Chad,
I recently installed an A3640 in my 3000 desktop. Armed with no
documentation, I set all 3 jumpers that looked clock related to
the setting marked "EXT". I had the same problem you are describing.
The solution was to set the jumper for the board clock back to internal.
I think it was labeled "BRD CLK".
I don't know about a 3000T, but on a 3000 desktop it's a real pain to
play with the jumpers!

I just posted the complete set of jumpers as I have them set on my A3000T
with the A3640.
Look for a message thread posted in this group as
"A3000T hates Buster 11: Dave Haynie know why? "
I have mine working fine with a rev 7 Buster but the rev11 kills the
system worse than yours.....but it sounds like the same symptoms....

The space where the 74F08 is often EMPTY so you have to add one yourself.
The jumper below J102 seems to be without any mumber, I guess it is J101
J 107 and 105 should be without jumpers, J106 has originally no jumper but
it is needed.
And you MUST have atleast Kickstart 2.04 in ROM (not softbooted) and the
first ZIPP should be PAGEMODE! I have heard that if you have Kickstart 3.1
you can have a Static Column ZIPP in the first socket. but I haven't tried
it.
After doing this you should have a working 3640 in your Amiga 3000Tower.
I'm using a Rev. 3.1 3640 in my Tower, it is equipped with the old Ramsey
and Dmac but Rev. 11 buster (should not be needed here)

There are more combinations for CPU`s which are f.e. able to switch back to 030
...I would say...very cool design!
74F08 is normaly NOT placed in A3000T...these settigs don`t work without it!
Buster? DMAC is a problem (overheating...FALSE timing).

Hi!
This info helped me a lot, thanks for posting it a while back...
A couple things here.....The jumper you have marked as J102 is actually
J104, and the unmarked one is J102 - I found the designation for J104
very nearly hidden under another component above and to the right of the
jumper as you look at it in this plan...
Someone else said the jumpers 105 and 107 should be jumpered to pins 1-2
per the schematics to make 74F08 work - I am waiting to hear what the
official use of these jumpers is......
I have mine set exactly as you show here.
I had/have everything working pretty well in my Tower now with rev 7
Buster and DMAC 02 Ramsey 04. I got a rev 11 Buster and the stupid thing
won't work at all with it installed, won't warm boot and will only cold
boot from floppy disk with reports of harddisk not being validated. I
tried two rev 11's and ended putting the rev 7 back in....any idea what
else might be wrong?

That is the suggestion most people gave me when I installed my A3640 a year
ago, but I found that that setting gave me a very unstable system. I had to
upgrade to SDMAC-04 which gave me other problems. However, I have now found out
that Reversing BRD CLK and CPU CLK, i.e setting BRD=EXT and CPU=INT, proved to
be the only solution (so far) to my problem with getting my system (m/b rev
9/03, SDMAC-02 & RAMSEY-04) to run the A3640 (rev 3.0) saftely. It works great.
So I guess the rule is, if it doesn't work one way, try the other...

Indeed. Hint: Unscrew the power supply from the drive bay so can you can supply
the mainboard with power without the drive bay mounted on top of the jumper
area. The floppy cable may well be long enough to allow it to be connected
without removing the drives from the drive bay. This way, you can fiddle with
the jumpers without having to put the drive bay back and forth. It's really
worth the trouble, because you can try different settings much easier.

I am running a Rev 3.1 A3640. I don't know what the difference is
between 3.0 and 3.1, but maybe that is part of your problem?

Well, I have had some very detailed explanations and suggestions sent to me by
Dave Haynie (thanks Dave!). Using a rev 3.0 board in an A3000 is definatly not
a good idea, although the problem with DMA devices (such as the on-board SCSI
host adaptor in the A3000!) apparently occurs only in rather special
situations...
However, my problem was related to using SDMAC-04 with RAMSEY-04, which is an
incorrect combination. The SDMAC-04 thinks the RAMSEY can do non-longword
aligned DMA transfers (RAMSEY-07 can, and SDMAC-04 was designed for use with
that RAMSEY rev) and RAMSEY-04 then generates an incorrect address count for
such operations, resulting in data corruption.
Dave suggested that setting Mask=0x7ffffffc for the SCSI partitions might help
in trying to restrict SCSI DMA transfers to longword aligned buffers. However,
I never tried that, because I managed to go back to SDMAC-02 and RAMSEY-04 (a
correct combination, the configuration the machine was shipped with originally)
by experimenting a bit more with the jumper settings. Now everything seems to
work fine, and the wierd SCSI problems has disappeared.

Nope, I have a rev 11 Buster and it works great.

Well, maybe we are getting somewhere now - by (removed) do you mean
(open)? In which case, for J100, are you saying for a A3000T (normal030) you
would jumper pins 1-2 only, but for an A3000T (A3640) you would remove
the jumpers completely? So there would never be a case where pins 3-4
would be jumpered for an A3640?
So for an A3000T with the 74F08 installed, (column 3 above) I should
have
the following setup:
J100 1 2 3 4 (no jumper)
J102 1 2=3
J104 1 2 3 (no jumper)
J105 1=2 3 \
J106 1=2 3 --Do these three all control the 74F08 functions?
J107 1=2 3 /
^
|
= symbol represents jumper between pins....
Looks like J100 and J104 could be causing my problem, as I moved the
jumpers, and did not remove them completely - which works for Buster 07
but not for Buster 11 - would that make sense????
What about J103? - Mine currently is jumpered 1 2 3=4.
Thanks,
Bob

"J100 1-2 (closed)" means 1-2 must be closed...

Jumper 100, 102, 105, 106, 107 use one pin, that is not connected to anything.
There is no difference if it is closed at these positions or simply removed!

Fully correct! J105, 107 disable the normal 74F244 to use the 74F08...
J106 seems to be out or function if permanetly closed.
Don`t do so...it`s a shortcut at outputs for the "not deactivated"
74F244;-)
