Hi Everyone

Well the A4000 is a last here, 25mhz 68040 processor
2Mb of chip RAM, 4Mb of fast RAM and the AGA chip set.

But .. does anyone know how fast this machine is I
have  a  quote  here  from a  UK  magazine " Amiga 
Computing" that says at the unveiling of the A4000
at  the  recent world of Commodore Amiga  show  in
Pasadena CA a Commodore  employee demonstrated the
following. A HAM8 Raytraced animation that updated
at 60 frames per second in  640x400 resolution. He
also stated  that the A4000 could handle 60 frames
per second animation  in any resolution  and color
depth.

From  what I have heard a lot of people or  saying
that the  A4000 is slow  at animation play  backs,
but  this  does not  seem to be the case here,  or
are  Commodore  using low  delta  frames  to  show
off more speed.

Gary ..

PS Does low delta  mean  not  much change  between 
   frames or is that high delta?

Keywords: DSUB, Zorro-II

I'm sure this has been covered many times over during the life of the Amiga, but
I'll ask anyway (since I've never seen an answer).  

Does anyone know of a supplier of the 23 pin DSUB connectors (or cables) that C=
loves to use for everything from video to FD interface?  After owning my
venerable A500 for 5-6 years now I finally am forced to relocate my external FD
and need to extend the pitifully short cable.

Also any info on suppliers of A500 expansion slot card edge connector would be
appreciated.

I have to disagree with you on this.  I'm sitting here looking at several
types of bi-directional buffers right now, and none of them are all that
expensive -- and that's retail.  At the OEM level they would be very cheap.
I'm talking 2.00 US for off the shelf, two to a pack.  Compared to around
20.00 US for a CIA, that's not too bad.  Not to mention that it is available
at most electrinic supply houses, while the CIA is limited in availability.

Interesting... if the serial port is uni-directional, how do we manage to
send/receive data via a modem?  Still, I daresay that RS232 buffers are a
fair sight cheaper than a single CIA.

*sigh* Look back a couple of hundred messages, and I think you'll find my
brief explanation of this. I definitely think this needs documenting in full.
In fact, I'm going to do just that when I wake up tomorrow morning. :-)  (Hi
again Ralph. :-) )

>If latter, which?

Very, very, very briefly:

- The VXL is the only 68000-socket accelerator that I know that supports
  DMA-able 32-bit RAM.

- Most "real" A2000 CPU slot accelerators support DMA-able 32-bit RAM, if only
  because a lot of them have SCSI interfaces onboard. ;-)  (Mine doesn't, BTW.)

- The non-DMA-32-bit-RAM problem is no longer a serious cause for worry ever
  since I wrote DMAfix. :-)  If you don't find DMAfix fast enough, register it,
  and it may go even faster. If you find it too much of a hack, buy an 
  accelerator from SSL, and get the "commercial" version. (Plug, plug.) If you
  don't like the idea of a hack at all, buy a GVP Series II. (Plug, plug.) If
  you don't like the idea of your HD slowing down ~20%, buy an A3000. <grin>

>I don't really need all that kick though, a 68020 and 68881 would be enough.

  As the subject line says, we are looking for a long persistence

a flicker-fixer board is not an option.

Do these things still exist?  Does anybody still make them?
Any info, comments or calls from salespeople are welcome.

My 2.04 kit instructions are at home, but I believe you will have to
upgrade the A2620 ROMs.  Not so with the A2090A.  I'm fairly sure
there have never been any 2090A ROM upgrades.  There _have_ been
several for the A2091 controller.

>Does "not recommended" mean:
>  (1)  the A2090A will not work with 2.xx?

Works ok on mine, I can autoboot a FFS DH0: partition.  You can 
even use it with Amiga Unix 2.1, if you like. ;-)

Nah..... ;-)

>  (3)  all of the above?

The primary thing the 2090A lacks is Rigid Disk Block (RDB) support, 
and it is not the fastest controller around nowadays.  Not that any
ST-506 drive is, compared to typical SCSI drives.  But it is a lot 
faster than floppies..

   The Zorro-III spec specifies Zorro-II operation.  Only incomplete
   Zorro-III bus implementations would not have Zorro-II.

   The A4000 has a full Zorro-III bus implementation.  Thus, it includes
   the Zorro-II mode.

   Note that Zorro-III is the only way to get high-performance cards
   on the bus.  Zorro-II is, at this point in time, rather slow.  (Back when
   it came out it was very nice...)  Basically, Zorro-II is about the
   same in performance as the old IBM-PC/AT bus (called ISA)

   |      /// Michael Sinz  -  Senior Amiga Systems Engineer              |


Actually what I meant was the Zorro III bus modes included in the spec as
published in the hardware reference manual but never implemented on the
3000.  (Quick Interupts, Multiple Read)  Thanks for the answer though.

As Skip said, the problem with Marc is that he is negative.  Some of
his negative posts have been 'on the mark' but the vast majority
are mean, spiteful, lies, or twisted logic full of half truths.

Which would not put him in a special category by himself if he posted
at the normal rate of 1 or 2 idiocies per month.  His real problem is
that he posts them in spurts of idiocies per day.  Then he repeats them.
Often.  Despite flames and hate mail and logical corrections.

So, give it a month or two and see if you feel Marc is treated harshly.

Is this really such a big deal?  I've yet to see a multiscan monitor which
has no distortion in the extremes of full overscan.  While overscan may be
neat for NTSC and PAL, it is not so useful on multiscan/VGA/SVGA monitors
and is not really needed.

Without doubt. It's great for the low-end machines to have a cheap and pretty 
fast IDE/AT interface, which doesn't add much to the price of the machine.

This may seem like a silly question but I am trying to work out what
is the best thing to do with a B2000 hard disk when I move the machine.
I have had the Amiga2000 for about 5 years its on of those with the
PC XT-Bridgeboard and the hard drive with the Janus handler (JH0:).

I have been told that on one of the system 5 1/4" disks there is a 
program called shipdisk, does anyone know about this or what you
do with it. Does anyone know out there if the hard drive  (Western
Digital) will be auto parking. Finally does anyone know of anything
else that can be used or is SHIPDISK the best bet.

If the drive is not parked what damage can be done! Please note that
many all the drives produced now are auto parking and there is no
problem in maving the machines around, without first parking.

Thank you for any help. Gary .

   No, it is not correct.  The "promotion" feature is software-only.  If a
program (such as an old, unsupported utility or game) insists on opening an
interlaced screen, the screen will be opened as interlaced and there will be
nothing you will be able to do about it.

Anything that can go on the motherboard could certainly be supported on a
card.  The main problem right now with Amiga graphics on a Zorro card is that
graphics library would need some work, though not all the way to RTG.  Also,
programs that bypass the OS wouldn't work on these, but that's something
everyone will need to get used to in the future anyway -- use the OS or die.
I'm only speaking to what's technically possible, if you're concerned with
what C= will or won't actually build, you need to talk to someone else.

It's part of the support system for different Alice chips.  The Alice part was
two years in the making.  Over that time, we in the systems group defined 2M
and 8M pinouts, then later a pinout with an extra VCC pin, then finally a 
pinout with a VBB bypass outlet.  Support of these latter two options is the
concern of both Alice jumpers, and nothing for anyone else to worry about.

As explained here before, those are jumpers that can be read through the Lisa
chip.  The first two, which you don't see, are used by the OS to sense the
type of bus that this particular AA system implements (in this case, Fast 
32-bit).  Functions have not been assigned to the remaining six bits.

In retrospect, that would have been a good idea.

Look folks, if the Alice chip supported 4MB or 8MB of RAM, it would do that
right out of the box.  Honest.  There's no reason to change around any PCB
jumpers, it's only going to get you in trouble.  NEVER EVER mess with a PCB
jumper you don't understand, even if it's labelled "SEX AND FREE BEER".

1MBx9's should work fine, make sure they are at least 100ns (I don't think  
they make them slower any more).  

You can add up to 4 Megs using the 1x8's or 1x9's, but if you want to go  
to 8 megs, you have to use 4megx8's.
