Right now there isn't much in it and it's just an unorganised collection of
some  articles  taken from some newsgroups.  I haven't even typed in all my
experience  with  the  A3640  .   Also some of the information given in one
Article is contradicted in the next one.  This needs to be corrected and
clarified.
 
Let me know your likes an dislikes.  Any input will be greatly appreciated!

1.3. What is an A3640?
======================
 
The  A3640  is  a daughterboard that carries a 25Mhz 68040 CPU and comes as
standard  equipment  with  a  A4000 '040.  The board not only fits into the
FAST-Slot  of  an  A4000 but also in the one that the A3000 comes with.  It
can  therefore  be  used as an accelerator for an A4000 '030 (replacing the
daughterboard  with  the  68030  CPU) or an A3000 (putting the board in the
empty FAST-Slot).
 
-HW
 
2. Hints.
=========
 
2.1. How to prevent your A3000 from overheating.
================================================
 
Unfortunately  the  68040  gets  somewhat  hotter  that a 68030.  Even more
unfortunately  some  of  the chips in the A3000 don't like heat so much.  I
measured 35 deg Celsius airtemperature just outside the power-suply fan and
45 deg Celsius just beside the 68040.
 
Radiating  heat:   The  A3640 comes with a mounted aluminium heat radiator.
Aparently  there  are two version.  One (the early version) that is to high
to  fit  in the A3000 and a flatter one that fits also in the A3000.  It is
not  necessary  to  cut  a hole in the drive-mounting frame to make fit the
higher  radiator.   Just  replace  the radiator with a smaller one.  With a
little luck (also called "searching") you'll find one that can even be held
in  place  with  the same clamp that held the original radiator.  You might
also  want  to  put  some  heat-conducting  paste between the 68040 and the
radiator to have an optimum flow of heat between them.
 
Airflow:   Have a look at the back of your A3000.  You'll notice the fan of
the  power-suply  on one side and a couple of small holes one the far other
side.  The air is sucked in through the small holes beside the back-planes,
passes the expansion-cards, gets sucked through the gap that is between the
slot-daughterboard  and the front-panel (see schematics below), and finally
gets blown out by the big fan of the power-suply.
 
There are two ways to enhance air-flow:
 
1.  Get a "CPU-Cooler" with fan.  Make sure the fan can be removed from the
aluminium  cooling cap.  Remove the fan from the cap an place it in the gap
that  is between the slot-daufhterboard and the front-panel.  Use some glue
or  tape  to  fix it there.  make shure it blows the air to the right side.
Connect  it  to  a free power-cord from the power-suply.  You might want to
remove one alle unused back-planes to increase air-flow.
 
2.   Do  the same as describend in 1.  but remove the back-planes and place
the fan at the BBB location.  Place it so the air is blown into the case.

Hi Jaeson, you wrote a message dated 18-1-95
about { A3000 + A3640 } saying:
 
 jep> Besides the necessary drive mount modifications, what else is necessary
 jep> to use an A3640 with an A3000.  Are there jumpers to change?  
 
Some quotes from Dave Haynie:
 
 1) A Rev 3.1 or later A3640. Prior versions can fail with a DMA
   conflict (they let the CPU and DMA device onto the '030 bus at
   the same time).
 
 2) One of: later-than-2.04 OS in ROM, RAMSEY Rev G, or at least
   one page-mode DRAM in bank 0 of your Fast RAM array. There's a
   bug in the original RAMSEY that fails when page-detect mode is
   set up. OS 2.04 enables page-detect mode when you have static
   column memories and an '040.
 
 3) You may need a Rev D DMAC, which implies a Rev G RAMSEY anyway
   (they are paired; you can't use old DMACs with new RAMSEYs or
   vice-versa). Early DMACs, especially the Rev A, were very heat
   sensitive. The reason C= doesn't recommend the A3640 for the
   A3000 is that the '040 runs hot, intentionally. Up to 115C Tj
   is just fine. We didn't know this when the A3000 casework was
   designed, most chips only go up to 70C.
 
>From that you may gather that it may be adviseable to put an extra fan
inside to blow more air past the 3640.  Also you need to change some
motherboard jumpers:  J100 (3-4), J102 (1-2), and leave J104 (1-2).  
 
You should also look at upgrading your Buster to -11, and your WD33C93A SCSI
controller chip to 00-08 or equivalent (AMD make the same chip).

Another $0.02 into A3640 thread: I finally made this beast working
into my A3000/16, after spending several days trying whatever was
suggested.
 
What to do:
 
- Install 3.1 ROMS (40.68), first chip into U181, second one in U180, whether
  you have ROM tower (motherboards versions 7.x) or not.
- Buster does not need to be upgraded (I have rev 7).
- Change jumpers J100 to 3-4, J102 to 1-2 (an earlier post said not to
  move this one, well here I'm speaking about an A3000/16Mhz, motherboard
  version 7.0), and finally move jumper J104 to 1-2. These are for clock
handling.
- Move jumper JP851 (RAM controller speed) to 2-3 (from 16 to 25Mzh).
- Remove heatsink from 68040 processor and file it up to 1/3 height, so that
  you'll be able to keep it, otherwyse heatsink is too big to fit under
  drive bay.
- Optionnaly install a very small fan between A3000 daughter board and
  front cover, to cool 68040 a little bit more (I've made a burning test
  for 2 hours without Fan, without any problems, but I just prefer to
  be 100% sure).
- Install A3640 board (no jumper changes on this one).
 
Here you are.

Subject: Re: A3640->A3000 Desktop FAQ? OR Tips?
[Problems with A3640 in A3000]
 
I`m using an A3000T-040 with this board...
 
I had to upgrade the CPU to Dave`s? Rev3.2 (3 PALs),
new Buster-11, Ramsey-7, DMAC-04.
 
You won`t be able to upgrade Ramsey,DMAC (because DMAC is not available).
You`re using a very old A3000. Try to upgrade to the `normal`
A3000 chipset (Dmac-02, Ramsey-04), a hardkicked OS,
and fix CPU board to Rev3.2.
 
Ask for JEDEC-Code of the PALs in this group, if you`re able to
do them on your own.
Ask for old A3000 Chips, too.

Hi Jon,
 
-> Just purchased an A3640 (040/25) card and having problems
-> installing/getting it to work in my A3000. Any assistance appreciated
-> with how to get it going. My system is an A3000/25 with 18 megs RAM.
-> After installing the board, the system jusst sits - no bootup at all.
-> Have installed set040 and it make no difference. HELP!!! Are their
-> some jumper settings that need to be changed?
 
Don't panic.
 
J100 - change from 1-2 to 3-4.
J102 - change from 2-3 to 1-2.
 
Now officially you should not change J102 - you should change J104, BUT
it will lock up after 30-45 seconds that way - SO....change J102.
 
 
If you already don't have it - get the latest 68040.library (37.30) and
the latest setpatch (40.16).
 
Besides J100 and J102 you should also know that if you have KS 37.175 in
ROM you will need at least 1 (one) PAGE mode ZIP chip in Bank 0. If you
have KS 40.68 or 40.70 (OS 3.1) all Static Column are OK.
 
If you have "kick" ROMs that load the KS image from HD - forget it - the
A3640 does NOT work with this ROM set.
 
Later, Terry

Very possible if you either have an LC040, an EC040, or an improper
'040 setup.

That's correct.

Leaving it alone is your best bet. The '040 doesn't really generate
external coprocessor cycles, though, so it's probably not going to
matter which setting it's on.
 
>You may have a 68LC040, which doesn't have a functional FPU.
 
That's one possibility. However, it could just as easily be your
software setup. Part of the '040s FPU standard is implemented in
software. That software is 68040.library, which is loaded by the
appropriate SetPatch (eg, don't use an ancient one, but the proper
up-to-date release is the right one, first thing in the
Startup-Sequence). If the 68040 library is installed, things like CPU
will list the '040 as having an FPU, otherwise it won't. 
 
DO NOT RUN THE '040 WITHOUT 68040.LIBRARY!!! The ROM-based Amiga OS
does not fully support the '040, and you will run into trouble without
this library. For example, the '040 caches won't be set up properly.

I had a similiar problem when I put >12 meg fast ram in my A3000T.  I noticed
that with only 12 meg of memory it worked ok, but with 16 meg memory I had to
put in an Apple-style SCSI terminator for it to work.  Another way it worked
was to put a pagemode zip in the U850 (first one) socket.  In my case the
computer come up with the insert workbench disk animation.  For Gilles's
problem, did you make sure that you set all the jumpers correctly?  I believe
that the J100, J102 (or J104) need to be set correctly for "external".
