No. The A3000's that your dealer currently has loads in the kickstart image from the hard drive and uses the MMU to map it at $F00000. >Do the CHIP and FAST ram areas use the same kind of ram? (and can you order >more than the default amount pre-installed.) Yes. The fast ram area accepts to types of chip pinouts. The usual DIPs and exotic ZIPs. They won't be so exotic in a few years. If you want to add more fast ram, the right thing to do is take the DIPs out of the fast ram DIP sockets and plug them into the chip ram DIP sockets. Then plug in ZIPs in the fast ram ZIP sockets. You may plug either 1 megabit or 4 megabit ZIPs in there. Valentin -- The Goddess of democracy?

What I am saying is can you simply move the shipped 1 Meg of fast ram over to the chip ram banks and have 2 Meg of Chip ram and 0 Meg fast Ram? Is there a hardware reason that you could not do this?

Using a genlock on the A3000 raises a question about the monitor. The A1950 looks great but can it be used with a genlock? I don't think it has any composite input like the A1084. One of the best Amiga features is having one monitor "do it all". I know it would be more expensive but is it possible to build a multisync with RGB and composite inputs?

Is there a hardware reason that you could >not do this? Dave? There's no hardware requirement for Fast RAM being there. I've run 3000s in the lab without it under 1.3 many times. As currently shipped, the magic EPROMs in the dealer 3000s count on that memory being there. I don't know what 2.0 plans once it's firmly in ROM. >Monty Saine -- 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

That's why I chose a Mitsubishi DiamondScan. I believe its list price is about the same as the 1950, but widely available for much less than 'suggested' retail. When I saw an A3000 with a 1950 monitor this past Saturday, I made it a point to see if the 1950 has a composite input. It doesn't. --Rich

(Don't race over to your dealer to try it out on his demo A3000 though :-)) But shipping it with 1 Meg in the fast ram slots gives you a better performance. Fast ram is not accessed by the custom chips, thus the CPU can hog it as much as it wants. Once you buy yourself a 3000, (you will, right?) try out benchmarks with only chip mem, and then try them out again from fast ram. You should see at least a 10% improvement, depending on the resolution your current screen is in. Valentin -- The Goddess of democracy?
