I have two questions concerning the A3000 that I would like to know the answer to. First, is the oscillator for the '882 and '030 on the motherboard socketed? If so, can it be replaced with, say, a 60 MHZ oscillator to get a 30 MHZ '882 and '030? Second, what kind of real world speed increase is realized using SCRAMS on the 3000 instead of PAGE MODE DRAMS?? Thanks for your time.

No. Neither are the 68030 or 68882. >If so, can it be replaced with, say, a 60 MHZ oscillator to get a 30 MHZ >'882 and '030? Since the rest of the chips in the system aren't likely to run at 30MHz any more than the 25MHz 68030 or 68882, this is Not A Problem. There are no quick and dirty enhancements; if you want a faster system, you'll have to wait until a real, correctly design Coprocessor slot card is available. >Second, what kind of real world speed increase is realized using SCRAMS on >the 3000 instead of PAGE MODE DRAMS?? We estimate about 20% speedup, though of course the increase is software dependent. > Chris -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "I have been given the freedom to do as I see fit" -REM
