom of the heap, so if you create them all early,
there's no problem. If you create them dynamically, you might be
creating them in the middle of the heap and then free stuff below them,
creating an island. But if they're dynamic, you don't know how much
global space to allocate. I kind of do both.

I wrote my own version of Uriah -- and can probably still find it.
Normally, I don't have trouble with heap fragmentation. Most of my data
is kept in handles, which I hardly ever lock and then only for the
shortest possible time. My windows are all created on the heap, in Ptr
blocks. Even though they are of different sizes and are created and
destroyed frequently, they don't cause much trouble since they are small
-- only a couple of hundred bytes -- and they are the only
non-relocatable objects. I recommend that you keep your data in
(unlocked) handles and only use Ptrs for the objects that require them.

Subject: Videotaping Mac II Color Monitor
Date: 19-OCT 09:39 Macintosh Developers
In attempting to videotape a program demonstration from Apple's HiRes
Color Monitor on a Mac II (with an Ikegami camera), I found that in
contrast to videotaping from the SE there is an unacceptable visual
beating. Does anyone know of a simple scheme to sync a video camera to
the Mac II display short of a $15,000 Genlock System? Thanks. -Richard

The Macintosh II has a frame rate of about 70hz which is vastly
different from the 60hx frame rate of TV sets. You might consider trying
some ancient technology - A movie camera that uses photographic film. If
you can slow down a nominal 24 fps rate slightly you can obtain an exact
sync.

Does anyone have experience with Clearpoint memory upgrades for the Mac
or Mac II? They appear to have competitive pricing and delivery much
faster than Apple or National Semiconductor. What I donUt know is how
good their product is. I understand you canUt mix other memory products
with ClearpointUs. Can anyone help? Thanks in advance. -- Mark

Can't mix? Who said that? Memory is memory. *I* have some Clearpoint
memory mixed in with Apple memory. We have gone to Clearpoint where I
work as our memory source (not only for Macs but for Suns as well). We
haven't experienced any problems they didn't immediately fix and they
have a lifetime guarantee on their products. I would recommend them.

I use LaserStatus, which I believe came from CE Software's DiskTools
package. Works fine under 6.0.2.

Ric, does the 68030 require RAM that is faster than 120 ns? I have seen
several ads for 100 ns and 80 ns RAM. I plan to upgrade my Mac II
eventually to the 030, but need more RAM now. Also, any idea as to the
price differential?
Thanks, Ben

Ben,
I believe the Mac IIx has the same RAM timing requirements as the Mac II
- 120ns RAM is fine and faster RAM won't help. (You might want to
double-check though, to see that the IIx comes standard with 120ns
parts).
Prices usually go up steeply for speeds below 120 ns, I think.
So far, the only Mac I've seen that takes advantage of fast RAM is the
Novy- accelerated Mac SE, which lets you set the number of wait states
on the accelerator board with jumpers.

Does anyone know of any software to assist with filing 1099's with the
IRS using the Mac? The instructions the IRS sent out say that it can be
done, but it's obvious that they prefer MS-DOS. They require a 420 byte
record length for each record. I think I can do it in Word, but it is
going to be very cumbersome. Any assistance would be appreciated. By the
way, isn't there an Apple agency that helps with government interaction?
Or is it just for government sales?!
Thanks, Ben

How does SUM compare to 1st Aid? Also, what about the new PC Tools for
the Mac?
I only want to buy one of these packages, and had been expecting that
SUM was it, but am curious about the other two. Especially, I had heard
that the documentation for 1st Aid was so wonderful that using any disk
editor got better results if you had their documentation. How does
SUM's documentation stack up?
