AC 450 board
Does anyone knows if it is possible to use the communication board (that from pc) to AC450 with any kind of usb converter?
I've find a isa/usb converter but not the pci/usb.
The only good host for a PU515(A) RTA PCI card is a proper computer.
PU515 require 5V PCI bus. PU515A runs on both 3.3V and 5V. The PU515 PCI connector is keyed to prevent putting it into a 3.3V slot. The PU515A have two "cuts" and will fit in both a 3.3V and a 5V socket.
Try finding a certified used computer on eBay, eg a HP DL 380 G5 or G6 with the PCI-X riser cage that can fit an RTA (the default riser cage only handle the newer PCIe bus type)
I believe the G6 requires the larger 1200W power supply option. For some reason the G6 supplies less PCI power than the G5 did and the RTA draws *FULL* PCI spec power at boot. The G6 default power supply (900W?) may not permit a successful RTA boot.
