Different Buster Versions
« on: December 24, 2022, 12:37:04 PM »
Whats the difference between buster rev 06 and rev 07? My 3000T had 07 (now upgraded to 11) while my 3000D has 06? Any advantage / disadvantage of using the 07 part in my 3000D?

Hi Tumbleweed,

I did a bit of research and found this: http://www.wonkity.com/~wblock/a4000hard/defibust.html

"Next we consider the Buster chip. The Buster in the A3000, Rev 6 or Rev 7, is a well proven design. The difference between the two is only that there was a small bug in Rev 6 that caused it to fail at 16MHz, but it works fine at 25MHz. These are what we called Level I Busters; they don't support Zorro-3 DMA or Quick Interrupts, and they don't attempt to translate local bus burst cycles into Zorro-3 burst cycles."

Thanks Andy. I swapped the rev 6 part with the rev 7 but soon found myself getting checksum errors, read/writer errors on my SCSI2SD. The boot partition soon became non bootable. I then switched back to the Rev 6. Reinstalled OS3.2 and have had no issues since.
