Summary: They just don't like each other.

I recently installed the 1 meg Agnus, and shielded of the necessary pin
to make it register as PAL.  I do not have the ECS Denise.  I run KS
2.04 on an Amiga 500.  

However, there seems to be some conflict with Mode_Names.info in the
WBStartup draw.  The Workbench freezes up.  If I execute (read: double
click) it later, the WB freezes up again.

Sigh.  Any help would be VASTLY appreciated.  E-Mail or followup.

Many thanks.

Hi world,

I just got a A3640-Board (the 68040 for A3000T and A4000) for testing.

There is not enought room in the A3000-Desktop, because the heat sink
is to big. :-(  But I love Computers without a case. :-)

I plug it in my A3000, switch power on, and nothing happens....(Black sreen)

Must I remove the 68030-Processor or must I change a jumper ????????

Who can help ? :-) (Dave Haynie) :-)

Achim

PS: It is an A3000 Rev. 9.0 with 37.175-ROMs, 16MB Fast and 2MB Chip

Just a thought.. 

But why wouldn't the big C= sell the 3000 tower case by itself so
3000 owners could 'upgrade' (if this is considered an upgrade!)
THere are Bomac towers in the US for the 2000 and I believe Golem
sells a tower for the 2000 in Europe, so why not fill the void
and market these babies!!!

If this is wasting bandwidth....

	At the moment I have a PP&S `040 board and was intending to upgrade to
a 33Mhz Zeus, then the A4000 turns up...
	What do all you gurus suggest - Should I wait for the A4000 or go for
the Zeus??? What ARE the real A4000 specs?? I certainly can`t decide
until I find out what the options are. Upgrading to a Zeus will cost me
$1400 trading in my current board. How much will it cost to get an A4000?

	Any info to help me decide would be greatly appreciated. Please email me.

The answer to your problems may lie in either your memory
configuration and/or your firmware revision on the 2091.
The 2091 needs revision 6.6 or greater chips (PALS I believe)
to work with extended RAM.  If any of your RAM on the accelerator
is set as EXTENDED, change it to autoconfig and try again. ALso,
the GVP board should recognize and use the drive formatted on the
2091 without a problem.  Try just connecting both drives on the
GVP board and forget about the 2091.

Bzzzt...  Actually, it depends upon the definition of MAX.  The data
books specify the maximum *guaranteed* clock speed for every single
processor.  What you are referring to would be called the *typical*
clock speed of the part.  That number is not often specified for 
parameters like this, because very few commercial products could
work properly if a particular part did not work at the typical
speed.  Typical numbers are much more useful for parameters such
as supply current.  For example, if I had 20 ICs on a board with a 
typical supply current of 10mA and a maximum of 40mA each, statistically
speaking I would never see 800mA being drawn by the board.  I would
tend to see about 200mA.  I could then consider using a power supply
that was rated for continuous 400mA, or thereabouts.

So, to rephrase Michael: Read the value printed on the chip (for the
maximum guaranteed speed), and ask people what they *typically* have
overdriven the part to....

In any event, the Amiga with A2065/AS225 interoperates nicely with a Sun file

As far as I know, it won't work.  I bought my GVP Combo six month ago, but
I didn't have a SCSI HD yet, so I thought I could rely upon my good old
A2091.  But no.  When the Combo card is on the A2091 doesn't work.  It's not
the GVP controller thas conflicts, it's the 030.  Using a GVP controller
with a 2091 works fine though.

I think I've testet almost every possible way, but I certainly can't get it
to work.  In the end I inquired at my local dealer, and he simply stated
that they were not compatible.

So I backuped my 2091, sold it, and went to diskswapping.  Still saving for
that HD!

Sorry, I haven't any idea [ though I have seen the two items at the local
Amiga dealer's (HT Electronics, Sunnyvale CA) ].

My ``impression'' is the A2065 Ethernet card is somewheres between $200 and
$400, and that the A225 software is somewheres between $100 and $200.

Suggest you check the ads in one of the Amiga-related magazines and/or ask
your local Amiga dealer.

There have been frequent problems with cold solder joints in the
power supply of these monitors.  This can easily be repaired by
someone *who knows what they are doing*.  If you don't know, don't
open up the monitor.  This often helps prevent electrocutions =:-|

I wonder what you mean by the picture "vanishing".  Does the screen
go black or is there still raster?  Turn up the brightness and contrast
when this happens and see if you can get at least a grey screen.  If
you can, it's probably not the power supply.

And it looks like they are being phased out. I saw them priced at

haven't the deskspace for another monitor unfortunately. :-)

My SyQuest 44 Meg drive worked fine on my A2500 after upgrading the
A2091 to Version 6.6 ROMS.

I also had to upgrade the SyQuest ROMs. SyQuest was very helpful.
Even though I had bought a used drive, they mailed the ROMs to me when
I phoned them to ask about my problem.

The A2091 ROM upgrade was only necessary in order to write from
one drive to the other on the A2091 SCSI bus.

	If you're looking for a real speed increase, such as faster ray

	I owned a 22 MHZ combo card and it was about twice as fast as my
	68000.  A friend of mine had a 030 @50mhz and it only made frames
	2 minutes faster.  A small frame with 2 brush maps:

	68000		25 minutes
	22mhz		14 minutes
	50mhz		12 minutes

	So I guess my point would be, Do you think it's worth it?

Yes, this was the basic reason why it was put in there anyways: To get a non-
lace output without resorting to a flicker-fixer solution.

Just connect your VGA montitor to the 23-pin video DSUB (you need a converter 
to the 15-pin high-density DSUB the VGA monitor probably uses). If you have 
two monitors, it would be a good idea to connect both in parallel, since the 
VGA monitor will not be able to display any 15Khz resultions.

That's funny my Sparc 2's GUI is faster and more responsive than my 25MHz
A3000's. But then again a I use the 2.04 WB on a 710x460 screen @3 bit
planes on the amiga. I'm really getting tired of people comparing Apples
and oranges and then somehow using that as evidence the orange is
better. Especially with regards to how fast the Amiga's GUI is.

As CPU power increases, ideally your custom coprocessors power
and speed should scale proportionately, otherwise at some point the
copro's end up being slower than just letting the main CPU do it (in
addition to processing program instructions).

The 3000 still wins most of the time by having custom copro's but since
the copro's really have not been upgraded it starts to become more
apparent that on systems faster than the 030-based boxes we need a
faster chip set. I haven't seen enough hard info on AGA to tell if the
custom chips are a win for the 4000's GUI. I suspect they probably are,
but even if they aren't there is probably some way to wrest more display
processing duties from the chips and give it to the CPU. (A la CPUBLIT
for the 3000 but with more functions taken over.)

It would be both sad and amusing to watch my A3000 try to push around an
8 bitplane workbench at the resolutions my Sparc does (assuming it
wouldn't run out of chip mem :^).

I likewise have this card...but mine has the Autoboot daughterboard on it
...I on the otherhand do NOT have software for the board...I would be more
than willing to part with this board for about $35 +shipping.....otherwise
I'd really like to get a copy of the software.

Don't forget that SuperHires also offers Overscan, up to 1448 pixles wide 
display. Would give you 482 pixels in this mode...

> 2. 15-bit true colour in 640 x 512 (PAL)

...and 724 pixels in that mode. Very interesting, indeed!

This bit can be used as a brightness switch, giving you EHB with ever more 
colour shades, I think.
