PCI-X to x4 PCI Express Adapter Card

[ArmorAlley]

For example, https://www.startech.com/en-eu/card...73YXOlr4BUPGUkFmTZ1UxKQIjqfo_3Fbe71wJtW0CNx-C

I'm new to the G5 and PCI-X.
I suspect that these adapters are no really available and probably a healthy price when they occasionally appear on eBay.
Or are they actually available anywhere?

Does anyone have any practical experience with them?

I went looking for one on the off-chance that I could stick my Sonnet Tempo SSD into my G5 2.0GHz DP.
The problem with almost all PCIe cards is that of drivers not being compatible with 10.6b and below.
There may be some graphics cards that would work with it.

PCIe to PCI cards are available and these are easy to find on eBay, but I don't really see the point of them, unless you have the 1,6GHz G5.

The startech version is the only one I've seen (www.startech.com/en-us/cards-adapters/pcix1pex4), but I've never seen one for sale. This was the last place I tried: www.tamayatech.com/parts.php?g=PCIX1PEX4

Lack of demand I presume, silicon is still in production but is expensive (e.g. PI7C9X130DNDE, which can do both way).

I've connected PCIe Nvidia 7800GT Mac Edition from my Quad G5 in a B&W G3 using a StarTech PCI to PCIe adapter. There's some notes about that and PCI/PCI-X to PCIe bridges at:

A PCI-X to PCIe x4 adapter would maybe perform twice as fast in a 64-bit slot of the B&W G3. The G3 has a 32-bit slot that runs at 66 MHz but I don't recall if I tried that. The 32-bit slot would have a similar performance to the 64-bit 33 MHz slots if the 32-bit slot was able to do 66 MHz.
