Must have Zorro cards or other hw?

[alexh]

Guys, if you want RTG graphics, you should want PCI or PCI-Express, NOT Zorro.

1) There is no PCI-Express solution for classic Amiga's? (cept I guess you could use a standard PCI->PCIe bridge)
2) All PCI bridgeboards for classic computers bridge to the Amiga via Zorro.
3) There are no / few software developers for classic AmigaOS these days. Any new hardware would require new drivers. Old hardware can use pre-existing drivers.

If you want Memory (ZorRAM), you want that via a more native addon, NOT Zorro.

ZorRAM you can buy new. Native accelerators you cannot?

If you want ethernet, is there not already a native addon planned that includes ethernet? But again, PCI/PCIe should be preferrable to Zorro.

See answer above.

Again for Deneb, is there not already USB port on a native FPGA Arcade addon? (I want to think it is on 68060 addon, along with ethernet) Why go Zorro compared to native or PCI?

Why have you pushed this thread to be about FPGA Arcade? Is this somehow linked to another thread? [Edit: Ah I've found it. Would have been nice if freqmax had mentioned this in his first post]

For the price of an "FPGA arcade + 060" you could probably buy one of each Zorro card ever made?

I always wondered if they could make a driver for the VGA and DVI USB adapters that are out.

Yes but it would almost certainly suck.

AFAIK these USB cards were designed

a) To have very fast CPU's behind them for software compression
b) To be able to use the full bandwidth of USB2.0 (20+Mbyte/sec)

Pretty sure that given a low power CPU and then capped at 4Mbyte/s they would suck big time.

As for PCI-Express, there's a handful of PCI32 adaptors, and then you can get this adapter supported with those:

I work for the company that designed the chip on that card. Doesn't work very well with newer gfx cards (at least on a PC) :-(

I was expecting it to be a PLX chip, I believe their adaptrs in the opposite direction used PLX.

Yup, probably the same chip used in both, the PEX8112. Works in both forward (PCI host -> PCIe card) and reverse (PCIe host -> PCI card). I play with them at home from time to time with classic systems.

To little bandwidth on the PCI side?

Possibly. I fear that for some reason the PCIe drivers for gfx cards are not 100% "transparent" as they should be. They don't seem to like being connected to the south bridge PCI. I assume that is because they are so used to being connected to a Northbridge (or CPU) PCIe and perhaps utilise speedups which don't work?? Who knows if this would be an issue for an Amiga.

Everyone I've tried worked. Look at the guide in Poseidon? (USB stack software)
