Yep, the real goal of the the AGA chipset was to get the standard Amiga
display resolution (640*480) up to 8-bit planes, 60 Hz non-interlaced,
which it does.  This is VGA territory, the WOC presentation made it
pretty clear that we were working on better stuff for the future.

The software folks implemented some of the higher resolution modes as
interlaced modes so that you can use them if the interlace doesn't
bother you.  Human factors has it that small increments of refresh
rate from 24 Hz up yield fairly large perceptual reductions of
flicker depending on lighting level and personal senstivity.

A 800*600 36/72 Hz display is also a pretty good target for a super-
deinterlacer, should someone chose to build one.

I don't remember right off, for the really fast stuff you currently
need either a custom fixed frequency monitor or one of the more
expensive 30Khz and up multi-sync monitors.  I had a nice chart that
cames with WD based SVGA cards, what a mess of wierd scan rates,
pixel clocks and interlace modes, thoush a lot were just for backwards
compatibility with older SVGA implementations.

Yep, works good in the same modes that the one built into the A3000 does.
It's the same chip (C= version), building it in to the A3000 was an
afterthought.

Just purchase a "Y" cable.  I just did this for a customer at it works
fine.  135watts is quite a bit, as long as you dont have all the slots

Actually, the way I would put it is that the average Commodore customer
should be able to view the Commodore that he buys his computer from as
one company, subject to the understanding that the deal he gets in his
country may not be exactly what is offered in other countries.

However, if you want to have the opportunity to talk with the individuals
who work for Commodore and have some responsibility for the design of
the hardware and software (rather exceptional, eh?), then you have to
accept the responsibility of understanding that those individuals do not
work in any idealized monolithic corporation.

In fact, we - the engineering and support folks are responsible to the
international organization, while the CBM that you - the US customer
deal with is just one of many "national sales companies".  Luckily
there is communication between the two and an engineering department
located in West Chester always has problems in viewing things from an
US rather than truly international point of view...

It could be coming from the A4000's manual where it shows you how to
upgrade your 68EC040 processor to a full 68040.  Of course, the machine
ships with a full 68040...  Does this hint at different models...?

Subject: Multi-Serial ports on an A500
Date: 16 Oct 92 12:52:27 EST
Organization: Western Michigan University

I have an Amiga 500 and I need extra serial ports.

At least one extra serial port.  So I have two questions.

#1 - Can I make the parallel port act like a serial port (or like more than
     one serial ports.. who knows..)

     If so, where can I get such an adapter, or what would the wire
     configurations be for me to build such an adapter?

#2 - Expansion Systems sells their A500 hard drive controller case
     seperately.  I'm not sure, but the port that it converts to 
     looks like a regular A2000 port.  If this is true, then could
     I build a little side item that would take an A2232 multi-serial
     port card (with a little hacking of course.. I'd HAVE to have a
     pass-thru somehow.

     If this is possible, would someone be willing to mail me some
     instructions and stuff?

Thanks!

Is this to say that, in general, AGA has a four times increase in
bandwidth capable in all screen modes?  Is a 320X400X24 screen possible?
(320X400X6 is a normal Amiga mode, so times four is 320X400X24, right?)
Is this one of those modes that hasn't been explored yet in the AGA
chipset, or is this just a wild fantasy???

I do not have a low of time to write this, but I will give you some of the

then the education individual prices.  This is not to say that all dealers
are like this.  However, institution prices are significantly lower.

It should work well, both with or without a flicker fixer.  The only
problem with some of the NEC multi-sync monitors is that they do not
handle interlaced displays, which would make them a poor choice for
interlaced NTSC multi-media displays.  This is obviously not a major
issue if you plan to use it in conjuction with a de-interlacer.

 I agree. Another noticable problem is the fringing in HAM modes. These people

Sure it does. The only difference is that upgrading the CPU on an A4000
leaves you with a spare card while the A3000 leaves its original CPU
conveniently on the motherboard. In both cases you can't use them.

That's reasonable. But folks with an A500/A600/A1000/A2000 or no Amiga
will probably prefer the A4000.

candidate!  It is painfully obvious.  It is a couple hours before the debate,
and predict Perot will chop em up into little bits and serve them for dinner...
as he did last time (if not more).  Clinton reminds me of my greeting program
that tells me what to do for the day every time I boot up.  He is pure 
politician through and through.  And I will lay a $100 wager with anybody here
that if Clinton is elected (likely unfortunatly) he will tax the people and soak
the people (non-upper class) as much as Perot wants to - while at the same time
not even touching the deficit (whereas Perot WILL).                      
    Is there actually an intelligent person out there who firmly believes 
Clinton will cut the deficit?  He never even mentioned it until Perot forced
the issue on the table.  A vote for anyone other than Perot is a vote for
deficit spending, which should be illegal.  [had to be said]

The card will work, but only knows about the 12 most significant bits
of the digital colors.  Using it would "save bandwidth", but so does
running a 6 or 7 bitplane workbench, which is a "free" selection on the
preference menu.  The display enhancer doesn't know whether you are
running 4 or 8 bitplanes, all it sees is the resulting 12 bit digital
RGB values - (24 bits availabile in the A4000 video slot).
