But by the time you get up to SIMMs/DIMMs it all has to go through the onboard memory controller, doesn't it? That's the reason I haven't put faster RAM in my 386, even though 12MHz RAM on a 40MHz system is an obvious bottleneck: the memory controller can't keep up with anything faster.

Really, that's the problem with the whole idea: there's a lot of hardware in the Amiga that's designed to be superceded by things like RTG, but not replaced with a functionally-equivalent enhancement. In order to replace all of it, you'd likely have to replace so much of the system board that it'd be easier just to build a full system replacement...

What about something like the Graffiti card??
I don't have one, so I don't know...

But could it, in theory (there's no WB driver?), run a faster higher color WB?

Or would you have to rewrite the AmigaOS (partially) to display chunky/Graffiti mode?

Any possibility of a Graffiti like RTG driver or ???

Again, no idea, just checking..

I do have a DCTV..  Someone could do that?  ;-)

(p.s.  I think Indivision MKII has a Graffiti mode, is this where the possible later faster mode would come from or ?)
Amiga 1200 w/ ACA1230/28 - 4G CF, MAS Player, ext floppy, and 1084S.
Amiga 500 w/ 2M CHIP and 8M FAST RAM, DCTV, AEHD floppy, and 1084S.
Amiga 1000 w/ 4M FAST RAM, DUAL CF hard drives, external floppy.

What's a Graffiti card? especially how does it work?

As for rewritting.. no source - dead end. And a lot of work.
The only realistic path is AROS.

I didn't mean that it could happen.  I just wondered if technically that's what it would require..
Also, Workbench replacements are possible, ala scalos?

The blitter should be significantly faster (unless they slow it down for compatibility) and would work with the faster gfx memory to give even a bigger speedup. The RTG chunky modes will reduce the amount of work needed also providing a speedup.

On the older Minimig 1.1 you can enable fast mode and it does indeed make ECS really fast and nice. Blitter speed is really substantially increased and you don't get slowdown running in overscan mode. I run my Workbench and Cygnus Editor in 728x283 in 16 colors which would probably kill a real ECS amiga.

I am totally convinced FPGArcade is the future because our hardware is aging and really is pretty maxed out as far as expansion capabilities.

There's an idea, except that I have the original Indivision AGA.  Actually I kind of like that I got that anyhow, since I have the VGA of it, the DVI of the Radeon and HDMI from my main PC all connected to my 24" LCD.    But if it's just a driver update, the question is will it work with the Indivision that I have?

I don't think the original Indivision will be able to do the Graffiti mode(sorry). From what I understand the original and MK2 are totally different hardware which probably why the firmware and utilities for the MK2 are taking such a long time.

I don't even think the trick of turning off video DMA is definite yet, but if it pans out I hope we see a lightning fast ShapeShifter driver that uses the combination of that and the Graffiti...

If there was a workbench driver like there is for the Indivision ECS that would be really cool.

That would indeed improve the shortcomings of AGA (DMA slowdowns and lack of chunky mode) and probably be the closest thing to "Super AGA" as an add-on you'll see...

There is P96 and CGFX. P96 is freely available so all that is needed is a P96 driver. That is the route the fpgaArcade is taking. It's much more flexible than the Graffiti.

Every ole who have 040 or better should installa and configure FBlit.
It makes big difference.

I believe I have FBlit installed.

Actually I have set up the ClassicWB for OS3.9 installed, and I think it comes with that.

It's still a huge difference between the AGA chipset and the Radeon card.

If only I could figure out what is causing the Radeon resolutions to lock up.
