Differences in A3000 Motherboards

[VingtTrois]

I just got a hold of a couple of rev. 9 A3000 motherboards.  I already have a sweet system built with a rev. 7.3 and am wondering if it would be worth tearing down my whole system to upgrade the motherboard with the newer rev.

Any ideas?

Perhaps some new rev. of chipset: look Western digital SCSI and other chips.

Do you have the rev.7.3 A3000@16 ou 25Mhz ?
Nothing really new between 7.3 and last Motherboard otherwise ROM modifications.
