Hello!
Recently I've updated every chips inside my A3000.
Now I have also the Super Buster 11. I've noticed that, if I run the computer with a accelerator card (in my case a PowerChanger 040) everything works as it should but if I run the A3000 with its original CPU (68030/16), after setting all jumpers for this configuration, zorro cards are not recognized. It happens only with Super Buster 11. Using my old Super Buster 7 cards are 100% working.
Is it normal? Is Super Buster 11 compatible with the original A3000's 030/16? Otherwise, could my Super Buster 11 be defective or what could be the cause?
Thanks in advance!

This certainly is an unusual problem. Are you sure the jumpers are correct? As a 16mhz clock vs 25mhz clock would yield these type of problems.

you shoud try to run accelcard in async mode it its possible
i had similar problem with my g-force 040, and it needs one command before setpatch, iirc its "gvpcpuctrl async"
-
That is normal. The Buster r. 11 doesn't like being run at 16 MHz. In a 1997 usenet message, (http://groups.google.com/group/comp.sys.amiga.misc/msg/ffd0c1008492f67f?dmode=source&hl=en) Dave Haynie explained it this way:
There have been reports of trouble with Rev 11 Buster in 16MHz A3000s.
This was supposedly tested and approved by PA at Commodore. But by
then, we weren't making 16MHz systems anymore, so there wasn't much
testing or simulation done in Engineering, if any, for the later
Buster revision.
It works when your PowerChanger 040 is installed because the Buster is then getting its clock signal from the accelerator card. It probably supplies a 25 MHz signal.

I think it is the cause and that Super Buster 11 does not work properly with 16mhz. Newt week I'll get a Cyberstorm 060 and I'll test again with the new card and... I hope it will work ;-)

the MK2 works in INT CLOCK mode while the PowerChanger040 works in EXT CLOCK mode.
-
Accidenti, sei sicuro? Vale sia per la 16 che la 25 mhz?
Questo potrebbe comportare qualche problema... la persona che mi spedirà la Cyberstorm mi diceva che l'unica modifica da effettuare sui jumper è proprio il settaggio da INT a EXT.
Sorry guys... Italian is faster, after I'll translate to English, too ;)
-
si la MK2 va in INT Clock (mentre per esempio la MK3 e la PPC in EXT).
Non ho diretta esperienza sul 3000. Che quarzo hai sulla mobo?
Edit- dovrebbe essere questa la tua mobo
A3000 rev 6.1 (http://www.amiga-hardware.com/download_photos/a3000rev61mb_1_big.jpg)
con un quarzo da 32 Mhz. Giusto?
-
Dunque credi che il Super Buster 11 non andrà nemmeno con la Cyberstorm? A quel punto l'unica soluzione sarebbe cambiare la mobo? Certo che sarebbe assurdo.
Non ricordo da quanto è il quarzo, domani la devo aprire, controllo e ti faccio sapere...
-
il problema è che la MK2 prende il clock dal quarzo sulla mobo (che è un 32 Mhz).
"potrebbe" essere sufficiente sostituire il quarzo da 32 Mhz con uno da 50 Mhz ... ma è molto meglio che tu chieda a qualcuno che lo ha già fatto.
-
Se il quarzo fosse già quello da 50 basterebbe posizionare i vari jumpers sulla posizione 25mhz e potrebbe andare, giusto?
Appena possibile verifico il valore del quarzo!
-
si se fosse da 50 Mhz saresti a posto ma dubito visto che i 16Mhz della CPU sul tuo 3000, vegono ottenuti per divisione, dal quarzo da 32 Mhz.
Comunque meglio continuare in inglese altrimenti qui ci .... :-)

yes honey :-)

I hope so. That would make for 50 pizzas and we could all have some here at amiga.org :-)
-
absolutely! but not before my dayly lesson of mandolino!
-
Well, while I was eating my pizza and playing a mandolino... :lol: :lol: :lol: I have opened my A3000 to check the crystals:
- U111 = 28.37516 MHZ
- U104 = 32.000 MHZ
I'm so worried... :-o :-o :-o
I can't believe that Super Buster 11 will not work with the Cyberstorm 060 and my A3000 :-( :-( :-(
-
better to wait when you'll receive the CS.
I recall a friend with an A4000CR (without any 50 Mhz on the mobo at all) who lended in a not working Mk2.
Even better wait some answers from someone who already tryed a MK2 with a 16 Mhz A3000.
-
Yes, I'll do.
Meantime I hope to get some hints by A3000 030/16's owners :idea:
-
You could solder in a 25MHz 030 and just reset your jumpers to 25 MHz ;-)
I recall the MKII having a rather lot more jumpers involved than the MKIII, but maybe that was the MK1, which had all sorts of jumpers for the memory SIMM size etc. Probably to make up for various timing issues with the motherboards it could be plugged into.
As an aside, I'm trying to learn Italian from a set of CDs called 'Learn In Your Car' and I'm only on the second disc, telling time. So, trying to read all the Italian passages here is quite informative. Io non capisco so far ;-) But I'm working on it. Thanks for the Italian!

My mobo is different, it's a Rev 9/02 even if the CPU, the FPU and crystals are the same.

Super Buster rev 11 causes compatibility problems with a LOT of stuff in the A3000.
SB rev 11 was only originally installed in the A4000. The latest revision the A3000 got was rev 9.

According to Amiga 3000's owners experiences, SB11 should work well in 3000s.
However, I've just found a very interesting text written by Dave Haynie about Super Buster chip revisions (it is different than the one reported by amiga-hardware).
Here is a little part:
There are only three released Buster chips: Rev F & G, used in the A3000,
and Rev I, used in the A4000. The only functional difference between Revs
F and G are that F runs only at 25MHz, while G works at either 16MHz or
25MHz. F and G are what we called "Level I"; they support basic Zorro III
functionality, but don't support Quick Interrupts, Multiple Transfer
Cycles, or Zorro III bus masters. The part shipped with the A4000, Rev I,
is what we call a "Level II" part, which was designed to support the full
Zorro III specification. However, it has a problem with Zorro III DMA
which wasn't detected until after the A4000 shipped. So a replacement part
was built for use with the A4091 or other Zorro III bus masters.
Up to that moment (1993), the latest SB rev was 09 but the most interesting part is when he refers to rev "G" - such as Super Buster 07 - like the only Buster that can work both with 25mhz and 16mhz. Others work fine only on 25mhz machines.
Well... I hope that CV060 MkII will bypass all 16mhz limitations otherwise I will not allow to use the Cybervision 64 and that should be a shame :pissed: :pissed: :pissed:
