why you say that the a500 is worse than the a600 ?

Well, since we were talking about video display, I was referring to the fact that the A500 (non-plus) is OCS and the A600 is ECS. Maybe the chip architecture meant some added difficulties with this sort of thing, I thought... Also, I was under the impression that the A600 is more efficient - energy-wise - than the A500 and thus an expansion board for the A600 would require less power than an expansion board would on the A500. Of course, when it comes to these technicalities, I'm virtually a layman, so nothing of what I say is to be taken for granted. I was just speculating, hence why I posed the question.

Implementing SAGA doesn't make much difference whether the architecture you are replacing is OCS, ECS or AGA. There may be a bit more house keeping to do for AGA or ECS but not much I think. I don't know if the A500 busses and CPU control signals draw more current than on the A600 but if they do then the power available to the A500 CPU socket and hence the Vampire is likely to be higher, also the 68000 CPU doesn't remain in situe like on the A600 so no power is wasted on a redundant CPU.

The Rev6 A500 is easily capable of being modded to 1mb chipmem, mabbe now is a good time to think of doing it

It will for sure.

A Full HD 16 bit frame is about 4MB so you wont get many frames per second from it with heavily animated images.

Even though Zorro II is limited regarding memory & bandwith, there have numerous graphic cards with 4MB that work admirably well on such systems. Just to name a few: CyberVision 64/3D, Picasso IV and Merlin.

The practical advantage of using Zorro II as a bus interface is that you can serve A2000, A3000 and A4000 users (plus its model variants) with a single design. You can even enable a Zorro III mode for enhanced bandwith on systems that have such capability, as it has been done before on numerous ocasions.

And who says you have to use ZORRO? Can't you just pop it in the 68000 slot just like the A600 one snaps onto the 68000?

With a 68000 cpu slot gfx card, you can only serve the A1000, A500 and A2000 plus its variants, but then you miss on the A3000 and A4000 and all its related variants. Furthermore there are plenty of easily available Zorro adapters/busboards for many non Zorro Amigas (for A1000, A500 and A1200 at least).

Anyway, I would gladly pay for a Zorro II gfx card with the current framebuffer design the Vampire has.

I think majsta planned to make gfx cards from the remaining cyclone II he got for the first revision of the vampire.

I love the A500 design but the PCMCIA slot in the A600 is really useful for networking / CF cards.

I'm interested in buying one for the A1000. I just hope that there'll be an expansion with USB and/or ethernet so I can easily get stuff to and from the machine.

some new updates on the horizon , Amiga flashing is now a reality and there are improvements in the core and a few new features, keep an eye here for the updates once pretesting is done.

quick addon... It takes 9 seconds to reflash the core on your amiga

i upgraded my core to 13x (92mhz),
adoom gives 20,5 fps with a screen of 640x480...

I'd like to add that this is the beta 64mb board, the release board will be faster

maybe, but i am satisfied of my little developer board !

Impressive, especially for such an early release. The core must be executing, roughly, close to 2 integer instructions per cycle. This is very good considering a "hard" CPU like the P1022 PPC in the Tabor is limited to 2 integer instructions per cycle.

More memory shouldn't make much difference in speed. Is the FPGA different on the release board?

[lantus360]

nice. updates are welcome

for anyone interested, i patched AmiDuke on Aminet to use 320x200 ECS 64 Color EHB mode so it can run on the Silver core. its completely unoptimized and still manages to run quite nicely heres a video

Core is constantly being tweaked, as such cgugls score came from an earlier core, the memory speeds and cache has been updated in the last few days so there should be an improvement in performance

Nice video lantus360.

The p96 should be available very soon so you'll be able to try Mac fusion and other apps/games

[lantus360]

nice! i will likely update some of my ports - Strife AGA, Rise of the Triad etc to support

Impressive vampire results. Not impressive cyberstorm results. Were the caches off, like before running setpatch so 68060.library etc hasn't loaded and turned on the caches?
