I'm getting a Powerbook 170 and I'm looking for comments on external
video options.  I've done some research on my own, but I'd like to
get any additional information, options, and/or personal experiences
from you all.  Please E-mail me and I will post a summary of replies.

This is the information that I have gathered:

I've heard it's slightly slower than the IIsi's built-in video for most
applications.

Comments: Fast.  For all the video modes, sounds like a good deal to me.
Like Envisio, can piggyback 2MB expansion for total of 8MB system.  A
whole 1MB of VRAM for 8 bit color at 1024x768.  I'd like to know the
refresh rates at the high modes though; hopefully > 70Hz.

Please send me any info on other products, additional information on the above,
and comments from those who own the products.  Again I will post summary.

Summary: Get the newer DoubleColor SX for Apples 16" monitor or it won't work.
Organization: Lockheed Engineering (Houston, TX)
Distribution: na
Date: Wed, 15 Apr 1992 13:54:28 GMT

I just got my IIci set up with the Apple 16" monitor and it looks great.
But... I lost a weekend of computing due to the E-Machines DoubleColor card 
being incompatable with the new monitor.  To their credit though, E-machines 
traded me a new DoubleColor SX that *is* compatable overnight when they called
me back on Monday.  The older card worked great with my 13" at work, and at
$328
at Mac's Place it beats the Apple 8*24.  I was told by a sales rep at Mac's
Place that they have to sell their stock of the older cards before E-machines
will send them the new card.  SO ASK FOR A COMPATABLE CARD.  The apple 16 is
new enough that there may be a few incompatable cards by other vendors too.

I ran Speedometer on my machine at work (IIci with System 6.07) and the color
card sped up the CPU benchmarks by 28%, the FPU by 8% and the 8bit color by
18%.
However, the monochrome slowed down by 19%, the 2bit slowed down by 23% and the
4bit slowed down by 27%.  What gives? Is it a difference due to Speedometer or
the fact that the ci is transferring data to the color card rather than putting
it in RAM for the onboard display? 
I didn't have time to try it out with some real-world tests. :(

This is just not true. The Quadra 700 is advertised in the UK as being
expandable
to 68Mb.

The only problem is that you have limited physical room in which to put the
16Mb
SIMMS which at present are typically too large to go in the space available
under
the disk drive.

However, I have seen some adverts for 16Mb SIMMS which are supposed to be
Quadra
700 compatible. Check out the backs of various Mac magazines.

Reply-To: jlw7@midway.uchicago.edu
Organization: University of Chicago Computing Organizations
Date: Fri, 17 Apr 1992 18:35:06 GMT

After checking ito the Mobius upgrade, I found that the SE/30 upgrade was,
overall, superior.  Even though the processor is slower, it includes a
math coprocessor at no extra charge.  With the Mobius upgrade, you have to 
spend $200 extra (I believe) to get the 68030 chip, rather than the 68EC030.
The difference is the 68030 has a built-in PMMU, allowing Virtual Memory and
(I may be wrong on this) more than 4 megs RAM.  The SCSI throughput is faster
on an SE/30 than an SE with a Mobius upgrade, since the upgrade doesn't improve
the SE's SCSI performance.  The fact that the SE/30 has new(er) ROMs helps, as 
well.  If you want, you could hook up a color monitor (with a card) to an 
SE/30.  You are stuck with Black and White when you go Mobius.  In order to use
things like VM on the Mobius, you need to use the program (init?) Virtual,
which is inclued if you get the PMMU version of the upgrade.  However, 
additional software is always something that can go wrong later.  You don't
have to worry about that on an SE/30.  For what it's worth, the SE/30 includes
sterio sound output, while the SE only has mono.

The big differeence I've found, however, is price.  Being in the middle of 
choosing between the Mobius or SE/30 upgrade, this was the biggest consider-
ation for me.  I found a used full page monitor on the market for $300, which
included an SE/30 card.  Adding this to the $850 it would cost me to upgrade
my SE FDHD to an SE/30 (including labor) brought my entire expenses to $1150,
and I ended up with a "true" mac, rather than an an "accellerated" mac, and
paid $200 less.  If you include the "extras" you'd have to get with the Mobius
to equal the "extras" on the SE/30, the margin increases.  However, there is
a place for the Mobius.  If you need processor speed above all else, the pro-
cessor in the Mobius is 1/3 faster than the processor in the SE/30.  If you
need a faster machine in general, or don't have a SuperDrive in your SE al-
ready, I recommend the SE/30 upgrade.

I would strongly recommend getting your keyboard from Apple.  I am
*VERY* unsatisfied with the third party extended keyboard that I have
at home, especially in comparison with the one that I have at work.

Consider this: Your keyboard is probably the one part of your computer
that you will use the most, the most critical part on the data entry
path.  A Bad keyboard will lead to frustration, more medical problems,
etc.  Is it really worth saving the $60 on your keyboard?

If I was to buy one over again, I would NOT buy it from a third party.
In fact, I would be glad to sell you mine, so I can get an Apple
keyboard  :-).  (In reality, I will probably buy a new one fairly
soon anyway)

Summary: (Q) How do PowerCache cards work?
Keywords: daystar,powercache


I am curious as to how Daystar PowerCache cards work.

Question 1: 
Is PowerCache 50 MHz based on a 68030 clocked at 50 MHz? (I
thought, for 68030, 40 MHz, that is, IIfx CPU, was the fastest among the
existing ones. Does a 50 MHz one by Motoroloa actually exist?)  Or does the
card simply consist of a large cache clocked at high frequency?

Question 2: If each of these cache cards does have a separate CPU, then does
it, when installed, simply block the original CPU on your Mac or does it
"share" the load with the original? If it indeed put the original CPU out of
job anyway, then wouldn't it be cheaper to by Mac IIsi or IIci and install
the Daystar 50 MHz PowerCache rather than buying a Quadra (unless you really
need the extra features of a Quadra)?

Last Question: Does the 68882 FPU installable on these cache card have to
operate at the same frequency? For example, can a 20 MHz 68882 (a slower FPU)
used with a 50 MHz PowerCache?


Your enlightening info will be greatly appreciated.

Why do you assume this?  The cost savings in keeping the package
size/gate count down by designing with 16-bit buses still dominates
the design criteria.  That is, using 16-bit datapaths is just as
compelling with either the '020 or '030.  If they started with the
'030, they would've faced the same cost issues.

Further, the cost of an '030 vs the '020 at the time of the initial LC
design was probably too high.  My guess is they always intended to do
an LC II by substituting the '030 when the price was right.

Also, I don't think it was a "bean counter" (ie, accountant) that made
this decision.  They needed a machine at a certain price/performance
point, and this is how engineering decided to fill that point.  Even
an engineering student can make a gross profit calculation: revenue -
cost-of-goods-sold. :-)

Strictly speaking no one can do 24-bit video from video, there's just not the
bandwidth there - the chipsets most people use produce 16-bit (actually less
than 16-bits) of digital data stored in YUV format, when this is converted
to RGB you end up with whatever your framestore supports (ie 8/16/24 bits)
but final resolution (ie the number of different colors) is dependant on the
source less whatever might be lost during the compression process.

Converting for display does have an effect on the result, 8-bit framestores
need to be dithered which takes much more time and doesn't look as good,
16-bit framestores take more time to put the RGB components together than
24-bit ones.

BTW the PAL signals used in most countries other than the US tend to have about
20% more bandwidth than the NTSC used in the US - the results are really
noticable with much better colors than here - (something to learn for HDTV -
next time learn from someone else's mistakes :-)

Video compressors (also including the 'Spigot one) depend on knowing the
resolution of what they are compressing and get some of their compression
performance by throwing away data they know has too high a bandwidth for
a video signal (after all there's no point in compressing noise). That's
also why it makes sense to have an animation compressor (animation tends
to have high contrast features where color/intensity changes suddenly).

Nope!  You can only network them.  I asked about this when I went to the
rollout and they explained that the 140 and 170 were farther down the
development pipeline than the 100 when they came up with the idea.
Hence, the 100 was the only one that could be re-engineered.  We (the
crowd) made it very clear that all future PB's should have this feature.
The fellows doing the demos were the head engineers on the project and
said that they would do their best to do so in the future...

  I have seen the inside of my PB140 (the drive died).  Only space for the

There are other choices, 60-100MB, in the proper size media.  Check magazines

Check which compressor you are using to create the movie file.  The
"video" compressor, normally the one you'd want to use, doesn't do
24 bit color.  The best it can do is 16 bit color.

Try another compressor, such as the animation compressor (it's not
as good with photorealistic images, but it does support 24 bit color)
or even none.

I agree that the still image capture is excellent.  I hooked my spigot
to my Sony CCD-TR81 (it has more scan lines than most camcorders)
and got better results than I've gotten from some color scanners.

The Spigot is probably worth it just for still image capture!
