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.

[starf81]

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!

Edit- dovrebbe essere questa la tua mobo

A3000 rev 6.1

con un quarzo da 32 Mhz. Giusto?

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:
